Ledger Wallet protects your bitcoins

Here it is guys, the beast, the best of, the Sapphire Nitro+ RX 580 8GB Limited Edition mining peformance test and review.

First of all i must say that this is one of the best GPU i ever tested. It is STABLE, RUN COOL, BEST HASHRATE and is HUGE!!!

As my previous test for the PULSE version i did the same tests, same practice. I tested it with Ethereum + Decred, Siacoin, LBRY Credits and PascalCoin also Zcash (Equihash), Monero (CryptoNight) and Nicehash.

Stock performance, mining hashrate and power consumption!

POWER CONSUMPTION FOR SYSTEM IS AROUND 50W AND 60W

Sapphire Nitro+ RX 580 8GB Limited Edition Mining Performance Review

 

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!

For this card the bios is already switched to NON OC version (HDMI SIDE), do this:

  • first start the pc with his default bios position (non oc, hdmi side)
  • once windows is booted switch jumer to the other side and restart the rig
  • now check the following steps
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

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

Here are my results with this BIOS rom

    Hello Criprian!
    Thank you very much for this beautiful tutorials!
    Quick question….
    Is it possible to mix RX470/480 with RX570/580?
    The diffences are only “Combined AMD Drivers” from the old series
    Thanks!

    • Tim Bos

      You can mix it, but you need to set different mem and GPU settings for each card in claymore.

      • Sim

        Thanks! And what about the drivers?

  • Marco Poles

    Hi Ciprian, do you plan to create a post also for RX580 with samsung memory?
    I have also another questions:
    1) on RX580 nitro+ LE there is bios switch. Is it used to select 2 type of bios, one standard and one auxiliary?
    2) I modified my RX580 nitro+ LE bios (only auxiliary one coping 1750 timing to 2000 and 2250). When I try to install crimson 17.5.2 the GPU is not recognized on both bios switch position. Why? I thought to have install problem only with bios switch on auxiliary position.

    My rig has 4 RX 480 and 2 RX580 with windows 10. But at the moment I’m not able to begin the mining. I tried to install also crimson 17.4.3 to avoid bios check verification, but after amd driver install I have windows crash and I have to reinstall all from begin.

    • You will have to use combined drivers, or to apply the patch for bios signature.. about the samsung memory yes.. i have a bios now, just made some tests today..

      • Manuel Casara

        .g

      • Eramo88

        Has there been any update with the samsung memory for the bios?

      • James B. Fitzgerald

        Hi Ciprian, Could you share your results with the Samsung memory. I recently modified my own RX 580 Limited Edition by following this tutorial.

        I was able to get 30 MH/s but the card is underperforming compared to my Special Editions.

        SE: 1150/2200, 30.6 MH/s, 100W
        LE: 1200/2200, 30.2 MH/s, 110W

        I’m using the AMD Blockchain driver and setting the clocks with Wattman.

        I’m wondering if more can be done within the BIOS to get the more hashes for less power.

  • geoff

    thanks again for the guides….

    I’m having really trouble with my setup with the bios and wanted to ask a question? however this isn’t in the right section? can I speak direct or best to do it through this messaging

    • hi, yes go ahead

      • geoff

        I’m new to mining and struggling with this over clocking / undervolting..etc… I’m downloading so many bios..etc.. then using certainly examples of claymore config to get the extra juice out of these cards.

        However what I have noticed I get completely different results if I’m using linux or windows with the same command line. Can claymore under volt in linux?

        I cannot get up to 30mhz its always this – I mean 167mhz is better than nothing however I know it can do more…

        ETH – Total Speed: 167.393 Mh/s, Total Shares: 63, Rejected: 0, Time: 00:26
        ETH: GPU0 27.937 Mh/s, GPU1 27.862 Mh/s, GPU2 27.862 Mh/s, GPU3 27.868 Mh/s, GPU4 27.929 Mh/s, GPU5 27.935 Mh/s

        This is in linux and the same in windows using this bios – http://1stminingrig.com/best-bios-rom-sapphire-nitro-rx-580-8gb-oc-hynix-memory-30-mhs/ for the Sapphire, and for the XFX I’ve just changed the strapping 1750 and 2000..etc.. I have tried copying the Sapphire config within the bios editor to the xfx via the bios editor and the results were the same.

        The graphic cards are:

        Sapphire AMD Radeon RX 580 8GB NITRO+ Graphics Card x 3
        XFX RX-580P8DBRR GTR Radeon RX 580 8GB Black Edition 1405 Mhz OC Core clock x 3

        I’m not asking for the exact figures to put but some guides on what all these figures mean, so then I can test various setups and get to the best for me. this is what I’m putting in claymore

        -tstop 85 -tt 65 -fanmin 60 -fanmax 100 -cclock 1130 -mclock 2150 -cvddc 850 -mvddc 850

        sorry to ask such a basic question, however just think I’m missing something… 🙂

        Thanks in advance, hopefully you can point me in the right direction.

        • Hello, first of all you will have to test every card alone on the rig and write down the settings for each of them. then once you connect all gpus, find the order and apply the clocks you tested earlier.. for me that is the best start to stabilize the rig when having mixed GPUS.

          • geoff

            Thank you for the reply – I know you have dozens of replies to do. This is great news however can you do a guide to say what numbers really I should be changing. I.e. I’ve written the numbers of standard bios and then looked at yours bios and for example yours is set to 30mhz what numbers would I need to lower or higher it to 29 or indeed 32?

            whar settings should I be changing ? And which ones to leave alone?

  • Tim Bos

    This is great, thanks. I’ve applied the settings for the ETH + SIA dual mine, but I’m only getting 27.7MH/s ETH and 526MH/s SIA. I’ve flashed the bios, and set the claymore settings as above, but it doesn’t seem to be close to the numbers you have above.

    Any thoughts? I’m running Claymore 9.5 on Ubuntu.

    • what is your dcri and cloks ?

      • Tim Bos

        DCRI I’ve tried everything from 15 to 30. I settled on 23. I tried 19 as suggested, but that put my hash at 26MH/s for ETH.
        MClock = 2250 (tried 2150 also)
        Clock = 1200

        • Tim Bos

          I’ll try baking the clock speeds into the rom and see if that helps. Doubtful, but worth a try.

        • I tried the same settings on 9 different cards and all of the performed the same.. hmm.. maybe you are missing something ?

      • Tim Bos

        Hi @ciprianpt – if I want to bake the clocks into the ROM, are these the correct settings to change (attached image)? The GPU freq at 1200 seems awfully low??

        https://uploads.disquscdn.com/images/4db300f85101cf1a8e70027dfcb0db870f055805924233256206b04741412ab0.png

  • jorge viloria

    This bios apply for rx 580 sapphire pulse must be similar right ?

    • Tim Bos

      No. The memory and CPU timings are different.

  • Nexes

    Does it also work for the ‘SAPPHIRE NITRO+ RX 580 8GB’ version?

    • nope, there is another post for that gpu

  • Anastasios Selalmazidis

    Hello there,

    Is the Limited edition GPU a new one or an old one ? Will it be available soon ?

  • Takuya Noda

    HELLO
    I regreted deeply saw your article so I bought HIS RX580 HYNIX…..
    then compare yours with mine by polaris-editor,the same value written without 2:1750-2250.so I’m thinking of copying.Do you think my plan gets results?

  • sora adonis

    Hi, do you have tutorial for stock settings only for the RX580 4GB version? I’m not tech savy and I don’t want to brick my 3 GPU cards. Thanks in advance.

  • Cristian

    Hello, will this also work on RX480 Nitro cards (hynix)?

  • Marcelo Moraes

    This post just saved my life thanks =)

  • Bartosz Nowacki
  • Manuel Casara

    I would like to ask a question.
    But rams in overclock and with lower timing, how long does it break everything?

    I think rams can not last more than two years under these conditions.

    It is very important to cool everything well, but are we sure that after a year at most it will not break everything?…

  • João Rocha

    Thanks for this great tutorial.

    Wondering if you’ve any specs for the BIOS for Sapphire RX 570 NITRO+ (Hynix).

    • Nope, but we can work on it if you want..

      • João Rocha

        @ciprianpt:disqus If possible, please, do. 🙂

        • We will have to do this via teamviewer to test it 🙂 send me your skype via contact page, thanks!

          • João Rocha

            Found you on skype (and added).

          • João Rocha

            Managed to set 29.1Mhz into the RX 570 4G. Thanks anyway 🙂

  • Анисов Александр

    I sell 9 pieces of Antminer S9, one costs $ 1300, if you buy immediately 9, then I’ll give you cheaper for $ 9900!

  • 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!…

    512Kb version:

    https://mega.nz/#!RqxiRLhb!…

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

    Next, some statistics.

    You can see everything on screenshots:

    • João Rocha

      any chance for those parameters work into Sapphire Nitro+ 570 4g?

      • Ti

        Not sure. Hynix memory?

        • João Rocha

          Indeed. It’s Hynix.

          • Ti

            Then is should work. Try. But don’t forget about safety:
            -backup BIOS;
            -switch to silent BIOS;
            -modify your BIOS rom, and use it to flash your card instead of using my roms.
            Good luck!

          • João Rocha

            Thanks.

            My GPU, with factory setup, has the following.
            Front Switch (Silent): 1244 Memory: 1750
            Back Switch (OC): 1350 Memory: 1750

          • João Rocha

            What’s the difference between 256 and 512 KB versions?

            Also, while trying to download your files… it asks for a password.

          • Ti

            Depending on card revision there is flash memory modules (where BIOS is stored) with different capacity – 256Kb or 512Kb.

            So I uploaded roms for different flash modules. But BIOS parameters is same in both roms.

          • João Rocha

            The backup save has 256KB therefore that should be it. Concerning the file you upload to MEGA, can I test it out? (cant download it… It’s asking for a Decryption Key).

    • João Rocha

      Can you please fix the MEGA files? I’m unable to download them 🙁

      • Ti

        Replaced links in my comment. Try it.

        • João Rocha

          BIOS downloads are fine. Your configs still with problem. 🙂

          • Ti

            Try it now 🙂

          • João Rocha

            Thanks.

            FYI, and all the rest, that FW doesnt work properly with Sapphire RX570 4G Hynix (24.8 Mh/s ETH; Crimson 17.5.2)

          • Ti

            Quite expected 🙂

    • minna torre

      Nice Post Ti!
      do you think that your mods ar useful for the RX580 8GB Pulse Version Hynix memory?
      Now I reach 29.4 Maximum.
      Thank you
      Vito

    • Mario Morante

      nice post. I did exactly what u did. But I am only able to get 28,4 H/S. Anyone know what might be the problem?

    • Hello Ti, is that for standart RX 580 Nitro+ 8gb Oc or is it also for Limited Edition?
      Thanks! 🙂

      • Do I also need the combined drivers or the latest one would work?

        • Ti

          I didn’t noticed any difference.

          • So you mean you combined the drivers as in the main guide, or just changed the settings you mentioned? Can i reach you on facebook or whataspp? 🙂

          • Ti

      • Ti

        Hi.
        It’s for both.

        • Thanks!

        • nVn

          And for the SPECIAL EDITION gonna work as well?

  • THPQT

    I have a question as I have Hynix Memory so in theory this would work on my Gigabyte RX 580 8gb?

    If so, I would follow these steps but step 3 wouldn’t work as I have a diff GPU?

    • João Rocha

      You mean the switch step? In the sapphire case that’s a switch and not a button (turn it to back side to set OC mode)

  • Ti

    Hi again, guys!
    Maybe some of you had already noticed that hashrate is slowly decreases as epoch increases.

    You can read info about it here:
    http://www.legitreviews.com/ethereum-hashrate-performance-drop-might-coming-amd-nvidia-gpus-tested_195702

    Share your experience. Maybe some of you already found solution (before AMD)?

    Regards.

  • Fabien

    Hi, I have a Sapphire Nitro + Special edition RX 580 8Gb with Hynix memory, ¿Do you know if I can mod the bios similar at Limited Edition? Thx for your help

    • nVn

      Same question here!!

      • y. emre

        did you try the mod ?

        • nVn

          Yes i did. And it works!! 31mhz and stable. So far so good.

          • y. emre

            Thank you for the reply dude! I was very nervous because i spent 3k on those cards they will arrive next week. Just to be clear, you you did the v1 rom not the v2 which is given in the comment section? And do you have any additional advice for the operation. Thank you so much you made me happy 😀

          • nVn

            I used the V1. I downloaded from the link on the step 5 of this guide. Remeber pass the switch to the silent bios, and make your backup. The good thing is that you have an extra bios in case you mess up. I was nervous too, im not an expert, but if you follow this guide everting will be ok. Good luck.

    • y. emre

      did you solve the problem ?

  • Charles McPhail

    For NiceHash, they have extra launch parameters for each of the miners. i tried using this bios and also putting in “-dual=decred -tstop 85 -tt 65 -fanmin 60 -fanmax 100 -cclock 1200 -mclock 2250 -cvddc 850 -mvddc 850 -dcri 30” and it works… but not as good as your numbers. 27/28 Mh/s for Eth , decred about 800. any ideas? should i give up using nicehash? It’s just easier to use for a beginner.

  • Ti

    Hi again guys!
    I was working around to figure out how to make this new beta driver (one with “DAG issue” fix) work stable, run without memory controller errors, use less power and keep temp on ~50 degrees. And finally I’ve found sweet spot 🙂

    THIS IS ONLY FOR BETA DRIVER!
    THIS IS ONLY FOR HYNIX MEMORY!

    256 kb ROM:
    https://mega.nz/#!43xRHaaa!4FfO3Z2adC6oj7TxHyiaM5AKlNnLUX9x8szAv3RVNw8

    512 kb ROM:
    https://mega.nz/#!5uwFBASK!a2NE9i-OqrQwODvEuRziVrWJsH3k5Lec5K5z9cm0kzo

    Only difference from my previous rom is lower clocks – 1100/2100 (prev. 1150/2150). Yeah, this is the only way… (that I’ve found after 48 hours testing…).

    PLEASE NOTICE! DO NOT MODIFY CLOCKS IN MSI AB OR VIA MINER!

    Target clocks and voltage need to be flashed in bios. This is because when you set clocks to any other values than stored in bios using MSI Afterburner (4.4.0 beta 15 works fine with beta driver) or via miner, driver will reset voltage settings to defaults. So you’ll get power consumption on GPU = 135-140W (from wall = even higher), and temp about 65 degrees. Beta driver, so…

    Results with 6 GPU rig (ETH-Only mode):
    178 mH/s
    ~90w on GPU
    0 memory controller errors
    ~2.5 shares/minute (ethermine.org)

    To say the true, although hashrate is 178, final outcome is the same to prev., when I was using official driver and set 1200/2200 clocks for core and mem, and had 175 mH/s on 137 epoch. It was about 2.5 shares per minute….

    If any of you guys figure out how to get better results, please, share with others.

    Peace!

      Thanks for bios update. I am gettin 26.88 Mh/s. 93w and ~50-55 temp

      Is there any way to improve hash rate ??

      I am using amd 17.7.2 driver and claymore 9.7

      • Ti

        Hi!
        Try AMD beta driver.

        • Mit

          will try, can you share both download links ?

          • guys… stop using the unoficial release of a driver. it can be backdored.. wait for the official release..

          • Ti

            Whaaat? Unofficial?? Backdoored??? O_o
            Dude, it’s AMD’s closed beta driver for Windows 10 (64-bit)…

        • guys… stop using the unoficial release of a driver. it can be backdored.. wait for the official release

    • Mit

      working stable, thanks TI

      i am getting 29.xxx on all my 14x RX580 power consumtion is 100~110w and temp 50~60

    • ZeroCool

      Thx for bios,

      getting 32 & 980dcr @ 31dcri @116watts

    • francis qureshi

      Worked great! I have upped my clocks a tad in wattman and squeezed a little more from my Rx 580 Nitro 8gb’s — Geting 30mH/s / 930cdr @ 109 watts on GPu-Z

      Thanks @disqus_8LuuwzNkwH:disqus !

    • eltimmo

      Thanks @Ti so glad I found your ROM, my system was so unstable. Running sweet now 🙂

        Nice 😉

  • Hi,

    I just got 2 new RX580

    I’m a bit confused about the switch setting on the RX580 for the silent bios.
    Above is noted that “For this card the bios is already switched to NON OC version (HDMI SIDE)”
    But when I unpack my new RX580, it seems the other way around?
    http://imgur.com/3lYLhcQ
    2 RX580 in the picture below,
    on the picture, the lower one (1) is unchange out of the box. Assuming you mean with “HDMI SIDE” the rightside (where the all connections are), it is the other way around, no?
    So just to be sure, which bios is which? Or which bios is the one to mod?
    1= ?
    2= ?
    Thanks

    • Switch to HDMI side, backup the bios, do the modifications and flash it again..

  • Hi,

    a question I’ve thrown out mu Asus H270 MB (as it refused to recognize more than 1 GPU via a riser cable) (it is just new, so I’ll sell it again)

    so I’m now equipped with an ASROCK H110 Pro BTC+, but I’m still struggling:
    – followed the instructions for the latest official beta driver with DAG fix, including the atikmdag patch
    – using onboard GPU for display, with basic driver
    – speed of the PCIe slots all set to Gen2
    – using 1x 850W PSU (I assume it would be able to power at least 3 GPU’s, no?)
    – I’ve 2 RX580, connected via powered risers, 1x 8-pin power per card connected (as Ciprian mentioned elsewhere)
    – they show up fine in W10 device manager
    BUT
    – when I want to connect one of my older R9 390 cards, or the rig does not boot past the BIOS screen (and freezes), or it boots through, but none of the extra cards show up in the device manager
    – I’ve already tried 2 different R9 390 cards and a R9 380
    – also tried different riser cables
    so I’m a bit lost at the moment.
    anyone ideas?

    Thanks

    • Hi,
      I still have no luck in having more than 2 GPU’s recognized by the ASROCK MB. the 2 first RX580 are recognized fine, whatever I add (3rd rx580, R9 390…), it does not work.
      The only thing which happens when adding a 3rd card is one of the below:
      – it freezes on the bootscreen
      – it boots into windows but NONE of the GPU’s are found (monitor is on the onboard DVI)
      – it boots into windows, and only the first 2 RX580 are found
      I’ve been breaking my head on it for the last 4 days 🙁
      any help is appreciated
      thanks

      • found the issue… apparently I had very very very bad luck with the powered risers… the 3rd set seems to be working

  • nVn

    Does anyone know if this BIOS works on a rx580 nitro 8gb Hynix ESPECIAL EDITION?

    • denisjoshua

      Same bios 🙂
      I have the special edition and work well

  • louis larouche

    Hi Ciprian, Will this bios mod work on my Sapphire Nitro+ Rx 570 8GB Hynix? If not do you know a good bios mod + launch settings for those rx 570 please? I saw some people getting close to those 30-31mhs with rx 570 8gb like mine too.

    • Hi, i didn’t had this gpu yet.. can you send me the bios ?

      • louis larouche

        Yeah sure how can I send you the bios file? 🙂

  • denisjoshua

    I get a stable 31.5-8 but the consum is little hight… about 140-150 Watt
    Can anybody post the best settings in order to make 31 mh and low consum please ?
    Thanks

  • Thai Dinh

    power 150w…Do not power down 100w. help me

  • Javier Sánchez-Bonilla Martíne

    Can I get the same performance with Sapphire Pulse 580 8GB doing what you have done?

  • Thanks to all tutorials by Ciprian V. currently testing a stable miningsetup:
    – Win10
    – 3x RX580 Sapphire Nitro+ 8GB (with a 256K Bios apparently)
    – to test : each card flashed with a different rom from the other thread (http://1stminingrig.com/best-bios-rom-sapphire-nitro-rx-580-8gb-limited-edition-hynix-memory-31-5-mhs/), using : one card with the Jared rom, once card with the Ashley rom, one card with the erlendfr rom.
    – Official AMD Beta drivers (Package Version 17.30.1029-170808a2-316962E-CrimsonReLive)
    – Only using Watmman
    – All 3 cards set to
    – – Clocks: 1130 / 2200
    – – Core voltage: 850
    – – Memory Voltage: 850
    Current results, stable for the last 5 days :
    ETH – Total Speed: 90.591 Mh/s,
    ETH: GPU0 30.163 Mh/s, GPU1 30.172 Mh/s, GPU2 30.256 Mh/s
    DCR – Total Speed: 2717.723 Mh/s,
    DCR: GPU0 904.886 Mh/s, GPU1 905.160 Mh/s, GPU2 907.677 Mh/s
    GPU0 t=75C fan=29%, GPU1 t=75C fan=32%, GPU2 t=66C fan=23%

    So the 3 roms seem equal in performance (in my case)

    the only downside of wattman, there is no option to save settings in a profile, for easy restore when wattman resets itself (due to system issues and so on)
    but I think I found a way to restore my settings:
    – found the regkeys where the settings are stored,
    – set all your settings for all your cards
    – export those hives to a regfile (from what I saw in changes, there is one hive per card)
    – of for some reason wattman has resetted everyting
    – import those regfiles, and reboot the system (it needs a reboot to reload from the registry)
    – after the reboot, it has my settings back

      Hey LiteBit,
      I have the same cards but I can only get 29Mh/s and a high consumption (120w). Could you please share the Bios you are using? You said you only use Watmman, meaning that you are not using MSI Afterburner or Trixx to overclock your cards?
      Thanks a lot!

      • Hmm for some reason, I don’t find the roms in that threat anymore, or I’ve the wrong thread. Anyway, I uploaded all the BIOSmods I have here : https://mega.nz/#!JQZwgLDZ

        as said : one card with the Jared rom, once card with the Ashley rom, one card with the erlendfr rom

        (you’ll see it in the filenames)
        and yes, follolowing @ciprianpt:disqus instructions, only Wattman seems to work. so I’m not using Trixx or Afterbuner anymore

        • unichiduci

          thanks a lot LiteBit!
          Still, I need a decryption key in order to download the files from the link you provided.. 🙂

  • dave

    Hi Ti, thanks for the firmware , so you mean no need to use after burner anymore with your flash? and does it woks fine on the hynix 8gb nitro + rx580 , my card not limited , but i think it’s the same no? so if we flash it with your flash no need for AB ?
    Thanks

  • Kang Zai

    Guys do you have modded bios for Sapphire Nitro+ RX 570 8 GB hynix memory ? if has can share?
