Hey folks! Hoping someone will have some advice. I just cannot get my GPU to run at x16, only x8.
Z690-E Gaming Wifi Motherboard, 12900KS CPU.
Originally I had NMVE drives (both Firecuda 530 2TB) in M.2_1 and M.2_2. I figured this was the issue and moved those drives to M.2_2 and M.2_3.
GPU is a 4090, though I've also tested with a 3090 I still have.
BIOS is 2004 because 2204 gave me some stability issues.
No other PCIE/PCI slots in use.
Have tried clearing resetting BIOS config via the in BIOS option and the physical button on the back.
Have tried cleaning and re-seating the GPU/slot.
GPU is for sure in the top slot.
In the BIOS, it only picks up the card at x8, obviously this is what I see in Windows too (via GPU-Z or the Nvidia Control Panel).
I know there is probably (definitely) no/minimal gain to be had at x16... just makes me crazy that it's not "correct."
I probably will not mess with removing the CPU... that is probably too far for me to go on this issue.
Anyone have any other ideas? Something I could be missing?
Thanks in advance.

I had the same issue with two of these motherboards:
Both RMA'd and now working correct at X16
