Default BIOS Sapphire Pulse RX580 8GB

[R4z0r]

Hi, I am trying to flash my card to the defaultBIOS. I bought it on ebay and the previous owner flashed it to a mining BIOS.

I'm struggling to find the default BIOS for my card. Every one I try in ATIFlash just says "Subsystem IDs missmatch".

How can I determine the subsystem ID? I've tried GPU Z but I can't see this value.



Any help much appreciated!

Ask the seller maybe ?

Thanks, yeah I've sent them a message but no response so far. I was hoping I could just download it but I can't find one that is compatible.

Don't really mess with vbios anymore but back in the day this was the resource of choice: https://www.techpowerup.com/vgabios/

E: seems to be the latest one for the Pulse 8GB https://www.techpowerup.com/vgabios/208710/sapphire-rx580-8192-180719

Thanks, that's really helpful. I'd actually found that file but I couldn't flash it because of the "Subsystem ID Missmatch".

Turns out the previous owner had cross-flashed it so it was reporting a different vendor, Powercolor in this case.

Solution was to run the flash command from the CLI and pass it the force option, recording here in case it helps anyone else.

amdvbflash.exe -f -p 0 {{ bios_rom }}

Where "0" is PCIe location, this can be found with amdvbflash.exe -I.
