Hello,

m.2 nvme (pcie), not recognised in m.2_1.
When installed, its not visible. i have reseated it many times.
Its never visible.
For m.2_1 nvme (pcie x4 capable ssd);
Are there any settings needed to make it visible?

In m.2_2, the ssd is visile no matter what settings i change in bios.
in port m2._1 the ssd is never visible.

Am i missing a necessary change in the bios?

I am running the absolute latest/newest bios.

Thanks for any help

M.2_1 only supports PCIe Gen2 x2 & SATA3 drives. Maybe your SSD won't fall back to Gen2 x2?

m.2_2 is the 2x2 drive.

m.2_1 supports nvme pcie x4.

That is confirmed by asrock, and in the manual.
