Thank you @eidairaman1 and everyone else. The second vbios you linked worked. I flashed the gpu, restarted, installed amd drivers and it worked. I can reboot with both CSM or UEFI mode. Do I need to check anything else?
Thanks again.
Attached is the bios rom from the card. This was probably used for mining although guy I bought it from said he did not use this card for mining. He does have a big mining rig set up.
Thanks.
Hi!
I just built a new system with the following parts:
msi b450 tomahawk max
ryzen 5 3600
gskill 3200 2x8GB
1 tb nvme ssd
corsair tx550m
sapphire pulse rx 580
All the parts are new except the graphics card which I bought used.
I have installed windows 10 and ubuntu 19.10 dual boot on the ssd...
