Question Lexar 2TB M.2 NVMe SSD not showing up in BIOS

[thel1ron]

I have setup pc with the following specs:
CPU : ryzen 9 3900x.
MOBO : B450 Aorus Pro with bios version f65.
RAM : 32gb ddr4 3200 mhz
GPU : RX 5700 xt
SSD : Lexar 2TB M.2 PCIe Gen4 NVMe NM790, Samsung 500GB 2,5" SATA SSD 860 EVO
HDD: Western digital 1tb

I bought a brand new m2 ssd lexar 2 tb, NVME M.2 SSD not detected as well in windows, have latest bios available, tried to connect SSD to m2a and m2b port, both don't work. Also checked this SSD on my laptop, and it works there.

Welcome to the forums, newcomer!

Which slots are the 860 Evo + WD HDD populating on the motherboard? Per your manual;

page 17~18.

You could try and remove all storage drives, drop the NVMe drive into slot M2_A, clear the CMOS and then see if that helps, bring it up in BIOS.

Hi, ssd and hdd using 0 and 1 slots. Also the problem is that currently m2 slot is on m2a, so all 4 SATA ports should work, but right now work only 1st(0 SATA port). I forgot to mention that I tried already to clear CMOS, but it doesn't help.
UPD:
tried to remove all storage, dropped NVMe to m2_a, and cleared the CMOS, but it didn't help.
