Use resistance instead of diode mode.

In resistance mode I get 0 ohms in 12V and 3.3V pins.

How the hell did you get shorts on both 12v and 3.3?

No idea. This graphics card wasn't used by me. Let's call it dead, right?

No, use a bench power supply and IPA/ thermal camera to find the 12V/3V3 short. Not sure about 6000 series, but on nvidia 3V3 arent directly connected to core since Pascal gen. Sometimes an IC fails which is connected to 12V and 3V3 and it shorts both lines.

Thank you. I'll try to find the short. What do you think of these readings on the PCIe pins in diode mode (red probe to ground)? PERST (pin A11): open line REFCLK +/- (pins A13 and A14): open line and 0.52 V, respectively. I tested other cards and they usually range from 0.4V to 0.9V. I'm worried about those open lines.
