I have a 4tb WD nvme gen 4 slotted into m.2_2 it's reading a connected speed at PCie 3.0.
I have a 4090 with another 2 tb WD slotted in m.2_1 and its showing 4x4 speeds fine.
Can anyone explain what is going wrong here?

Use slots 3-4-5 or you also will get GPU pcie drop from 16x to 8X, lines on m2_1 and m.2_2 are shared with gpu.

My understanding that my boot on m.2_1 will run 8x8 which is probably negligible with a 4090. Which i'm ok with. may change that one later.
But you are saying that it's splitting it 3 ways as is since i'm using m.2_2 also?

Not sure about your board, but check the manual. On my 690 Hero, the M.2_2 slot only supports Gen 3.

Bios updated and intel firmware updated?

Yes it was doing it because it was the 4090 and the two m.2 in slots 1 and 2 are shared.
Moved them both to slots 3 and 4 and all is fixed. Technically it would have worked with the 4090 and slot and 3
