I have a 44lane processor and one GPU which is in slot 1.
So the PCI-e lanes should be according the manual is x16, x8, x8, x4 (x8 if no usages of U.2)

Now I have the DIMM.2 populated with two M.2 sticks, but only one is readable.
I have two Intel 900ps in slot 4 and 5 which should both be x8.

I can use my PCI-e and one of my two m.2 but not both. The second won't be recognized.

So I tried to populate PCIE slots 1, 2, 3 and leave four blank so it can use the full x8 for the Dimm.2 drives.

I still can see only one AND slot two on the PCI-e lane which should be x8 is unrecognized.

If I use the M.2 under the board, then the U.2 is activated and the last slot is turned off.

So the only thing I haven't tried is to pop in my m.2s into my hyper 16 and try the hyper 16 in the other x16 slot and try the other two Intel drives on the slots 2 and 4.



I have the lanes so it has to be a BIOS configuration or someting else.

Help?
