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..

Software and Tools used for this tutorial

Let get started!

3 Switch BIOS to silent mode (display ports side)

4 Backup “Silent” BIOS

Before to continue further, please share this ๐Ÿ™‚ 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

  • 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 ๐Ÿ™‚

      • Rostislav Rusev


        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.


        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 ๐Ÿ™ 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 ๐Ÿ™‚

  • 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 ๐Ÿ™ 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 Chiลฃimiea

    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


    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.

  • ะ˜ะปัŒั ะจะธัˆะบะธะฝ

    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 ๐Ÿ™‚

        • 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 Friend,
            Can you help me, how do I configure sapphire rx580 8gb special edition, I started mining with Claymore CryptoNote GPU Miner in Slushpool & Even in Minergate. Was only showing 800 H/s in Minergate & Slushpool 281 H/s.
            As per my search in online forums, I founds rx 580 output is around 30 MH/s.
            Can you help me.

    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 ๐Ÿ™‚

      • 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 ๐Ÿ™‚

  • 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 ?

  • 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 ๐Ÿ™‚

  • 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.


  • 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?
