OK so I can't seem to figure this one out. While I was going through the BIOS I noticed my GPU is running in Gen 3 x8 not x16. I looked through the manual and for my 7820x I have 28 lanes available with this motherboard, I have my GPU plugged into PE2 and in the manual it says it should have x16 lanes from CPU, I have also an 80mm key-m m.2 nvme ssd in the slot below PE2 and that according to the manual only takes 4 lanes from CPU and I have under the I/O shield a Key-E 32mm wifi card that takes 1 lane from PCH.... Yet even with leftover lanes for the cpu I still cant get my GPU (an EVGA 2070 xc) to run in anything but Gen 3 x8
I have updated my bios to the most recent 1.28
I have cross referenced this with GPUz and it also shows Gen 3 at x8 even under load
As a Last ditch effort I also reinstalled windows and reset the bios, same issue, no change.
Can anyone help? I have searched all over but can not find a solution.
Edit: If someone would like to see if maybe I just missed something here is a link to the Manual,
