I have a 6800xt and am getting an error code 43 message. I've been running the GPU in tandem with another one in order to trouble shoot. I've tried a number of different fixes including removing and reinstalling drivers, reinstalling windows, and replacing hardware components. When installing drivers using AMD Auto-detect tool, the software recognizes the GPU. However, when I start up Adrenaline, Adrenaline does not recognize the GPU. I checked the GPU using TechPowerUP GPU-Z. GPU-Z also recognizes the GPU, but it does not load any of the bios settings when the problematic GPU is selected. It shows zeros in all of the relevant fields.
I considered trying the AMDBVFlash tool to reinstall the bios, but it does not recognize the GPU.
I'm trying to find out if there is a straightforward solution to this problem or if the GPU is gone.
