EVGA RTX 2080
Dead after an overclock. I pushed the overclock too hard and a DrMOS gave out, shorting to the core rail. Under the microscope the GPU core itself heated up, so the short was in the GPU and the card couldn’t be saved.
Gigabyte RTX 2080
TMON fault, fixed. One DrMOS power stage’s temperature-monitor (TMON) circuit was misbehaving. Each stage has its own TMON line, so I disconnected them one at a time by flipping the capacitor on each line until I found the stage causing the fault. Method from northwestrepair’s Gigabyte 2080 Super repair (how to find half dead DRMOS).
ASRock RX 6700 XT
Repad, repaste, undervolt. New thermal pads and paste, then used for undervolting.
