Removed my 3 GPU’s to unplug a USB motherboard header and reinstalled the GPU’s and updated my bios to the latest version. Booted the machine and started Unraid. I could only get the second GPU to work the others had “Unable to power on device, stuck in D3” error.
- Checked the bios menu which said the three GPUs were running at x8 x16 x8 when they should be x16 x16 x8.
- Removed the GPUs , cleaned the contacts and reseated. Now they’re running at the correct x16 x16 x8 speed,
- The bios is still treating the second GPU as the primary GPU.
How do I set PCIE 1 as the primary GPU? Clear CMOS and let it redetect the GPUs? I’m at wits end, this has been like this for a month. Please help
