I have several hundred 30 series cards and almost all my Strix and 3080 FTW3 have this issue, they will be mining fine on my Asus Z390-P and as I am phasing that board out for the Biostar Expert/Pro 2.0 boards I find my GPU tend to “die”
They work completely fine, board swap, and then they just show 0 GPU
When I remove the GPU to my Windows test bench the GPU will boot but no longer post. I have to assume some driver issue is happening but how am I to fix these issues if the GPU shows up empty in the PCI Slot on my Windows machine?
