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


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..

Let get started!

3 Switch BIOS to silent mode (display ports side)

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

Samsung Memory BIOS tests (thanks to Heki):

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

In this case, for some reason I wasn’t able to set the clocks via .bat file and I had to split the commands. I set the clocks to 1130/2150, undervolted the GPU to -100mV via MSI Afterburner and added –mvddc 900 to the .bat file.
