i am a miner , i use amd for mining , in case i uploaded the bios mod for eth on my 570 , but lost the original bios file, i need it , where can i get it?
This a good place to find your original BIOS if XFX website doesn't have available the BIOS for your card: VGA Bios Collection | TechPowerUp .
I would try and contact XFX Support to make sure they can't help you first.
There is only one BIOS to download at the link I gave for the XFX - RX 570 GPU Card:
XFXRX 570 4 GB
RS Black Edition
