Two rigs work perfectly fine with any registry edit, however I have one rig, where any reg edit i TRY (no matter be it 0.95mV on core, 800MHz on mem or literally anything) will lead to one GPU ending up with Error 43 once disabled/enabled. Now, this could... mean the card is DOA. The problem is, the exact same card mines just fine with stock registry and no edits what so ever.
All the components are identical on every rig. Does anyone please have any idea?
