Hey, one of my friend has an rx 6900 xt that doesn't get any video out but is detected in device manager and gpuz with error 43 in device manager when using integrated graphics. I think it's a vbios issue since the gpu is detected and throws error 43 but i can't find the vbios chip on it. Where is it ? I have a bios flasher so i can force flash a new bios even though the gpu doesn't output anything. Here are pcb pictures from techpowerup.
