Best BIOS ROM for Sapphire Nitro+ RX 580 8GB Special Edition Hynix Memory 31+ MH/s

Ledger Wallet protects your bitcoins

Here is another BIOS long waited for most of you, but thanks to Igor i was able to test the Sapphire RX 580 8GB Special Edition remotely via teamviewer. I must say that the Special Edition GPU is awesome, just like the Limited Edition and Nitro+ with great hashrate, stability and undervolt control.

I didn’t had an energy meter to check power consumption from wall, but based on GPU-z reports i can come up with something very close to reality.

The benchmarks were done for the following:

Ethash Algorithm

  • Ethereum (ETH)
  • Ethereum Classic (ETC)
  • Ubiq (UBQ)
  • Expanse (EXP)
  • Soilcoin (SOIL)
  • Musicoin (MUSIC)
  • etc..

Equihash Algorithm

  • ZCash (ZEC)
  • Zclassic (ZCL)
  • Komodo (KMD)
  • Hush (HUSH)
  • Zencash (ZEN)
  • etc..

CryptoNight Algorithm

  • Monero (XMR)
  • ByteCoin (BCN)
  • Sumokoin (SUMO)
  • Karbowanec (KRB)
  • DigitalNote (XDN)
  • etc..

  • Sarunas C

    Hi Ciprian, perhaps you would be interested test the same card with Samsung memory? I have troubles finding stable combination of clocks/underwolt and bios for my 6 card rig.

    • yes sure 🙂

      • Rostislav Rusev

        Hello,

        Using latest blockchain driver from AMD and Claymore 10. Rx 580+ Special edition 6xHynix and 6xSamsung. I used the patch, make 32gb virtual memory but stil on dual mining my ETH Hash fall down from 32mh/s to 27.5 ? Do you know where could be the problem.

        Hynix:

        Not more than 27.7 Mh/s ETH and 506Mh/s Scia … by your observation where is the problem. I used your setings from this post. 850/850/1200/2250 dcri varies from 17 to 21. With this setup 1050W on the wall.

        Still to be tested on Samsung.

        • hmm i did not tested with samsung memory 🙁 we can do that via teamviewer..

          • Rostislav Rusev

            Dear, i follow your guide and with the info from above i did not receive the MH/s as you wrote but far worse than yours. Could you help with choosing the correct driver and claymore agent . Which one did you use to dual mine ETH and SC with 31.5 and 570mh/s? I am waiting for your responce. In what way you make the setup of the bios and the drivers which you use for that perfect dualmining speeds.

          • Henk
          • Nope….

    • GratefulActor

      I just returned a Special Edition 8GB Samsung. The best results I could achieve was 30.5 Mh/s 1200/2090 900 cvddc with Samsung 1750 strap mod. Memory overclock at 2100 and above crashes. In addition, the card would consume 30 watts more than my other Special Edition 8GB Hynix. Hope that helps!

  • GratefulActor

    Hey Ciprian!

    I want to thank you for offering such a valuable resource. Based on your guidance, I built a 13-GPU rig with 2 Special Edition (one Hynix/ one Samsung) and 11 Nitro+ (Hynix). I just returned the Special Edition with Samsung, and ordered another Nitro+. Based on the serial number (1459 or something), I believe that Hynix memory are the newer batch for Special Editions; 5 digit serial. But seriously, THANK YOU alot!

    BTW… what is the difference between the Special Edition bios and the Limited Edition bios you’re using? I currently have 12 GPU’s (1 Special Edition Hynix and 11 Nitro+ Hynix) with the Limited Edition bios hashing like champs at 31.5 Mh/s on SmOS at 1200/2250 850 cvddc drawing 2070 watts from the wall. When I switch to 1150/2250, they hash at 30.7 Mh/s drawing 2040 watts from the wall; 12 x 0.8 Mh/s sacrifice for 30 watts savings. I’m wondering if perhaps the power stages are improved on your new Special Edition bios.

    Cheers! =)

    • Hey @gratefulactor:disqus , i find both special edition and limited editions same cards MAYBE special one have more OC and also can handle it better, can’t tell too much because i didn’t had the card in my had to compare it. But the bios looks the same to me 🙂

    • Jerry

      Hey GratefulActor,

      just wondering why is your power draw so high? I have 12 GPUs MSI RX580s each outputting 30+ MHs and the total draw from wall is 1680W. I am using EthOS.

      Just got bunch of Sapphire RX580 8GB SE. In windows I can get 31.5MHs with 80W GPU Only and about 120W from wall. In Linux 30.2. You have mentioned that SmOS gives you 31.5MHs how did you manage to get it? Is it SmOS thing? As far as I know Linux works only with power tune modes and it does not honor claymore’s voltage settings.

      I would really love to stay with Linux but if Windows spits out more hashes unfortunately I have to switch to it.

      Thank you.

      • MalsBrownCoat

        Jerry, for your Sapphires (not your MSIs), are you setting your voltages/clock speeds through the batch file? And if so, can you share your config? Or are you using Afterburner/another tweaking app?
        I’ve tried using the settings in the article, and I think I’m pretty adept with following directions, but I can’t get anywhere near 80 watts/gpu (on Windows).

    • Have you also tried to apply mvvdc ? Power draw is high :/

  • Foued Alias

    Hi Ciprian Please can you modded for us a bios for the RX 580 Pulse 8GB ? because i have try and a got only 25 MH/S 🙁 175MH/S with 1400W for 7 RX 580 8GB …

  • Panc2001br

    I guess that isn’t the new Claymore’s cryptonote 10.2. This new version worth a try

  • Cosmin Chiţimiea

    Salut Ciprian,cum pot da si eu de tine?

  • Panc2001br

    The blue fan’s leds all turned into green in just few days. Anyone with the same “problem”?

    • Isn’t that the led and the color can be changed from driver ?

      • Panc2001br

        No. Fan’s led can’t be changed, only logo’s one

    • Konstantin

      Yes, I had the same problem but after a while some of them started to change back to blue.

    • One2

      Yes, it’s the dust. Clean them.

  • Bandi Su

    mine only got 26 Mh/s…before using this got 29.

  • Jason Ang

    Hi! Can you confirm if this works with SAPPHIRE nitro+ 8GB HYNIX? NON limited edition?

      • Jason Ang

        Yes. I am currently using them. Is this any different? I thought maybe it will perform better. Currently getting about 29+ with the Rom from post you pointed out

      • andika cahya

        dear cipirian, when you gonna do team viewer for me, its for my 470 mining edition elpida . which draw to much power even after undervolt with AB. thanks

        • yes will do it asap, can you re-send the email ?

          • andika cahya

            sent again SIR

  • JMCDor

    Hello.

    May anyone post what are the Special Edition serial numbers corresponding to Samsung and Hynix memory?

    Thanks in advance.

  • Rex Buensuceso

    Can i use these to my rx 570 nitro+ 4gb

  • Willy Iglesias

    mate can this be used on Sapphire RX 580 4GB Elpida memory cards? i cant ifnd any for it.

  • Илья Шишкин

    In step 3 we had switched bios. Do we flash new modified rom in silent bios or we have to switch back bios to normal ?

    • Yes, flash it in silent bios, make sure you have a backup of it.

  • Etele Bogdan

    Salut,, if setting in claymore, no need to use afterburner at all? Can i use the claymore settings for my 480 rig as well? Merci.

    • Yes, you can oc and undervolt the cards directly from .bat file without using any other software.

      • Etele Bogdan

        Thx, unfortunately it doesn’t work with my 480’s, just get blue screen when miner starts. Could you give us a setting that works with 480’s (nitro+ 8gb samsung rom)? I set up the 580se rig tomo hope it’s an easy job 🙂

        • GratefulActor

          When using those settings in Claymore on Windows, it may crash because the GPU is also supplying video output. Those Claymore setting work fine on Linux or Ubuntu.

    Hello Ciprian V,

    Can you tell me how to configure AMD SAPPHIRE NITRO+ RX 580 8GB LIMITED EDITION to get 30 MH/s

    I’m new to this rig mining.

  • globalb2bsolutions

    I’m planning to mine Zcash or Moreno with Rx 580. Do let me know how to configure.

  • globalb2bsolutions

    Hello Friends,

    Do help me how to configure Rx 580 Bios to get 30 MH/s for Zcash or XMR

    • Hi, you are taking this wrong. 30Mh/s is for Ethereum (Ethash), on Monero the usual hashrate is 800+ H/s and for ZCash 300 H/s. your card is running just fine 🙂

      • globalb2bsolutions

        So you mean,its not possible to get 30 MH/s for Zcash & XMR

        • nope.. different algos

          • globalb2bsolutions

            CLAYMORE GPU 9.7 ???

          • globalb2bsolutions

            Can you setup my miner with Rx 580

          • globalb2bsolutions

            How about Linux or Ubuntu ??

  • ZekDet

    Hello, perfect job Ciprian, thanks.
    I would like to ask, how many Sapphire RX580 Nitros will be recognised in win10 64bit? I use linux (with 12x cards) but I would like to try Win.

    • GratefulActor

      The limitation in Windows today is 8-GPU’s per driver. 2 drivers (AMD + Nvidia) = 16-GPU’s. Your scenario… 8-AMD GPU’s.

    • Up to 8 GPUs 🙂

  • Norman Hirsch

    I’d like to see the best bios for the MSI Gaming X RX580 8g card. BTW, Polaris Bios editor shows one group of memory is Samsung, the other group Hynix.

  • F Uzcategui

    there is any mod for sAPPHIRE NITRO+ RX 570 8GB HYNIX ?

    • soon..

      • zeindana

        i’ll waiting too, bro…

  • Dani Putra

    As always.. Nice tutorial. Can you share some tutorial for msi rx 570 gaming x 4gb to mine monero? Coz i only get around 740H/s (voz i think it’s abit to low). For eth only i got 30,1mh/s,dual eth+dcr i got 28.8mh/s+710mh/s.

    • Usually that’s the best hashrate for monero 🙂

  • Andrew

    I am only able to get approximately 28.3-28.5mh/s for ETH using Claymore for this card and the settings above. Any idea why or let me know what additional information you may need to help troubleshoot.

    Thanks,

    • What drivers are you using ?

      • Andrew

        I am using the blockchain drivers. When I go to the Radeon settings, it says “17.30.1029-170808a2-31730….” under the “currently installed” http://support.amd.com/en-us/kb-articles/Pages/Radeon-Software-Crimson-ReLive-Edition-Beta-for-Blockchain-Compute-Release-Notes.aspx

        • Andrew

          Any other thoughts??

          • Have you tried settings -dcri 4 ?

          • Andrew

            So I just restored the bios to the original and then re-flashed it with the one you have above and I am still getting the same of about 28.3 mh/s. I have also tried using -dcri 4. I am not sure what else it could be. Also running -cclock 1200 -mclock 2250 -cvddc 850 -mvddc 850.

            One other thing – I have the same “special edition” card except with Samsung memory. Do you have any tutorial or recommendations for this same card with Samsung memory?

            Thanks!

          • I lnly had the chance to test the one with hynix mem..

  • One2

    I have some SE cards but none are stable at 850 cvddc. The lowest was 950 cvddc using blockchain driver.
    A small number of cards are stable with memory at 2250, test before.
    Also i have a weird problem.
    When claymore starts at startup it mines with 28.x. If i restart it it goes to 31.
    Anyone with the same issue?

    • g_dogg

      I saw this problem with my cards. It seems like a overclocking had not applied

      • Donny

        Overclock has been applied to the cards, but it happens once in a while, especially after restart from electricity outage.

    • Donny

      Yes sometimes, not everytime though, it happens to my cards as well. I haven’t yet found solution for this. Anyone find solution for this?

  • g_dogg

    Help me pls! I have no ideas. My rig does not work with this ROM and more the 4 cards. If I put on 5th card my rig drop down every half hour. Failure in windows log says amdkmag driver had stopped and restored. Before I had flashed rom 5 cards was working with default bios and gave me 22MH.

    • what drivers and clocks ?

      • g_dogg

        Amd blockchain driver, clock I’ve tryed 2100, 2150, 2200

        • Virtual memory increased ?

          • g_dogg

            If you mean swap, yes. 25gb

          • swap?

          • g_dogg

            Yes, sometimes called swap. Virtual memory it is file on HDD using if not enougth RAM. Am I right? I made it 25 Gb

          • g_dogg

            @ciprianpt:disqus did you mean virtual memory is it what we increase in system properties ? When we right click on “My computer” shortcut.Right?

          • yes..

          • g_dogg

            As I said, I’ve increased it. 25Gb. Are there anything ideas? Yesterday I tryed to launch 5 cards and rig dropeed down after 1 hour ((((

          • i fixed this one by reinstalling everything.. :/

          • g_dogg

            Hm! Ok, I will try to resolve it in this way. Thank you!

  • Donny

    Hi Ciprian, I followed your instruction with flash bios V1 that you provided. I am using this driver non-whql-win10-64bit-radeon-software-crimson-relive-17.10.1-oct6. After flashing the bios, I could not get near 31.8 MH/s, only 25.5 MH/s.
    And not only that, the power consumption is 138W.
    Do I need to switch BIOS to non-silent mode after bios flashing?

    Is there something that I might doing wrong? maybe the wrong driver? Could you shed some lights? This is from GPUz http://prntscr.com/h11odm. Thanks.

    • Hi @disqus_ZmpjbOZe9Z:disqus , you should use the official mining drivers to get that hashrate, check here: http://1stminingrig.com/ethereum-dag-hashrate-drop-fix-amd-official-mining-drivers-are-now-out/#How_to_fix_Ethereum_Ethash_DAG_epoch_hashrate_drop

      • Donny

        Hi @Ciprian, the wattage becomes 78W but I still get 25 MH/s.
        Do you install that driver including the software? or just the driver via Device Manager?

        • Have you increased the clocks ?

          • Donny

            I am using claymore script that you provided above. Do I need to increase the clocks elsewhere?

          • Donny

            I finally got it, but not all of them 31 MH/s, the other are 28 MH/s is this common? How do I increase this 28 MH/s to 31 MH/s ?

          • try -dcri 4

          • Donny

            @Ciprian V. I read -dcri option in claymore readme but don’t fully understand it. What is the difference between 8/12 and 4? How does this setting effect for mining? Thanks.

          • Default -dcri is 30, by lowering it will increase intensity for ethereum hashrate. Usually this is applied when dual mining for example if you mine ethereum dual decred the ethereum hashrate will be around 28.xx mh/s with dcri 30, but decreasing it to 23 the hashrate for ethereum will increase like 29.xx – 30.xx mh/s (usually dcri 23 is the best when dual decred). If you go up to 35 or 45 etc.. with dcri then the intensity will be higher for decred which means lower hashrate for ethereum and bigger for decred:)

            Claymore enabled dcri for ethereum mining only too, because of this 🙂 try finding the best dcri by switching it with + and – , for me the best spot is 4-5.

          • Donny

            Hi @ciprianpt:disqus does this setting works on more than 6 gpu?
            Also, sometimes one of the gpu hangs and then the miner needs to restart. Do you think this is due to the low watt?

          • try to increase voltage or lower mem clock

  • Karlos

    Hi guys! I have a question about flashing bios back to original. I have 3 rx 580 with Hynix memory like in this tutorial, which I flashed. BUT I was so stupid that I overlooked 2 things: 1st – I didn’t switched to silent mode, so I flashed OC bios. 2nd – I wanted to flash bios back to original, but I didn’t see when I was doing backup, that file with backup had 0Kb… It didn’t show any error, so I thought everything is fine. Now from 3 cards, I have only one original bios from second card. Can use this bios also for other cards? One more question – why it is needed to flash silent mode bios? Thank you guys for answers and suggestions.

    • You can use the original bios from non flashed cards 🙂 , flashing on silent mode or oc mode doesn’t really matter, i am doing it there because the silent bios version is modified.

      • Karlos

        Thank you. So I’ll not flash it if there is no reason in silent mode. Anyway thank you so much for your tutorial! Now I’m mining 3x 31+ MH/s with rx580 Hynix and 3x 30+ MH/s with rx580 Samsung memory so 186 MH/s in total with 1.1 KW in dual mining mode which I think is not bad.

  • Umer

    Anyone know how to disable ‘Fan Stop’ feature on this card?

    Hello Ciprian, did you tried new AMD beta Fall Creator drivers (Non-WHQL-Win10-64Bit-Radeon-Software-Crimson-Beta-Fall-Update-Oct16) with Sapphire Nitro+ Special Edition, or with any other GPU’s? There was added an option to swich GPU Workload between Graphics and Compute. I have Sapphire Nitro+ 8GB SE with Samsung memory, got ETH 30.9 Mh/s – DCR 927 Mh/s with same settings like in your guide with Fall Creator drivers, but still didn’t try with beta blockchain

    Hello guys, i have successfully updated bios in this type of memory (Hynix) but in non special edition. Everything OK when i set in msi afterburnetr your values ( 1150/2250 ) i got 31Mh/s but also high power consumption from wall almost 200W. I have got rig with 4 rx 570 and i put there this card. Using original miner drivers, beta msi afterburner. MSI radeon rx 570 gaming 4g have 28,xxx Mh/s and i have 130w consumption per card

    • What miner do you use ?

      • Jakub

        Claymore 9.x and i also tested latest version of claymore 10.5

        • try overclocking from .bat file directly without using the msi afterburner. add this line -cclock 1200 -mclock 2250 -cvddc 875 -mvddc 875 -gser 2

          • Jakub

            thank you, i will try, i ve got in rig 2 types of card (4×570 1×580), i read that claymore can set each card specific values, do you have experiences with this?

          • Jakub

            Thank you man, everything works just fine. I get stable hash rate 31.5 Mhs with 150W . Undervolt trough claymore is much better than msi afterburner.

            Hello Jankb, can you confirm once more that you have flashed this ROM from RX 580 Nitro+ 8GB Special Edition to RX 580 8GB Nitro+ (not special and not limited edition)? Can you check SKU# of your card and see if it is: 11265-01-20G . Also a question for Ciprian – is this BIOS for SE be safe for ordinary Nitro+? THANKS!

          • Jakub

            Hi Goran, i cannot found via GPU z or HW info this SKU number, but when i check my orders in eshop, i found SKU in order description, i think SKU number is also on box, but i dont have box here. You can see it on picture below. When i was reading a tutorial, i compare table from HW info for GPU Specal edition with my “Normal” edition and details were absolutelly identical. I assumed that when it have same chip, it will be ok to flash that bios. Now i mining without complication, 875 mV, 31.5 MH/s almost zero errors. Isnt Specal edition special because of blue packing and this non important visual things? https://uploads.disquscdn.com/images/a4c39739fbedb700b8d83fd762392de424303adf99e4d9e3247863e43b9d5d87.png

            Yes Jakub, that’s SKU# from box label of my cards. I have also one Sapphire RX 580 8GB Nitro+ Special Edition (Hynix) and the card is working perfectly with the BIOS Ciprian provided here, I’ve been tested for days on dual mining ETH+DCR and everything worked well – it draws about 100W in GPU-Z, but other Nitro+ cards (that are not SE, just ordinary) have much higher power consumption – about 120-130W in ETH+DCR dual mining and about 90-100W in ETH only with modded bios that I have managed to find – they gives about 31,1-31,2 ETH in single mining but I have to go with 950mV for power in claymore… What power consumption you have in single and what in dual mining with this BIOS in this ordinary Nitro+ cards?

  • J Sun

    Hi, does this work with EthOS?

  • Николай Зудилин

    Hi Ciprian! All did as you have specified, the hash rate is very good, all happy, Thank you!!!! BUT there is one problem, too many mistakes from memory. The Program HWiNFO64. Tell me what to do in this case? Is there any solution? Thanks in advance!

    • No worries, keep on mining 😛

      • Николай Зудилин

        I understand correctly that this does not affect anything?

        • Jakub

          fully stable rig, 2 days working without restarts, sometimes i restart it manualy for reset counters, but on 580 i have 0, can be this errors caused by riser for example? https://uploads.disquscdn.com/images/33968c3a3c82f954fbc51d6339354d4a912fea67a01a30f531944fbf3e3f8621.png

          • Николай Зудилин

            Do you have 580 bugs under this BIOS?

          • Jakub

            Is that value also somewhere in sensor status or what do you exactly mean?

          • Николай Зудилин

            I mean, you have 580, 0 errors on the cards, which mod did you use?
            You have SAPPHIRE cards NITRO + GH 580 8GB SPECIAL edition of HYNIX MEMORY ?

          • Jakub

            i have one rx 580 without SE, but i am sorry, i forgot mentioned that i have diffrent settings, now i owerclock trough msi afterburner for -96 and clocking 2040 memory / 1070 core , with ciprian bios 28.321 Mh/s . 0 errors ( trough msi because claymore do stupid things with fans i cannot setup constant speed)

      • Jakub

        Ciprian, in claymore miner, when i set fan values with minus – -tt -50 it should have constant speed 50%. But fans are in automatic mode sometimes enabled and for moment disabled, what am i doing wrong?

        • temp is reached and the fans stop till temps goes high again.. i recommend -tt 60 -fanmin 65 -fanmax 100

  • Riadh Taihi

    Dear Karlos

    Could you please share the 580 SE samsung rom please?

    Email: ridamine@gmail.com
    riadtaihi@hotmail.com

  • Boki

    Hi Ciprian, I have the same cards but what is confusing me is that my rom is 512k when I save it to rom file with Atiflash and all your rom versions are 256k. Is there any way that I can make this work somehow? I am really desparate, thanks.

    • can you send me your rom please?

      • Boki

        I was not aware that my cards have both Hynix and Samsung memory which is why no Hynix modded bios worked for me. In GPU-Z it was written Hynix but I downloaded the latest Polaris bios editor and there I found out I have both types. I made simple solution by applying one click patch in Polaris which changed memory straps for each memory type and I am quite happy now with over 31 mh/s on eth only mining. By changing bios I got around 28 mh/s and then with adjusting settings in afterburner I managed around 31. Still have to test it in dual mining. Question, if I put GPU setting straight into bat file does it matter where I put them (before or after the mining sequence)?

  • FrankRizz07

    I’m really struggling here.. My problem is that I use Ubuntu for 12 x AMD Sapphire RX580 SE cards but only get around 23 Mh each. I did the bios flash above which leaves me 2 separate problems;
    1.) I don’t feel like the bio https://uploads.disquscdn.com/images/12f923f1384a9ad6ec3e056f26239370ef16e74e12a2af0577a61aa3dd9d512c.jpg s mod did anything (shouldn’t i be at least closer to 27/28 Mh?) – is it possible that it didn’t “take” even though it said successful?

    2.) I still need to undervolt the GPU’s bc it doesn’t work to do via Claymore miner in Linux. Can someone point me to the correct settings in a bios editor to do manually?

    Any help would be greatly appreciated! -Rizzo

    • What clocks and undervolt have you used?

      • FrankRizz07

        I flashed the bios that was attached to this post. After programming, it said successful and I rebooted. Simply did not see any change in performance.
        Using Ubuntu, so am NOT able to undervolt. This is why I pointed out #2 above.
        Thanks, -rizzo

  • HEki

    Hello,

    today i setup 6 of this cards on windows 10, asrock h110 pro btc+ mb and i got 31,9 MHs. I was so happy, but after a few minutes i get an error saying “wattman has encouted an error and was reseted back to its default values”. Claymore reseted and froze after reset … i used the same line as you specified here in claymore.

    Than i ran a normal bat file and i was getting around 28.6 MHs. But the driver crashed again as soon as i touched afterburner …

    • Try finding the card that cause this and increase the undervolt..

  • HEki

    OK! NEWS!

    Got 8 cards working! I dont know what was the problem yesterday, but everything went as it should today. I attached 1 card at a time and now i have 8 cards with 31.9 MHs and 1200w from wall.

    https://uploads.disquscdn.com/images/c4914b500dcd96155e3278e58fac2a68d7a738e5b4be3f6de6665aab6090be11.jpg

    i did have to change 850 to 875, othervise it was crashing.

    p.s. how do i turn of led light?? With trixx i managed to turn off only the sign on top of the cards, but not the actual led on the fans. Anyone knows?

    Hi Cyprian, does the SE version worth the extra 10% in price vs. nitro+ rx 580 8Gb? Looking at the numbers it does not have 10% more hash rates..
