The PCIE lanes from slot M2_1, come straight from the CPU, so I don't think it is a board or BIOS problem

2400G, runs at PCI Express Revision 3.0, 5800X, runs at 4.0
But NVME can only be used on M2_1, because the other M.2 slot, supports only SATA]]> Mon, 13 Mar 2023 23:41:33 +0000 https://forum.asrock.com/forum_posts.asp?TID=25560&PID=103999&title=asrock-b450m-steel-legend-not-detecting-m2-nvme#103999 https://forum.asrock.com/forum_posts.asp?TID=25560&PID=103783&title=asrock-b450m-steel-legend-not-detecting-m2-nvme#103783 Author: barlap

Hello, recently i updated my pc to Ryzen 7 5800x from:
ASRock B450m steel legend
Ryzen 5 2400g
2x hdd 1tb each
X1 ssd nvme 248gb for windows
Rx 570 8gb
650w power supply
32gb ram

After updating i also upgraded the bios version from 2.90 to 3.60 as it' s mentioned on the asrock website.
After updating the windows ssd is not detected any more and the pc take a very log time to boot when the ssd it's present in the m2 slot.
I tried to take out the ssd and connect one of my old sata 3 ssd and and everything went ok i even installed a fresh windows to check.
Has anybody any ideea about how to make the nvme slot detectable again?
