Hello mate. If I may continue this topic. I have a very similar if not the same problem.
Under HiveOS I am trying to flash my bios but I can not. "In process VBios bios.rom" and after a while this changes to "Failed VBios bios.rom".
I am doing this with the link bios from techpowerup.
There is sth more with the gpu because I bought this second hand and it came pre-installed with this version of the bios (according to GPU-Z). So the real question is how to fix this in linux, which is not possible in Windows ? If it is a faulty card, which is the possible element to look into ? Its not about the destination - its about the journey. Thank you beforehand.
P.S.
