Hi all,
I've been working through getting a second GPU enabled on this motherboard and having some issues.
Things I have done:
* Determined PCIE4 is disabled due to M2_1 in use
* Moved NVME to M2_2, which didn't work
* Updated BIOS to 10.08
* M2_2 now working with SATA3_3 & SATA3_4 removed and "Force m2_2" enabled
* PCIE4 still not working
* Changed bios setting for PCI Express Config to 8x8, didn't work
* Changed bios setting for PCI Express Config to 8x4x4, didn't work
Is there some other setting I am missing in the bios?
From what I understand, my current hardware config should support PCI 3x16 in the PCIE2 slot and PCI 3x4 in the PCIE4 slot.

Bump.
Anyone know why it might not be recognized with the NVME drive moved to the proper.slot?
