How do I select PCIE mode for M.2 NVME SSD's? My motherboard is the Maximus IX Extreme.
I have SSD's in slot M.2_1 and M.2_2. Both are detected by BIOS as being in SATA mode. If I go into BIOS, Advanced, Onboard Devices and attempt to force PCIE mode operation then they are not detected at all.
Motherboard Documentation does not cover this issue.
So I did a bit of research and need some users on the forum to confirm this.
