Card used for miningi , motherboard burned. Resistance of all lines normal. The card starts normally, all voltage is present. It is not detected. I checked all lines pcie no deviation. There is a ripple on quartz. No movement on pins 2 and 5 bios. Voltage on pin 1 1.8V. Dead core. ??

Check where PCIe PERST# (A11) goes.
It may go directly to the GPU or to some logic ICs/transistirs. Sometiimes thoses ICs are damaged.

Goes directly to the GPU .Card connected second in the riser is also not visible .

Какое сопротивление?

Very low 2 ohm.

So 100% gpu died ??
