Grab GPU-Z and HWinfo if you haven't yet. Check both tools, focusing on HWinfo in sensors-only mode. In games and GPU-Z's render test, I'd like to monitor power usage and examine PCIe generation and width. In GPU-Z, the ? icon next to the PCIE bus info opens to their render test. HWInfo64 includes a section in sensors-only mode showing data from all accessible graphics card sensors. I'm also interested in seeing the driver version in GPU-Z.
The power supply failed completely. After swapping the motherboard, testing various GPUs and adding RAM didn’t help—no output from the top slot, but everything worked in the lower one. I skipped further speed tests beyond my initial 7900xt timing. I’m trying to figure out why the GPU isn’t running in that slot. It seems the CPU might be the issue, as only the first slot connects to it.
Consider adjusting your CPU cooler. I've experienced problems after over-tightening it before.
