Best BIOS ROM for Sapphire Nitro+ RX 580 8GB OC Hynix Memory 30+ Mh/s

Ledger Wallet protects your bitcoins

I had the chance to make a quick mining hashrate test on Sapphire Nitro+ Rx 580 8GB GPU (thanks to Novan), after few tries and a bit of research i have found the best timings for this card, at least for now.

I know a lot of you guys were waiting for this post but i was really busy testing other cards from 500 series and also building frames for rigs.

The max hashrate i could get is 30.2 Mh/s on Ethereum and on dual 30 Mh/s Ethereum, 870 Mh/s for Decred and 300 Mh/s on Pascalcoin, with 130w – 150w power consumption.

So like i said, those are some quick/fast tests via teamviewer, didn’t had the chance to play more with the settings or bios for too long, but we god some good results, i am pretty happy with. For sure there is still room for improvements (if not hashrate then maybe power consumption) but at least this is a good start.

Sapphire Nitro+ RX 580 8GB Mining Performance Review

Like always, to not make any confusion on card, here is the exact model for this tutorial

1 Tools and Software needed

NOTE: I already did a similar tutorial for a RX 470 4GB and i will link some points there to avoid writing the same thing over and over again!

IMPORTANT: Before starting to make any bios modification, install and combine AMD Drivers and do not restart, start atikmdag-patcher.exe and apply the patch (if needed), after this you can restart the pc. If you don’t this the GPUs wont work with the new modded bios flashed.

2 Backup OC BIOS

3 Switch BIOS

4 Backup “Silent” BIOS

Before to continue further, please share this 🙂 thanks!

5 Download BIOS

Important, this BIOS is for Hynix memory only! Check your memory with GPUz software

You can test both versions, basically the V1 should use less power than V2, but you can test both with same settings and compare the results. No undervolt was applied in bios, you must do it from trixx, msi afterburner or claymore miner.

6 Flash BIOS with ATiflash

VERY IMPORTANT: Always extract ATIflash to C:/atiflash folder and place the ROM file that needs to be flashed in the same directory
6 Claymore 9.3 + underclock + undervolt

  • Download and extract Claymore miner
  • Right click on start.bat fileand click “Edit
  • Paste the following code: “EthDcrMiner64.exe -epool eu1.ethermine.org:4444 -ewal ETH_WALLET.WORKER_NAME -epsw x -dpool dcr.suprnova.cc:3252 -dwal SUPRNOVA_USERNAME.WORKER_NAME -dpsw WORKER_PASS -tstop 85 -tt 65 -fanmin 60 -fanmax 100 -cclock 1130 -mclock 2150 -cvddc 850 -mvddc 850” (replace details with yours)
  • save,close and run start.bat

If you are going to use my claymore miner code then there is not need to start Sapphire Trixx or MSI Afterburner to make changes on clocks or undervolt. With this settings added, claymore miner can give same or even better results than Trixx or MSI.

However if you are going to use Trixx or MSI Afterburner set the following vales

  • GPU Clock: 1150 or 1130
  • Memory Clock: 2150
  • -mV: 100 or 150 (for msi -100 is max)

Power draw (dual mining only)

  • GPUz: 90w – 95w
  • From wall: 130w – 150w

Hashrate

  • Ethereum: 30.14 Mh/s
  • Ethereum + Decred: 30 Mh/s and 870 Mh/s
  • Ethereum + Pascalcoin: 30 Mh/s and 300 Mh/s

Full 6x GPUs rig should draw around 1100w with this settings!

That’s it guys for the first 500s GPU tested by me, I hope this will be helful for many of you.

Also let me know what are your results for hashrate and power draw for a full rig, very important if possible to attach screenshots.

Thank you for reading. As always, your comments, suggestions and questions are welcome.

    Maybe this was answered already but why Claymore 9.3 and not 9.4?

    • The test was done few days a go, 9.4 was released today.

          hi i have same card like you what strap did you change please? 1:… or 2:…. and from where to where did you copied please?
          this is my configuration
          i copied from 2:1750 to 2:2000 and 2:2250 overclock 1150 memory clock 2080 i get 26,3 mh, if i set more than 2080 on memory clock pc crash.

    Please help me, make a tutorial of this for the same nitro + 8g card but with samsung memory.

  • Fábio Soares

    What should I do for the one who has samsung memory?

    Hello Ciprian!
    How to convert “-cvddc” and “-mvddc” value from Trixx to EthDcrMiner64?
    For example with the RX470 8GB i’m using -96mV…. Is the right value: stdby value – 0.096?
    Thanks!

    • Kürşat Konak

      No. They are only OFFSETS, check from GPU-Z to learn your real /mcvddc. For example Trixx says its -150Mv, but in fact it is 850 (1000 – 150), then put 850 as a parameter to miner.

    • Hi, -cvddc 904 and -mvddc 904

  • Fo

    When building a 6 GPU rig with these, how do you overcome of the 8+6 pin power connector issues? I don’t think even a 1500W Corsair PSU has that many connectors/cables.

    • AleraKira

      My RX580 Sapphire Nitro+ runs exactly the same as my RX480 Sapphire Nitro+ both using only an 8 pin. This seems to be correct as with a wattage of 100W, the card is pulling 150W from the 8 pin and 75W from the PCI-E 3.0 slot which is enough to power it even when overclocked due to the BIOS changes.

      Hope that helps and maybe Ciprian or someone can add onto or correct me!

      • Fo

        Thank you for your response! So is the 6 pin connector solely there to 1) provide some extra support for the motherboard 2) extreme overclocking? I know it is not designed that way by AMD. Even the sapphire site says it’s optional (found it just now) so I wonder what they were thinking.

        • AleraKira

          Yeah it seems that way, when a GPU is running normally with clocks up to 1411 or higher, the extra power is needed to keep things stable otherwise you can get BSODs and shutdowns.

          Interesting that it says it’s optional though!

      • kkourmousis

        I having 1 single GPU and I was wondering if there is any point on disconnecting the 6pin. Will it save me any power?

        • AleraKira

          It doesn’t look like it saves any power at all, probably just helps to stabilise the loads across several lines.

    Hi,

    I have sapphire rx580 4gb oc with hynix. Can i use this guide to bois mod or there are different setings for 8gb and 4gb edition. I know that different settings aplly for samsung or hynix memory.

    • Hi, it wont work with 4gb version, send me your rom and i will modify yours.

        hi, I downloaded couple of ROMs and I really messed up (I have sapphire nitro+ rx580 4GB hynix mem) amnd Hashrate fell down from 24 to 12 after using file for 8gb uploaded by Jaro two days ago in the comments. Then I created my own rom by copying 1:650 to 1750 and 2000. now it is back to 24. What would be the best thing to do?

        my original rom:
        https://we.tl/k1lYP4CLHi

        also, i tried another one of my identical cards after the 12MH flop and it was 12MH too.

        • drx3brun

          Which editor did you use to modify this images? Thanks.

          • Filip Grzejszczyk

            used atiflash

          • drx3brun

            Thats for flashing. To edit the image you need Polaris Bios Editor. Problem is there is plethora of versions/forks of the original one and I am getting on which one exactly people are using to edit images for RX580’s.

      • Cougar

        well, did you do it? i need this too. thanks.

        • Damac

          Hi,

          I got working rom for Sapphire RX580 Nitro + 4GB Hynix on another site. For now Im testing it few days and its working OK. Test results with Claymore dual miner are around 28MH/z at 70W use (cpu-z), GPU temparature from 49-52 degres and 17% fan speed.

          I didnt do all the steps that are mentioned here to apply new rom. I only enabled silent bios, and create backup of original rom with AtiFlash and then apply this new rom. Reebot computer and thst it.

          I added in batch file for Claymore to use a bit higer memory and cpu:
          -cclock 1100 -mclock 1950

          Link to this new rom:

            is this hynix ram?. can you adress the site too? thank you.

          • Damac

            yes its hynix. here you go: https://anorak.tech/c/downloads

            there are roms for almost all GPU-s for mining

          • Cougar

            well poorly efected and resets itself. mh now 26 mhs

  • ridwan

    Help me sir, I have powercolor rx570 4gb with hynix vram.. but i can only reach 21 mh/s with modded bios and overclocking, I use timming 2:1500 copy to upper then I use 2:1625 copy to upper, but no effect, It seems my vram type is hyinx and elpida (EDW4032BAB and H5GC4H24AJ).. Can you give me the solution please!

  • Bart

    Hi Ciprian,

    I have new rig with 6 x SAPPHIRE NITRO+ RX 580 8GB (luckily all with Hynix mem),
    after this guide on dual mining i get constant 178MH/s reported and 170-220MH/s effective Hashrate. All cards running 60-65C with ~80% fan. Thanks alot for this guide

    • awesome 🙂 have fun !

    • Pingi Pongi

      Hi Bart,
      i have question about settings for sapphire rx580 nitro+ 8gb/4gb Hynix…
      I have above 4gb and 8gb card, and i have flashed 8gb with Jaro’s rom and Anorak rom. Now after my Trixx modification -> on 4gb i have set cclock 1100 and mclock 1950 and on 8gb – cclock 1130, mclock 2150 -> in claymore 8gb has 29.998MHs and my 4gb has 27.966Mhs, but…..8GB has 138W and 75°temp, 4Gb has 111W and 73°temp. Do you have any settings for Trixx, so i can lower power consumption and temperature?
      Thank you!

      • Bart

        Hi Man,

        I’m not really sure as I didnt use trixx for any modifications. I’ve just applied V1 bios from this article, and then recomended settings in claymore (-cclock 1130 -mclock 2150 -cvddc 850 -mvddc 850). I had my cards go up to 75C but it was really hot day outside, and ambient temp was really high.

  • kkourmousis

    –I just read your article and I am tempted to try your BIOS files. I have 1 RX 580 8GB Nitro+ and I am currently @31.8MH/s solo mining, drawing 145w from the wall. I am using Claymore v9.3 to mine and I am at 0.9V, 1150 on the core and 2250 on the memory clocks. I may give it a try with your 2 BIOS files in order to see if I can go even further :p

    1 question though, I did not backup my “Fast BIOS” because the switch is inaccessible inside my rig. Since I am not going to switch to “Fast BIOS”, nor I am going to flash it, do I have any risk of “losing” the “Fast BIOS” if anything goes wrong with my “Quiet BIOS” Flashing?–

    • Let me know the results! thanks!

      • kkourmousis

        I had written the results but I am new in Disqus and I didn’t know that editing my post would make it be detected as spam…

        So here I go again :p

        For starters, Both of the BIOS files, as well with the one I was already using, all have the same memory straps. V1 indeed appears to have some power modifications which should end to a bit lower consumption.
        So far I have the same (maybe a couple of watts lower). I think I noticed a couple of “spikes” in the power consumption, but I will have to leave it running for a lot more than 5 mins to have a safe consumption.
        It appears that V1 is not worse than V2, but I will keep testing it to see if it is any better.

        As for my early results:

        The only thing is that I seem to have some trouble stabilizing the Dual mining ETH hashrate. 80-90% of the time is 31.75 but I have seen it drop to 31.1 or even lower for 1-2 print outs. That and the +30w on dual, will keep me sceptical the next few days

        • Hi, well done:) butnyiu should lower to 1130/2150 , the power draw is a bit high I guess.. have you tried already ?

  • Pacman

    Do we need to mod the bios? Or is it possible to just underclock and undervoltage via Claymore?

    I guess we do due to timing?

    • You will have to flash this bios to have that results.

      • drx3brun

        Is it enough to just edit the images with Polaris Bios Editor in order to force the undervolting? Sorry for asking trivial question, but i do not have any Windows machine available to test this out atm.

  • Grant Southey

    Hi – went through everything and so far so good – but the trixx doesn’t report the gpu clocks/thermals etc. – gpu-z neither. only hwinfo shows it.. plugged into main 16x and second card in next 16x (xfire disabled) – tried afterburner to see as well..nothing. any idea on how to get secondary gpu(s) to report/listen to trixx?

    Got the GPUs finally reporting and sitting at 28.8mh/s (each) bios V1 (something with setting the mobo to igfx and plugged dvi into main 16x pci gfx slot) – 124w power though 🙁

    I can see and set fans etc. Finally. I tried the settings (claymore as in article) – machine tanked, had to pull out power and turn of psu for a few minutes. Luckily it returned to normal.

    Any idea on how to make the gpus purely secondary and see/set set the clock speeds and voltage etc. I don’t have space to use the other pci card ( or to swap to risers )

      I just found the solution, the 534k is not good for us we need to use the same but with 256k I tried to copy the first time but not successful, I just found out that it was because of the version I downloaded of Polaris Bios Editor, I’m about to upload the 256k modified bios v2 here for everyone, wait for it.

    Hi Ciprian,

    I am only a few weeks into mining and thoroughly enjoying it. Your site is tops, well done.

    I have tried v1 of your bios and I am getting 30.1 Mh/s (not dual mining)

    GPU-Z
    Gpu: 1130
    Mem: 2150
    Gpu Temp: 53
    Fan: 49%
    Power Draw: 78W
    VDDC: 0.8375

    The clocking and under volting are done via Claymore’s config and this is running on windows 10.

    Could this be done in Ethos ? I know that you cannot undervolt in Linux, however if you are using Claymore in Ethos and apply the command lines options ” -cclock 1130 -mclock 2150 -cvddc 850 -mvddc 850 ” would this work ?

    Alternatively, would it be wise to modify the bios further to achieve the same results ?

    Thank you.

    • Hey Nei, i did not tested in but it should work yeah..

      • drx3brun

        Unfortunately underlocking with Claymore doesn’t work with Linux, the options cvddc/mvddc have no effect (as stated in the docs). The only resonable way is to hardcode the values in the Bios. I am currently looking into this, and will probably try to modify the bios on next weekend.

        • Bossman

          Well i would want to know how to do it, otherwise ethOS is useless.

    Hi
    I just ordered 6 RX 580 Sapphire nitro+ and i noticed that pcie power port is 8+6 pin, do you have any idea what power supply should i use so that i can power up these cards.

    Does this PSU work?

  • Ivanov

    I just have one question. What are the bios settings for rx570 strix 4GB?Or if you have rom file for this card it will be great.

    Thanks!!!

  • kkourmousis

    Do I have the option of setting GPU Clock, Memory Clock and voltages directly into the BIOS so I will not have to use TRIXX, Afterburner or the Claymore settings?

    I am asking because I would like to keep my gpu without a monitor on it but I can’t OC my card without an active screen.

    I have a dummy plug on my hands too (which I made :p), I haven’t tried it on my mining PC yet ( I don’t know if there is any risk)

    • Grant Southey

      I think I have a similar issue in that if I don’t have the mining gpu active to screen I don’t see or am able to control fans. If I set OC, it bombs the machine..

      • kkourmousis

        Yeah exactly the same with me. + i claymore clock adjustments have no effect

        • Grant Southey

          What I want to know is how your memory clocks are at 2250 and 1200 core? This default? Or how did you change them?

          • kkourmousis

            Just in case you are actually asking how to change the clocks:

            To change them you must use overclocking software like MSI Afterburner or Sapphire Trixx OR you can tell your miner to do it, if you use claymore. Claymore Dual miner accepts parameters that can alter your gpu’s clocks and voltages, just like those OC softwares would do.

            Now that we got that out of the way, I am guessing your question is “how did I changed them without an active screen”. The answer is I didn’t :p I have a screen plugged in. Without a screen Catalyst drivers don’t let you OC.

            That’s why I am asking @ciprianpt:disqus if such thing can me done directly into BIOS, so I won’t care if Catalyst don’t let me OC the card.

          • Grant Southey

            I did that. Machine bombed. Had to unplug everything before it would restart.. 🙁 your gpu plugged into main 16x slot?

          • kkourmousis

            yes it is on the main pcie

            you did what? modded and flashed a BIOS with OC clocks and undervoltages? well I guess that answers my question :p

          • Grant Southey

            I modded the bios ( went from 22 to 28.8 – thanks @Ciprian) but the last steps of setting the clocks and voltage doesn’t work – machine stalls with white screen or won’t boot until
            I unplug everything..

          • Grant Southey

            Seems the -asm param and not running trixx same time sorted it. Whoot! Power is down from 125/140 to 75/75 (2 gpus)

            Next issue is that one gpu runs at 31.8 and the other at 28.8 still – clocks etc all the same for both cards. I wonder if the difference in ASIC Is the cause.. 4% diff

          • Sam

            How can you get this done? After modding my sapphire rx580 8gb bios with copying 2:1750 to 2000, 2250, and adding claymore parameter “-asm 1 -tstop 85 -tt 65 -fanmin 60 -fanmax 100 -cclock 1130 -mclock 2150 -cvddc 850 -mvddc 850”, i can only get 27MH.

            can you state which bios you use and what parameter you use?

            Thanks a lot.

          • Grant Southey

            I used the bios from this post, and 2250 mclock, cclock 1200

  • Dendy Oktavian

    Do I have to save every GPU’s default bios?

      Got same problem on 5 cards and 1 card is ok. 5 cards with 256 kb bios and if I trying to flash bios on them I got Cannot erase ROM from ATI Flash.

      • Jaro

        Hi Andrey I just found the solution, the 534k is not good for us we need to use the same but with 256k I tried to copy the first time but not successful, I just found out that it was because of the version I downloaded of Polaris Bios Editor, I’m about to upload the 256k modified bios v2 here for everyone, wait for it.

        EDIT: here it is, this worked for me getting 30mhs now (spent all the day to do it): http://www.mediafire.com/file/wf4exl9xgtc83uy/moddedv2.rom

        • Pingi Pongi

          Hi Jaro,
          i have question about settings for sapphire rx580 nitro+ 8gb/4gb…
          I have above 4gb and 8gb card, and i have flashed 8gb with your romv2. Now after my Trixx modification -> on 4gb i have set cclock 1100 and mclock 1950 and on 8gb – cclock 1130, mclock 2150 -> in claymore 8gb has 29.998MHs and my 4gb has 27.966Mhs, but…..8GB has 138W and 75°temp, 4Gb has 111W and 73°temp. Do you have any settings for Trixx, so i can lower power consumption and temperature?
          Thank you!

          • Jaro

            Yeah this happens because my romv2 uses the rom V2 of Ciprian V. (he states that the v2 will use more energy) I was hoping that using this I would get over 30mhs as I’m using more power, but after trying to create a romv1 I noticed there is no difference, I still reach 30mhs and I use 130w while with the v2 I used 180w, so I reflashed all the cards to the V1, you can try to download the one of Ashley Forrest, maybe that’s the V1 I’m talking about, if you need I will try to upload my v1 later. Good luck

        • Glen Pittock

          Hi @disqus_4TFQEeciJi:disqus!

          Thanks for uploading your ROM. This is the only ROM I could manage to install on my 11265-01-20G 20GSapphire Nitro + RX580 8GB Hynix without ATI Flash crashing or saying ‘Cannot erase ROM’

          But it the cards only output 27MH/s maximum on Genoil or Simple Mining Claymore.

          Do you have any idea what could be causing this or suggestions to get around it?

          I’m happy to make an ETH donation to anyone that can get my cards ticking at 30MH/s

          Thanks in advance!

        • Chris Smith

          Thanks for the upload I have been looking for days to up my rate on my sapphire nitro+ 8g special edition. I tried manually adjusting timings but for whatever reason this does better with current dag difficutly I am upto 28.5 mhs vs the stock 22 mhs. Thank you for the huge help.

      • Ashley Forrest
        • Ti

          Hi, Ashley! I got 6 Sapphire NITRO+ RX 580 8gb (Hynix) on my rig. So I flashed all cards with settings from your rom. I’m using ethminer-0.9.41-genoil-1.1.9. And now I got unstable Mh/s (like 30+30+15+15+30+15). Watch on screenshot, Afterburner settings also there.

          Miner settings:

          setx GPU_FORCE_64BIT_PTR 0
          setx GPU_MAX_HEAP_SIZE 100
          setx GPU_USE_SYNC_OBJECTS 1
          setx GPU_MAX_ALLOC_PERCENT 100
          setx GPU_SINGLE_ALLOC_PERCENT 100

          ethminer -G -t 6 -F http://eth1.nanopool.org:8888/0xfabb0459cd4651365f8b87cbfe3567a8edf75b9e/NITRO+/neega@mail.ru –farm-recheck 200 –cl-local-work 256 –cl-global-work 24576

          Any ideas what I’m doing wrong?

          • Ashley Forrest

            Hey, have you set your paging file to at least 16GB? If you have try using the claymore miner. 🙂

          • Ti

            Pagefile = 22 Gb.
            Claymore miner (in eth-only mode) now shows stable hashrate on each GPU; total hashrate =178 Mh/s.
            Solved!)

          • Ashley Forrest
          • Ti

            Well here’s what I did:

            1. Flashed vBIOS on all cards with factory ROM from here:

            https://www.techpowerup.com/vgabios/?manufacturer=Sapphire&model=RX+580

            I used one with 1450 MHz core clock instead of other one with 1411MHz.

            2. Then I started experimenting with
            memory straps:
            – Flashed 2:200, 2:2250 timings with strap from 2:1750 timing (Hynix memory) didn’t raised hash-rate at all;
            – Flashed 2:1750, 2:2000, 2:2250 timings with strap from 1:1750 timing (Samsung memory) raised hash-rate a bit (27-28 Mh/s).

            3. Finally I flashed 2:1750, 2:2000, 2:2250 timings with this strap:

            777000000000000022AA1C00B56A6D46C0551017BE8E060C006AE6000C081420EA8900AB030000001B162C31C0313F17

            (It’s from Caprian V’s ROM and it’s ONLY FOR HYNIX MEMORY. I didn’t find out from what videocard this timing is… If someone knows, please, share)

            ONLY SPECIFIED TIMINGS HAVE BEED MODIFIED. I DIDN’T MODIFY ANY OTHER PARAMETERS IN VBIOS.

            4. Then I used MSI Afterburner…
            After hours of tuning and monitoring I’ve found settings that gives stable 30 Mh/s rate on each card in ETH-only mining mode (total rate = 180 Mh/s) with 100-110W consumption and no any errors. Here they are:

            core clock = 1180 MHz
            mem clock = 2150 MHz
            core voltage = -66

            That’s it. I’ll be glad to hear your advises.

            P.S.
            From very first day one of my cards is showing strange core voltage and temperature values (in all apps):
            ~0.8V instead of 1+V, and ~42t instead of 50+t.
            But hash-rate on this card is fine. Any ideas?

          • Arnie Hill

            I love you dude. This totally worked. Getting 29.8

          • Ti

            Ok, guys. I continued my research in search of a best bios parameters. So here’s the REALY BEST ONE (Caprian V., sorry dude…) vbios rom I made myself for Sapphire NITRO+ RX 580 8Gb Hynix memory.

            256Kb version:

            https://mega.nz/#!96A1zS5B!l_XGEIQl6kaxaFWI99sMHIeRquI6pqpsvEQv_N490Dc

            512Kb version:

            https://mega.nz/#!RqxiRLhb!3l4PnBWeFgpoiCCQyxF5JxcQ6hbsmNmfIqvtYO4UTug

            Some details about that ROM:

            1. I took factory bios as a basis.

            2. Modified 2:1750, 2:2000, 2:2250 timings. Used this timing:

            777000000000000022AA1C00B56A6D46C0551017BE8E060C006AE6000C081420EA8900AB030000001B162C31C0313F17

            (By the way, this one is from Sapphire NITRO+ RX 480 4Gb Hynix memory)

            3. Modified GPU and MEMORY sections as shown on screenshots:

            https://uploads.disquscdn.com/images/5cd7096b270d357d87ef0243eb632f8c3877304e84c119622618ac882f39a458.png https://uploads.disquscdn.com/images/d8816ed269b259c72422c870e7e50ff17affdffc4583f8a720ac6f920bd3ad36.png

            4. Finaly, in MSI Afterburner set:

            core clock = 1150

            mem clock = 2150

            That’s it!

            I tested this in ETH-only mode using Claymore’s miner v9.5. Here’s my config.txt:

            https://mega.nz/#!k3JHiAzJ!lhgsIbH5mBDcZvUQcuCSOr2VZcKl88aQXs6e_OMPTNY

            Next, some statistics.

            You can see everything on screenshots:

          • Hey @disqus_8LuuwzNkwH:disqus, looks good 🙂 but what is the power consumption of your settings and why is this better? 😀

          • Ti

            Hey.
            From wall: 120-125W

          • trainmission

            @disqus_8LuuwzNkwH:disqus Now i try this bios , its only update bios ? thanks for sharing !

          • wizkid

            With your settings it is 155 only GPU Power, so the wall is even higher.

          • Ti

            100% you made mistake somewhere…

          • wizkid

            @Ti I used your mod directly, and copied your config as well. It won’t go below 137 now.

            See the screenshot below:

            https://uploads.disquscdn.com/images/e574468fd43ad290e317ee65aa862a812e814882be2ea9618dcbf53ffd647e9f.jpg

          • Ti

            You’re using dual mode, although I said that I used eth-only mode for testing.

          • wizkid

            @Ti Yes I know but even in solo mode it goes down only to like 108W. Any suggestions?

          • Ti

            Man, 120-125 from wall – is a fine result.

          • wizkid

            These are not numbers from wall. I get 135-140 on GPU so likely much higher on wall.

          • Ti

            You said that you get about 108W on gpu in eth-only mode. So from wall it’s about 120-125W.
            Soooo…?

          • Brock Huffaker

            This is awesome! Thank you so much! I was able to get out of the 21Mh/s zone with this. I do have one question that maybe you or someone else might (hopefully) be able to assist. I updated both my RX580 8GB Hynix cards once by one and got them hashing at 30Mh/s. But then when I plug them both in one hashes at 30 and the other at around 4. Using the Asus Prime Z270-P and have changed everything to Gen2 and enabled 4G decoding. Any thoughts?

          • Ti

            Try Gen1

          • Brock Huffaker

            Thank you! That seem to have done the trick. Now to hook up the other 6 :). BTW is it normal for temp, clock, voltage readings to be blank if you boot with your monitor using onboard graphics? I run Claymore and do not get any temp or fan updates and the fans seem to not even be pushing.

          • Brock Huffaker

            I spoke too soon :(. This thing is super unstable. Rebooting and crashing. This is crazy. It works just fine with one card. I’m hoping to get an 8GPU rig up and running. I’m failing so far :/

          • Nicolas

            I think that the problem is in windows, beacuse your bios isn´t signed. Or maybe Memory virtual at 16GB fixed the error. Or other problem, if is possible somebody over that.

        • Tonny Ma

          this is by far the best bios i’ve come across. @ash@disqus_DjrSVzMOWI:disqus do you have any other bios for any other cards? thank you so much!

          • Ashley Forrest

            No worries mate, this isn’t mine though, all I did was copy the one from the tutorial into a 265kb bios 🙂 no I don’t have any others, I have no idea what I’m doing!

        • Glen Pittock

          Hey @disqus_DjrSVzMOWI:disqus,

          Thanks for your upload! I gave it a shot but my computer freezes when I click ‘Program’.

          Any idea what this could mean?

          Currently the best I can get is 27MH/s with @disqus_4TFQEeciJi:disqus’s ROM, which he gets 30?

          Thank you for any feedback!

          • Ashley Forrest

            Hiya, it will freeze for everyone, just be patient and give it 5mins 🙂

    • Ashley Forrest

      I did exactly the same but it worked. here’s my 256kb rom:

          You’re welcome 🙂 yeah I spent like 6 hours trying to get it to work?

      • Tim Tharratt

        Thanks Ashley, this is working well. I’m new to all this, prior to the BIOS and these updates the GPU Fans where always on. I didn’t pay enough attention before, but I guess everything is running cooler with these settings?

        • Ashley Forrest

          No worries mate, so am I aha! Yeah the gpu’s will run cooler because they are running at lower core clock speeds and are being undervolted. The credit goes to the guy who wrote this tutorial though, I have no idea what I’m doing when it come to changing the bios memory straps!

      • Sam

        Thanks Ashley. It is the best bios I use for my card. What did you modify to the bios? Rather than change 1750 to 2000 and 2200, what else did you do to make power consumption lower? I can only get 27MH if I do it myself

        • Ashley Forrest

          You have to run the code he gives in the tutorial when you run claymore. Don’t bother with afterburner.

        • Ashley Forrest

          He did’t change any settings other than the memory straps in the bios 🙂

      • yong

        hi Ashley, i have download modify the bios with your file, but i only manage to get 28mhs, how to get 30mhs?

        • Sixsevenzero

            How many cards in your rig? 6? I can’t get 6 more than 2175 mclock

          • Sixsevenzero

            I run 6 cards on the rig. But only one of them is Nitro+ 8GB runs perfect at2250 even.

            hi, i cant go for 29.5-30mhs
            what else setting you have done?

          • Sixsevenzero

            Were you able to get my BIOS to flash? Only settings are important are the core clock and memory , other settings are for lowering power

  • Codrat

    I have a Gigabyte AORUS RX580 with Hynix memory. The default ROM doesn’t have 2 series of straps. In Polaris, only 0: appear.
    Link to it:
    http://www.mediafire.com/file/lmey4f7qo25qsuw/hynix_default.rom

    How should I proceed in modding this? I tried copying the 0:1500 line to 0:1625, 0:1750 and 0:2000 but the GPU crashed upon running the miner.

    Thanks!

    • Codrat

      I copied the straps from 1750 over 2000 and 2200. I managed to get it stable at 26.5 ETH, 480 SIA. 1100 gpu, 2150 mem, 975mV, dcri 18. Anything above that leads to crashes. Disappointing compared to the same GPU and Samsung memory, but better than stock values.

  • Ashley Forrest

    Great tutorial thanks for this. FOR ANYONE THAT ‘CANNOT ERASE THEIR ROM’: If, like me, the bios rom wouldn’t flash or would only flash some cards, here’s what to do:

    1) Download polaris bios editor (This version will read the memory correctly)https://github.com/jaschaknack/PolarisBiosEditor/tree/110aa3a5a0aeafe16bb0a96b53583e7e8e77999b

    2) extract polaris bios editor anywhere.

    2) Open the rom that wouldn’t flash from polaris bios editor

    3) Also open the rom you backed up on polaris bios editor.

    4) Copy all the values in the rom that wouldn’t flash into your backed up one. (ie 1:2250, 1:500, 1:1750, 2:2200 etc.)

    5) save the bios as a new name, not to overwrite your backed up bios

    6) Flash with the bios you just made from your backup bios.

    – the reason this works as the one on this page is 512kb but the one you have just made is likely 256kb.

    Hope I helped.

    • Ashley Forrest

      Note – only do this if you have an rx580 nitro+ with hynix memory and the bios provided still won’t flash.

  • Grant Southey

    Random question – would GPU ASIC quality affect mh/s? Both are clocked the same but on has 2mh/s less. Only difference I see in HWINFO is a 71% vs 67% ASIC.. identical cards.. should be the same?

    • Yeah, the asic quality does the difference.. supporting better overclocking and undervolting..

      • Maguary

        Better ASIC = better undervolt? Or the opposite?

        • yeah.. better asic.. better performance..

  • Pavel

    Hi, I copied v1 bios to my rx580 nitro+ 8g and it gave me 30.02mh, thank you a lot! My rest of GPU is sapphire rx580 nitro+ 4g (elpida). I modded BIOS (just copy 1:1500 to 1:1750, 1:2000 and Trixx 1360@1050, -100mV, 1750@1920) that gave me around 28,5mh. Do you have any idea how to change it? One of my GPU sapphire rx580 nitro+ 4gb has +29mh. Is any chance to avoid trixx on startup and keep all settings because I need to change every time manualy voltage?

    • Grant Southey

      Its not ‘keeping’, but you can Use the start.bat for claymore to pass the cclock mclock params etc. Remove trixx windows startup setting – you can even set per gpu 🙂 good luck

      • Pavel

        Thx Grant! Can you show me example how should be look this file? I tried to add this options to .bat, but not working. How to set voltage and other parameters for each GPU separate?

        • Grant Southey

          As per the settings from this article point 6 above or

          @https://disqus.com/by/kkourmousis/ below 🙂 I am appreciative of both 🙂

          ( I did find I had to have a card plugged into the Main GPU and -asm set as per the readme )

  • Cesar Augusto

    could this bios work for a XfX 580 8gb GTR (hynix memory) card as well or does it have to be the same brand (a saphire)?

  • Zulekha

    Hoping someone can please help! The motherboard we are using is the Asrock z270 Killer SLI

    We have tried using windows and ethos but are having the following issue:

     

    We are able to mine with 4 cards no problem but the moment we install the 5th carad it bombs out two cards and only three become available

     

    The error we are getting is insufficient system resource

    Not sure if its the motherboard?

    • Daniel Rubio

      You must go in to tje bios and enabel 4GAbove….

      • drx3brun

        Also make sure you patch the bios to the newest version.

  • Daniel Rubio

    Anybody a idea to becomme the msi rx 580 gamming x 8gb with hynix faster?

    I test every strip…1500 to 2000 1625 to 2000 an up to 2250 ,1750 to 2000 and so on custem mixes….but this card want go higher…????

    • SteveG

      so far with msi rx580 gamingx 8gb card (Hynix memory), I’ve only been able to get a slight increase by copying 2:1750 to 2:2000. With that change alone, I increased from 22.4mh/s to 25.3mh/s. I would love to get at least 27mh/s out of them.. anyone else able to do better? please share.

      • Haythim Nouira

        copy 2:1725 to 2000 2250 and coreclock 1250 memoclock 2080 you will get 26,3 mhz.
        this my problem too i can’t go more, and if i set memoryclock more than 2080 pc crash!

        • Haythim Nouira

          Ciprian any suggestion please?

          • Hi, have you tried copying from 1:1750 to 2000 and 2250 ?

          • Haythim Nouira

            hi, but this modification to copy 1:1750 to…. it’s not for samsung memory? i have hynix memory, it’s not copy from 2:1750 to….. ? and for my timing strip i have just 1:1750 and 1:2000 after that 2:400 2:….. i don’t have 1:2250 thanks.

  • Jaro

    Hi Just would like to know if I can use the same way for the RX580 Nitro+ LIMITED EDITION? I’ve just bought 2 of these, but not certain if I can use it, from what I know the only difference is one bios and the colors isn’t it?

    • drx3brun

      I tested both images on LE version, there are no differences in results from regular Nitro+.

      • Jaro

        Nice thanks for the info! I bought the limited just cause it was the only one available for few minutes ?

        • drx3brun

          I think there is no difference aside from the flashy vents.

          • Jaro

            I confirm, no difference~

  • Bdon

    So I missed Step 3 and accidentally flashed over the main BIOS. The card still works fine but I’m having trouble flashing anything on top of it now. ATIWinflash says “VBIOS image not found.”

    Does anyone have any advice on how to fix this? I saved both stock ROMs successfully (both 512kb and 256kb GPU-Z versions) nothing is working for me atm. Windows 7 64-bit Sapphire Nitro+ 570 4GB Hynix.

  • E_

    I have the XFX RX 580 8GB with Hynix memory. I imagine that it’s probably not a good idea to flash this BIOS on it?

    Forgive my ignorance, but in theory I should be able to achieve the same result just using Trixx if its going to work, right? It feels safer to play with it that way first before locking anything in the BIOS.

    • Nope, this wont work with your card, try to manually modify the bios of your card comparing the differences with this one.

      • E_

        Thank you Ciprian. I applied the settings using both Trixx and the Start.bat command for Claymore. My power usage dropped from ~135W to ~75W (reporting from GPU_Z), but my hashrate dropped from ~22.5 to ~19.2GHs. So after a lot of playing around, I ended up just lowering the mV by 150 (Trixx). This maintained the ~22.5GHs but dropped the power usage to ~90W.

        I haven’t tried the dual BIOS install yet. I’ll try that this weekend. Hopefully that will help increase the hashrate a bit. So far nothing I do will increase the hashrate past 22.5GHs… which is a bummer considering that 1stminingrig was able to achieve ~30.1GHs on a similar card… So hard to get ahold of these cards right now, was just happy to get this one. :-/

  • Inf0Men

    Yay finaly i could get my Gigabyte Radeon Rx 580 Gaming 4GB Hynix memory.to 31.5 Mh/s using 1500 timings mem clock to 2180 and core clock to 1240, temp stable at 63-65C at 70% fan speed with -50 undervolt using 125W.

  • Maguary

    Awesome vbios, but is there one for Samsung memory?

    • Didnt got a card with Samsung memory yet 🙁

  • drx3brun

    Thanks for the great post! Is there an easy way to modify those images in order to undervolt the cards? I am using this images under Linux and there is no easy way to change the voltage and the cards are using over 200W with those settings. Claymore undervolting doesn’t work under Linux (as stated in the docs). The author suggest the only way to achieve that is to mod the bios. Thanks for help!

    • Yeah.. the undervolt can be done via bios modification directly.

      • drx3brun

        Which software should I use to edit those images. Polaris Bios Editor?

      • drx3brun

        Any chance you could provide some information on where to find some tips/guides on that? Having hard time to figure it out, as there seem to be no straightforward guide.

  • Diki Arch

    Hi, Ciprian.
    I would to ask you about Nitro+ card. That card have 1x8pin +1x6pin power Connector. Do you use only 1x8pin? or extra 1x6pin must powered too?
    Thanks.

    • Hi @dikiarch:disqus , i use the 8 pin connector only.

  • RobJ

    hey CiprianV thanks heaps for the guide helped me out massivly i have run into a problem i had 4 cards hashing at 30 with cclock 1130 -mclock 2150 but i changed cclock to 1150 was working fine at 30.2 but now for some reason it was crashing i reinstalled GPU drivers its working fine but 3 cards are hashing at 28 and 1 is at 30 do you know of a fix?

    • RobJ

      all good CiprianV re flashed the bios and they are all running at 30Mh/s is the 1150 alright to run on and i was just unlucky?

  • Adrien Forest

    Hello, i need some help from you guys or Ciprian, i have a HX1200i and H81 pro btc r2.0 and ofc RX 580 nitro+ 8gb.
    First of all when i saw that RX 580 needed 8 + 6 pin i was frustated because the hx1200 have not really 8×8 pins but 4 cable 6+2 x2. I saw too late in this thread that you could just plug the 8 pins (i tried with other cable from other psu but i fried my H81… Because those cable where indeed 6+1 pin gpu side but only 6 pin psu side. I fucked up hard on this one 🙂 )

    First question :

    Why dis you removed the hx1200i from your post about best 2017 hardware ?

    Second question:

    As i saw in comments you can just plug the 8 pins on rx 580, But can we use the hx1200i cables that are doubled? I mean one cable for two cards ? 6+1 and 6+1

    Finally:

    What is the best mobo beside h81 for socket 1150 ?

    Best regards guys and if you can help me out i will be happy as larry !

    • Hello @adrienforest:disqus, The HX1200i was recommended for the rx400 series, since the 500s consume a bit more power i decided to switch the psu with 1300w from evga which is better because it also have more pcie cables (but this is not a problem).

      Since the HX1200i have only 4 PCIe cables splited, you can power two GPUs with one cable each and the rest of four cards with two pcie cables, two GPUs per cable.

      Attach the 8 pin connector only, it will work just fine.

      Very important is to downclock to 1130 and undervolt the cards as much as you can like directly from claymore: -cclock 1130 -mclock 2150 -cvddc 850 -mvddc 850

      • Dendy Oktavian

        evga 1300w not available in my country… so i use 2x evga 750w T_T

    Thank you for your time!

  • WMK

    Thanks for this great tutorial. I’ve managed to successfully flash the cards, they are all stable at 28.3MH/s.

    The only problem I’ve encountered is that temperature is NOT displayed, neither in TRIXX, Afterburner or GPUz.

    Any idea how to get the temps to be displayed properly? Thanks!

    • Grant Southey

      I found I had to have a monitor connector (DVI) attached to the main gpu (AMD one).

      • WMK

        Thank you, this indeed worked. After connecting a display through HDMI to the main GPU temps were displayed properly.

    Hi guys
    I’ve got 12 x Safire RX 580 Nitro 8GB cards on order for myself and a friend. They’ll be in the shop in 8 days.
    I’ve got soooo much to learn but my main concern atm is the brand of ram on the cards. It looks like it should be either Samsung or Hynix from what I’ve been reading. Is that so and if so is there a code on the packaging or card that will tell me before I pay for them.
    Thanks in advance for any information

    Hi, I’ve done this and am getting 30Mh/s at low power. Had a few stability issues when claremore closes or I shutdown Windows 10. It will just hang with a coloured or black screen and fail to shut down. This was solid on the latest drivers with claymore 9.4. Wondering if this is drivers or claymore related, any help would be welcome.

      Hi eltimmo, I have the same problem with two Sapphire nitro+ rx 580 8gb. I start mining but after some random time my rig freezes and I have a blueish screen. (not the blue screen of death)
      Do you have any suggestions? I’ve followed all the steps correctly. 🙁

      • eltimmo

        I haven’t fixed it, I think it will be driver related. Its caused by all the animation and crap on the start menu. As it’s stable for mining, I just use the command prompt to do stuff. It’s been up for weeks with no issues

  • Juan M.

    I have follow this steps and cannot find a way to overclock the GPU. I have flash the GPU bios and I know they work because I tried it on a friend rig and they hash 30M/Hs. How ever when I connected to my rig is only giving me 27 M/Hs and I cannot find a way overclock and under volt. If I have my rig on for more then 30 min it shut down b/c I believe it consume more power then the PSU is capable on providing. Another issue is that when it’s mining a temp status usually show up every once in a while but right now when I start Claymore’s it does not show the temperature. I cannot find a way to determine at what temperature the card are running at. I tried installing trixx that it still does not show me the temperature of the card and cannot overclock which this program.

    Hardware the I current have
    EVGA Supernova 1300 G2
    h81 pro btc r2.0
    Sapphire Radeon NITRO+ RX 580 8GB GDDR5
    SanDisk SSD PLUS 120GB Solid State
    Kingston HyperX FURY 4GB
    Intel Celeron G1840 Processor – BX80646G1840

    When I connected everything I ran into a problem which was that I could not find a way to boot the OS using the GPU. The way that I solve this issue was by going into the bios and enable the on-board card as primary card. Then I was able to install the driver for the GPU’s by using the embedded graphics card on the board. I have tried enabling external graphics cards as primary but I still get stuck in a black screen if I do that. I’m that sure if that causing this problem.
    also I’m now getting this error when I start the miner
    GPU5, OpenCL error -4 (0) – cannot create DAG on GPU
    GPU4, OpenCL error -4 (0) – cannot create DAG on GPU
    GPU1, OpenCL error -4 (0) – cannot create DAG on GPU

    Very promising results here!

    I, on the other hand, have an Asus Rx580 Dual OC 8GB with Samsung memory. I have custom ROM and used Trixx to get 1260/2025/-100mV but it only gets me 28.3 Mh/s tops with no memory errors. GPU-Z says it’s consuming ~120w of power.

    Help! I want to get that mythical 30-31Mh/s too! 🙁

    • The hashrate maybe low also because of dag epoch, have you tried to test adding -benchmark 1 ?

        other post didn’t seem to come through.. will try that, however – the other two cards I have with the 512k bios currently get 31 each at 900mv consistently.. not sure if the voltage or memory straps are wrong on the 256k bios.. sent one is original.

  • Luis Gimenez

    Hi and thx so much for your guide….I read all and have only one question,

    it is ONLY für Sapphire or also for Powercolor RedDevil for example?

    I have RX580 8Giga HYX but not von Sapphire, only from Powercolor, but normal the have the same Memory from HYX, or?? (in these case)
    Thanks another time

    • Hi, yes only for sapphire, this model only.

  • Bossman

    Hello everybody, i have been reading whole thread and i find it very inspiring and helpfull. I have been able to get from RX 580 Nitro+ 8GB (11265-01-20G) Hynix memory such stats:

    EthDcrMiner (solo mining)
    28,700 – 29,100 taking 78-79 wats
    30,500 88-90 wats, got same mh results with dualmining ETH+DCR but mining uses about 103-112 wat

    Wattage usage is from GPU-z since i am waiting for my wall meter.

    Undervoltage and cclock/mclock done only via EthDcrMiner commandline
    I have done bios mod and copied 3straps from V1 bios to 1750, 2000, 2200 from this post. I am on newest AMD drivers, Windows 10

    What do you think are thoose results good ?

    EDIT:
    There are two matters that are problem for me. After i upgraded bios or reinstalled drivers now i don’t recall what was first I can’t use Stixx, AMD Wattman or MsiAfterburner in regards to setting different mem and gpu clocks, cant even undervolt. In the second i press apply it always hang. Does anyone know what could be wrong ?

    EDIT2:
    So i have purchased ethOS since i know well Linux. But i read that i can’t undervolt RX580, and core clock and memory clock does not change mh at all when i experimentate (only 3memory straps bios mod had helped in anything there).

    I have heard that this changes can be done only via bios Mod. Does anyone have done it via bios or know any FAQ how to do it ?.

    I like to use ethOS bcoz there are some advantages for me to use it, for example power usage is smaller than on Windows when i compare same settings.

    Sorry for such long post, i hope it will find his answers 🙂

    • Hey @disqus_dIHgUFJx4n:disqus , have you tried to undervolt directly from miner, on windows? like -cclock 1150 -mclock 2150 -cvddc 850 -mvddc 850, if system crashes change from 850 to 875 or 900, play with the settings till you find the sweet spot for each GPU, most people think that if the gpu is the same model, also should reach the same overclock… THAT IS SO WRONG!! Best way to get the best of your GPUs is to test one by one.. 🙂

      • Luis Gimenez

        How i can change the voltage for each grafic card? In the claymore are the voltage value for all cards:( thx

  • Mike

    Can i flash this V2 Bios into my MSI Armor RX 580 8gb Hynix?

  • Minh Dieu

    Can someone please share with me a rom that can do 31 hash rate. i have rx 580 nitro oc 8gb hynix thankyou in advanced.

    • This is the best you can get 🙂 also consider the hashrate drop on ethereum for rx series.

  • Adrián

    Can this work for the 4gb model? is the same but only with 4gb

  • sam

    Hi Can i use These bios Files for 4 Gb version

  • Peter

    @cipr@ciprianpt:disqus , Hope you can help. Desperate

    I’ve search far and wide online but can’t get any help on Sapphire nitro+ 570 8gb Hynix gpu’s.

    I got 21mh/s on stock and now managed to get it up to 24mh/s by copying 1500 straps and Afterburner but not having much luck. Been a week of struggle. Hope you can help

    • Copy 1750 to higher.. it will work 🙂

      • Peter

        Thank you very much for your reply. But i’ve tried and only getting 22mh/s but with 1500 i at least get 24mh/s. Thats the best. I see a few people with these cards on different websites and no one can get more than 24mh/s.

    • Joe Mc

      Same problem here, I simply cannot get better than 23.x on ETH only, 22.5 on dual ETH/SC. Changing the mem clock has zero effect. Why would that be?

  • Brj Ng

    I have little issue with my rig Sapphire NItro+(5 GPUs), I am using Asus Z270-A, Intel Pentium, G4400 (LGA1151), 8G DDR4, Corsair 120gSSD, 1000Watt PSU.
    I got all up and running with all 5 cards show in the devices manager. When start Ethereum software it shows 4 cards running at 22Mh/z and 1 card (GPU0) running at 4.8Mhz. If I run 1 card at a time then all the cards showed 22Mhz. Put all the card back then 1 card at GPU0 showing 4.5MHz, please help me how to troubleshoot this issues.
    I did try to user version 1 flash file but I also get the error “Cannot erase ROM” something like that.
    Please help
    Thanks so much

  • Daniel Zet

    is someone using this bios on simple mining OS? i am using power stage 3 and 1175/2175. stable about 24h then restarts…. 28,6mh on DAG#136. how about you guys? 7 x rx580nitro = 1115W

    • erlendfr

      To me that sounds like your core has just to litle power. Try bringing it up 10-20 mV.

      You can also try tro bring the core clock abit more down to about 1130-50.

      Heat can ofc be a problem aswell, I try to keep my cards around 50-60 C. Should not generate that much noice if your eth only mining.

      Also the mem voltage shouldnt be lower then 0.9mV ,the memory dosent really affect your power consumption that much anyways.

      Hope it helps!

      See below screen shots taken from my SMOS. For now it is 3x Sapphire Radeon Nitro+ RX580 8GB (HYNIX) with own moded BIOS (2:1750 –> 2:1750, 2:2000, 2:2250 timings). https://uploads.disquscdn.com/images/b4ad2d3696c1f8a6cda52942222be675b5de4016e65b6d807d39fcac8aa20233.png https://uploads.disquscdn.com/images/cf37c08607d9e5c297da8acc0687f60583b9efb3adc5142426792c1a5207dd67.png

      Stable 29.1MH/s since 2 days.

      • Daniel Zet

        Hi Mariusz and thank you for your reply.
        What power consumption do you get with this Settings.

        I have actually with DAG 138

        1250 2150 (3) 199,5 Mh/s 1113 W
        1150 2150 (2) 193,2 Mh/s 1045 W
        1175 2175 (2) 196,5 Mh/s

      • Daniel Zet

        Hi Mariusz and thaks for your reply.
        What power consumption do you get with this Settings ?

        i have 7x RX580 Nitro Hynix still with this modded bios and :
        GPU MEM HASH POWER
        1250 2150 (3) 199,5 Mh/s 1113 W
        1150 2150 (2) 193,2 Mh/s 1045 W
        1175 2175 (2) 196,5 Mh/s 1060 W

        but I could not get it working stable on memory clock 2200 and more .. also on power stage 4. That’s why I’m using max 2175 mem clk.

        but maybe with my original modded bios (i have it already on bios “Position 2” flashed 🙂 ….. did you also tried power stage 3 with the same clocks? I am afraid that with your Settings and powerstage 4 I will be need 1300W !!

  • erlendfr

    Hi!

    Seen alot of ppl having issues with geting some juice, so I hoped I could be a helping hand. This is a dual mining setup, but should work fine with single mining aswell.

    SapphireRX580+Nitro(Hynix)MOD.rom —–> https://goo.gl/6srHa2

    My results so far: ETH: GPU 29.423 Mh/s – DCR: GPU0 970.964 Mh/s

    These are my seting for the RX580 Nitro+ 8GB Hynix mem.

    Use at your own risk ofc.

    Using the ClayMore Dual miner 9.7, with these setings in the run bat:

    -etha 0 -dcri 33 -r 60 -tstop 85 -tt 65 -fanmin 40 -fanmax 100 -cclock 1200 -mclock 2250 -cvddc 970 -mvddc 950

    (This will: Set your miner difficulty. 60 min miner reset timer. Temperature
    miner stop 85 C. Temp target 65C, Min fan 40%, Max fan 100%, Core clock
    200 MHz. Memory clock 2250 MHz. Core volt 970 mV, Memory volt 950
    mV.)

    * I dont use MSI afterburner, Trixx or any other program for anything but the -10%
    power limit.
    * This is ofc in addition to the minig pool and wallet setings.
    * All commands in your run bat has to be in one line of text.
    * I run a 60 min miner restart command, as I see a tendency of speed droping when
    the miner works for too long.

    Coppy/paste of my claymore 9.7 dual miner log:

    18:24:10:475 3d4 ETH – Total Speed: 147.931 Mh/s, Total Shares: 222, Rejected: 0, Time: 01:00

      can you share you link download file again , your link dead

    • Ari Sudana

      Hy erlendfr, thanks for you explain your mod bios, that so great, i was test your bios and get same hashrate, but i want ask, what for we need make miner reset every 60 min?,that’s effect for speed?,

      • erlendfr

        I have observed that the hash rate
        seems to drop abit (1-2 M/hash) when the miner has been runing non stop for hours or days.

        There is no problem to increase the timer, or remove it all together.

    • Gunner

      How can you put -10% in gpuz ? thank you

      • erlendfr

        You dont 🙂 For that you can use afterburner or Trixx etc.

        There is a command for it in claymore aswell, you can find it in the “README.TXT” file in the claymore Main folder.

        • Gunner

          Ok, thank you, but did you notice gpu memory errors with this config ?

          • erlendfr

            So far its stable and error free.

            But as known, there are small differances between GPU’s.

            You should have some leaway on the mem voltage, but you can set it to 1000mV if you are geting errors.

            If that dosent help, pull back the mclock and cclock abit. You shouldnt notice to much of a performance drop.

            It dose take abit of time to fine tune the system.

            In fact you should do these steps for each GPU, and not set all at once to get max performance with these timings, or any others for that mather.

          • Gunner

            ok, by the way, thank you for this very helpful informations. Can you tell if my process to set my cards is good : Plug 1 card, lunch claymore with your settings. Plug the second card(keep the first plugged), lunch claymore with your settings and so on. Am I wrong or its the good way to do it ? If not, can you resume the process.

            still thank you !

          • erlendfr

            You dont have to unplug your cards, its abit if extra work tuning single cards with the claymore config files. But if you read through the read me file in the claymore main folder, its well explaned.

            Im not 100% if I remember correct, but, if you have 4 gpu’s, you would set card number two core voltage with: -cvddc 970 0,1,0,0

            card 1: 1,0,0,0 card 2: 0,1,0,0 etc.

            You can select two or more with:

            Card 1&2: 1,1,0,0 Card 2,3&4: 0,1,1,1 etc you will get the point.

            So I would create a config file for every card, and when I’m done, coppy paste the configs in to a main file.

            Hope I explaned it well enough 🙂

          • Gunner

            well explaned, thank you. But it seems like the settings dont apply to my gpu, maybe driver or something like that. Can I overclock all of my cards when I’m plugged into my MB ?

      • Mit –
        It looks like you need to update the GPU core to 1200 and GPU memory to 2250. Your power draw also looks high. Add this to your start.bat to set all three:
        -cclock 1200 -mclock 2250 -cvddc 970 -mvddc 950

      • erlendfr

        As someone else pointer out, it dosent look like the oc settings have kicked in. Recheck your config file.

    • Bert

      Hey, I used your rom and so far I am really happy, I get around 28-29 MH 🙂

      However, strangely my memory clock does not stay at a constant 2200 Mhz. It seems to be jumping between 1000 Mhz and 2200 every couple seconds. Do you have any idea why?

        Did you manage to sort out any solution. After flashing to Bios off erlendfr, I also seen oscillation of memory clock b/w 2250 and 1000. its not just that. Hashing also oscillated between ^~29 and 14 (halved).

        need help

        Using Sapphire RX580 N+

        PS (Running into all sort of issues.
        0. Core Clock & Memory, both showing Zero.
        1. Trix wont work for me, whatever I put in by using the slider, cannot verify thru GPU-z. Only using for Fanspeed
        2. Afterburner cannot specify at all.

        formatted pc to refresh install everything. I am in deep S***t.)

        • Bert

          I haven’t found any solution just yet, but I think it has to do with ULPS -> AMD power management. It cuts the power when it thinks the GPU is idle and boosts again for work. You can turn that of with regedit (google it) and in Trixx, but it changed nothing for me. I think I will have to re-install drivers perhaps it works then. For now, I set up my miner with ubuntu because I wanted to check if it still happens there. In Ubuntu I have stable clock and also stable hashing rates, but they are somewhat lower than my max on windows even with the same OC parameters

          • Bert

            I think I figured it out. If you define the clock speed, voltage, fan speed etc. in the start.bat file, there seems to be a conflict with AMDs wattman. That causes the fluctuation. What worked for me is to remove all those parameters and go with -esm 0 -estale 0 -mode 1 -asm 1 -etha 0 -dcri 17 only in my start.bat (after the usual eth address, pool etc.). Voltage, Fan speed and clocks I configured in wattman in the AMD Radeon Settings, Gaming, Global WattMan settings.

          • somali

            Worked for me too.
            But problem with the Wattman is that after an every reboot, have to reconfigure the Clock and Memory (imagine you have a 13 GPRUs’ rig) or is there a way to save the profile and autoload it everytime the PC reboots.

            Providing the clock parameters in the Start.bat wasn’t bad after all since it takes care of re-configuring part probably we need to recode?

          • Bert

            AFAIK there is no way to save settings in wattman, yet. :-/ it’s a pain in the ass to be honest and I am “happy” that I only have to deal with 2 GPUs. I don’t have to enter the values after every reboot, though. only if the system crashes. wattman then goes back to default settings. my advice would be: try to find a stable configuration and just leave it running^^

          • This worked for m too, if I tried OC from claymore settings was unstable and the memory clock fluctuated. Ended up using Trixx instead of wattman. 29-30 Mhs stable at around 110W from GPU.
            I wonder if we can put all settings in the BIOS, seems possible.

          • Bert

            How did you make trixx work? Whatever I try, I can’t control my GPUs with that -.- neither does msi afterburner work for me. only wattman

          • Not sure, it’s very odd, some settings seem to work for me with Trixx but others not. Memory Clock and Core Clock is putting +100 on GPU-Z of what I input. Voltage limit display fine, undervolt seems to be fine too. I’ll try wattman to see if I can do better fine tunning

    • Slavko Klincov

      Hallo there, thanks a lot for eveything here.i use LUBUNTU 16.04. and i
      buyed 2 of the nitro+ RX580 Special Edition 8GB, 256 bit,(with blue
      lights inside/Pretty cool looking :)) and at the beginning i only had
      21 MGH/s on claymore 9.7. eth only! Than i tried yours @erlendfr:disqus and it didn´t work for me, just 27 mh/s ! now, big thanks to Ashley Forrest , i have 28,5.
      so, is there any possibility to get to the magic 30 MH/s ?
      I would realy like to get those 30 and of course to donate for help?
      i have some sort of feeling that, when i change clock and mclock that there is no increase or change of mh/s!
      Ciprian V. I realy don´t know why, but yours didn´t also work out, well it worked but i am just getting with V1 26 / with V2 27 mhashes.
      Ashley Forrest thank you a lot again, i realy don´t understand, what´s the difference here, but the best until yet.

      • erlendfr

        I’m sorry, I havent tried mining with any Linux distro, so my knowlage is limited. Tho I do know there. are issues with the drivers, the newest once to be spesific. For starters try googleing for the correct drivers to use.

        If that dosent help, start from scratch and build your own oc setnings.

        I would suggest starting from cclock 1100, cvolt 850, memclock 2000, memvolt 1000, and step up memclock to your satisfaction.

        Do remember all these setnings are intertwined, so if your geting 29mhs at 2200mhz memclock, increasing coreclock by 10mhz can give a bigger bumb in hashrate the higher mem clock. Same goes for voltage aswell.

        All I can say is, experiment. Make small addjustments and see what the resulting outcome is. If you lose hash on clock increase, try uping the voltage etc. You will figurer it out eventually ☺️

        • Slavko Klincov

          ok, i´ll try uping the voltage, thank you 🙂
          Do you know, what settings claymore use, when you don´t set cclock and mclock in config ?

      so i get around 27.500 ETH and DCR around 900 is there a way to improve or better, why do you get 29 mh/s with the same settings any suggestions?

  • Brj Ng

    I am around 28.5Mh to 28.8Mh ..never reach 29 or 30 and the power is so huge 130w-140w each gpu? anyone have the modded bios to share? I need 256k bios version for Sapphire Nitro+ RX 580, 8g Hynix memory …thanks

    • erlendfr

      If you are runing the claymore dual miner you can add:

      -fanmin 40 -fanmax 100 -cclock 1200 -mclock 2250 -cvddc 970 -mvddc 950

      I prefer to use the config file of the claymore miner, as I get alot more stable results from that then Afterburner/Trixx etc.

      Thats my setings for the Sapphire RX580 for dual mining, and keeps me at about 100-110W per card.

      My ~ avg. rates: ETH: GPU 29.423 Mh/s – DCR: GPU0 970.964 Mh/s

      If you just want to mine for ETH, I would go down to ~ -cclock 1130 and addjust the -cvddc down as far as its stable. You should at least get down to about 80-90 watts per card easly.

      But check out my post a bit down the list. Sort by newst should bring it up abit.

      The bios isnt anything ground breaking, just the standard 2:1750 –> 2:1750, 2:2000, 2:2250 timings.

  • Robert Ilić

    Hi, have a 6x sapphire Rx 580 nitro+ 4gb/hynix and whatever i do cant get over 24Mh/s on any card, did not tried any of offered VGA BIOS because is not 100% same as on my cards. i did flashed VGA BIOS manualy. strange is that even msi afterburner or sapphire trixx not give any result or claymore attributes. Its like cards are locked for overclock.

    • Hi, What is the driver version ?

      • Robert Ilić

        latest 17.7.2, i tried combo also the same efect

    • Slavko Klincov

      try to copy from 1:1600 to end, (last 4 with 777) worked for me for 28 mh/s.
      Still not getting to the 30. (for Samsung Memory)

  • donanimcetin

    hi. i need mod bios for sapphire rx570 nitro+ oc 4 gb with Hynix memory. if you have share or send me please. thanks. donanimcetin@gmail.com

  • Geniom

    Hi,
    Thanks you so much for this detailed tutorial!
    What if you have a mixed cards mining rig ? In my case I have both rx 580 and r9 380x. It would not work to set the overclock via claymore since it would apply the same settings on every GPU in the rig correct ? If so, what would be a solution for a complete optimization ?
    Thanks for the help!

  • Illan Zed

    I’m using the V1 bios with core@1250, vram@2250 and -100mv
    Performance is awesome (31,5 ETH solo or 30,2 eth+sia)

    But I draw 1600+ watt at the wall… Seems way too much… Any suggestions ?

  • Slavko Klincov

    Hallo there guys, you are realy amazing with all your posts and realy thank you.
    I am using LUBUNTU 16.04. and i buyed 2 of the nitro+ RX580 Special Edition 8GB, 256 bit,(with blue lights inside/Pretty cool looking :)) and at the beginning i only had 21 MGH/s on claymore 9.7. eth only! now, fuckin big thanks to @disqus_DjrSVzMOWI:disqus , i have 28,5 with 1200/2150 clocks, and 970/950.cv/mc!
    so guys, is there any possibility to get to the magic 30 MH/s ?
    I would realy like to get those 30 and of course to donate for help?
    i have some sort of feeling that, when i change clock and mclock that there is no increase or change of mh/s!

  • Ionescu Doru Marian

    Hello !
    For 580 nitro + 8gb.
    I did everything I needed, and finally I did not manage to write the modded hinyx bios.
    1- bios backups,,,,ok
    2- drivers overwrited and installed,,,,,ok
    3- atiflash with modded bios in the same folder,,,,ok
    4- writing new bios,,,,,FAILED ( CANNOT ERASE ROM )
    Somewhere, something is wrong.

    Do you want end can, help me ?
    Can you send me rom, which runs you 30 MH Eth, and could be writen

    • Slavko Klincov

      Downlaod polaris bios editor from jaschaknack, should work.
      you just are using 256bit for 512bit or in the other way.

    • Mariusz Machnio

      I had the same issue for same card. Finally, I did BIOS modding by myself, just changeg 2:1750 –> 2:1750, 2:2000, 2:2250 timings. Now I have stable 29.1MH/s since a 2 days.

  • exxis

    Hey there one question about the RX580, everything is working the last days, i build a testrig to see if and how everything is working and upgrade later, currently iam running one Sapphiere RX580 Nitro+ (not the limited edition) with you bios, it has the hynx memory so should be no difference.
    This morning the pc crashed and restarted (its an old AMD A6 Series A6-5400K 8 GB DDR3 and a 700W PSU) after the restart i tried to check what caused this but after opening the bluescreenviewer it crashed again.
    Could this be because of the old CPU or some error with the GPU and the drivers? As i said for the last few days i had no problem, currently after i waited a few minutes its working again.
    The GPU has 53°C at full load, so the temps should be no problem,

  • Robert Ilić

    ok ppl, just wanna say that Sapphire Nitro+ RX580/4gb/Hynix is a hell for mining, lost over 3 weeks, and NO positive result for mining, just wanna share with u what i have tried:
    1. MB bios flash done it (Biostar TB250-BTC) 710 ver, miner mode on
    2. Win10+ati 17.7.2 driver (the onlyone who can see 6 cards)
    3. VGA Bios flash (couple mods NO EFFECT with any know mod, lost so many hrs)
    problem is that whatever u do with the vga bios, driver (tried 20 or so) not SEE IT,
    in some mod’s mb wont boot at all, need IGFX maste for it.
    4. For vga bios flash used polaris v1.4 and 1.5 for RX5xx cards, change 1:1500 to
    1:2000, and 2:1500 to 2:2000, and make same combo, left 1 stipes untouched just 2
    5. For undevolt and overclock used MSI afterburner (useless), trixx (useless) and with amd watman partial succsess.
    6. With a claymore miner, give some parameters for overclock and undervolt no result
    just got some results on vent and temp stability.

    The major problem is HOW to make driver to see vga bios mod, actualy modded, used atikpatcher, with no efect, used it wit combo of any driver ppl tell me that will work still no efect.
    If anyone have a similar problem or the same and have a solution for it please explain here HOW TO MAKE IT TO WORK, thx for reading this 🙂

    • Hey Robert, I made this card to mine 30.5 Mh/s on 130 dag test.. i will also post a tutorial soon 🙂 btw i am still using the combined/mixed drivers.

      • Robert Ilić

        ok thx m8, cant w8 for it, bit down last couple days here, donno what to do to make this cards to work better, cheers !

  • Az

  • jns coaching

    Dose it work for RX580 4GB?
    Thanks

  • Eliot Mason

    Will this work for the Special Edition Graphics card also?

  • Ariel Orozco
  • Gonza Barberis

    Hi, i had no problem modding my rx580 strixx. But with the nitro+ rx580 8gb I get 21mhs out of the box and when I try to modd the bios this is what the timming values look like and Im stuck here! https://uploads.disquscdn.com/images/1168ec6b293afb6809316306f26ce7446ed70268758a33ae830a1f2ef1d11c83.jpg

    • Rodrigo

      use polaris bios editor 1.6

  • y. emre

    hi!
    does it work for SAPPHIRE RX 580 NITRO+ 8GB SPECIAL EDITION
    (turquoise one) ?
    best regards.

    • Nope..

      • y. emre

        Thanks for reply Ciprian..thats sad to hear 🙁 I am about to buy 12 of them for very very good price, do you know any rom or similar mod to hit 27+ mh/s for ethereum? Thanks in advance..

        • Only if you edit their original bios 🙂

  • Vlad

    Hi,

    Any chance we can get a tutorial/rom for the rx 580 nitro+ Elpida memory?

    Thanks!

    • I only had Samsung and Hynix :/

      • Vlad

        No worries, mate! Cheers!
        I guess I have to figure it out the hard way. Trial and error 🙂
        Anything I should be aware of so I don’t brick my card? 😀

        • Send me the rom 🙂

          • Vlad

            It’s an Sapphire 580 Nitro+ Elpida. I’ve already copied the 1750 straps to 2000. Do i need to bother about the other straps if I will be running it at 2000+.

            I’m just trying to get the basics of it. Should I run it at much lower frequency and copy the other straps? And how do I need to change the GPU frequency in regards to the vram frequency?

            Thanks!
            Vlad

  • Brad Rands

    I’m about to pull the trigger on components for my first mining rig, and wonder the dual mining performance & power consumption difference from the sapphire nitro+ in 4gb and 8gb, anyone have experience testing both?

  • disqus_4HpwpsPdE5

    Hi everyone
    I’m in need of help. I have myself 4 x VisionTek RX 580 8G OC (hynix). I’ve tried several different BIOS mods found on this site but the best I can achieve is 25Mh/s. There seems to be nobody here that has my exact graphic card. Any help to 29+Mh/s would be greatly appreciated!

    • Have you tried modifying the original bios ?

      • disqus_4HpwpsPdE5

        Yes. I couldn’t flash your V1 or V2 bios mods so I opened them, noted the changes made and created my own. Those changes got it from 21Mh/s to max 25. I tried with firmware 17.7.2 as well as 17.9.1. Right now I only have 1 of the video cards connected. Please let me know if you need more info. Appreciate the assistance

        • hmm.. what timings did you used?

          • disqus_4HpwpsPdE5

            -cclock 1130 -mclock 2150 and -cclock 1150 -mclock 2150
            tested on both of your V1 and V2 bios mods

            GPU only draw is stable at 62W. Maybe more juice will do the trick? Sorry I am very new at this so I’m not sure what settings I need to change.

          • Have you also tried with higher mclock ? max is 2250

          • disqus_4HpwpsPdE5

            Yes but unfortunately it didn’t make a difference in speed and it crashed the pc. I’ve tried adjusting the mclock and gpu clock through claymore as well as through Trixx with no luck. I also started from scratch using 2 brand new Visiontek rx580 8G OC GPUs. I’m almost convinced that these Visiontek cards cannot achieve 29+Mhs

          • Hmm.. can you share gpu-z screenshots?

          • Mehmet Budak

            hi man i read you on forum i yesterday start for mining i buyed 1070 1 card but it 612 usd and mhs 31 with oc i saw here people doing with it rx 470 /580 but it look hard for me to moded i dont know much tecnical and this rx more cheaper what i can do can you give me idea becous i want make a ring

          • AMD rig is cheaper than Nvidia, also AMD video cards performs better in dual mining. I personally prefer AMD RX580 series

  • Jonathan H.

    Hi !

    First of all, I would like to thank you for your great tutorials !

    When this post was created, the drivers version to combine were :

    Combined AMD Drivers 16.11.5 + 17.5.1

    Today, the driver versions are updated : Crimson ReLive Edition 17.7.2 and 17.9.1

    Should I combine these 2 drivers now ?

    Thank you !
