I did some investigation of the BIOS files that are on techpowerup. Some of the branded ones are duplicates of what appears to be the stock AMD BIOS, which is this one: https://www.techpowerup.com/vgabios/209475/amd-radeonvii-16384-190211-1
All but one of the others didn't pass RSA signature check, so I think they're illegitimate:
Code:C:\Users\Human\Downloads\atiflash>amdvbflash.exe -rsa AMD.RadeonVII.16384.190211.rom The result of RSA signature verify is FAILED. C:\Users\Human\Downloads\atiflash>amdvbflash.exe -rsa AMD.RadeonVII.16384.190211_1.rom The result of RSA signature verify is PASS. [This is the BIOS my ASRock card has as stock.] C:\Users\Human\Downloads\atiflash>amdvbflash.exe -rsa ASRock.RadeonVII.16384.190119.rom The result of RSA signature verify is PASS. [This is the only older UEFI-enabled BIOS. I tried it, but didn't help my issue.] C:\Users\Human\Downloads\atiflash>amdvbflash.exe -rsa MSI.RadeonVII.16384.190211.rom The result of RSA signature verify is FAILED. C:\Users\Human\Downloads\atiflash>amdvbflash.exe -rsa Sapphire.RadeonVII.16384.190211.rom The result of RSA signature verify is FAILED.
@MACAK, could you do me a favor and dump your VBIOS with GPU-Z and post it here? I'd like to rule out this issue of alternative BIOSes before I try out an upgrade to Catalina.
Do you have instructions on the process?
