Hello, Aorus 3090 xtreme model card does not post even though all voltages are correct.When I plug it in with another GPU, the motherboard stays on the GPU error light.That's why I can't test it from mats mods or check seems in windows.I checked the pex gate, there is 3.3 volt and 1.8 volt output.

The only problem I noticed is that the core heats up very quickly. When there is no heatsink, the voltages drop to 0V. But when the heatsink is installed, the voltages are constant.I measured the PCI lanes and there are no broken lines.I am open to all suggestions and recommendations.
