1 out of 2 m.2-SSDs not detected by bios or win11

[Estacado]

Hello,

 

yesterday I built myself a new pc. Everything basically works at the moment except for my ›Samsung SSD 980 M.2 PCIe 3.0 x4 3D-NAND TLC‹ which is not detected by my BIOS or by Windows. I also have a SATA-SSD (SATA-Port 5) and a second m.2-SSD installed which were scavenged from my old rig. Those are detected and work without issues at the moment. 

 

My Specs:

 

OS: Windows 11 Pro (Activated, no issues)
 

Cpu: Intel Core i7-12700F 

 

Mainboard: Gigabyte Z690 UD DDR4 S1700 rev. 1.0 [Current BIOS: F5]

 

RAM: 32GB (2x 16GB) Corsair Vengeance LPX schwarz DDR4-3600 DIMM CL18-22-22 (XMP profile works without issues)

 

GPU: PowerColor Radeon RX 6950 XT Red Devil

 

Drives:

1) 1TB Samsung SSD 980 M.2 PCIe 3.0 x4 3D-NAND TLC (MZ-V8V1T0BW) [The part that is causing issues]

2) WD_BLACK SN750 500 GB NVMe [WORKING]

3) WD Blue SATA SSD 1 TB [WORKING, OS currently installed on this!]

 

PSU: 850 Watt be quiet! Straight Power 11 Modular 80+ Gold

 

I have attached two screenshots from the BIOS and I can provide further details if needed of course. I appreciate any help or advice.

Have you tried swapping the two M.2 drives between each others' slots?

now comes the "Fun" part. where did you plug it into?

 

that means which m.2 slot

which sata plug

 

 

 

why do I ask? some mobos have a problem if you use certain Sata ports with certain M.2 slots

@Speedbird No I haven't tried that yet because it is right below the GPU which is really huge and hard to take off. I will try this if other options dont work out though.

The red circle is the one (Samsung 980) which is not being detected.

 

The green one is the one that is detected and currently working

 

The SATA-SSD is plugged in SATA-Port 5

some motherboards have weird issues if you have more m.2 ssds installed they use the Sata lanes. 

 

you realy should check if you M2. Red circle is placed well. for doing so put it into another slot or reseat it

The top M.2 slot is supposed to be connected directly to the CPU, while the other M.2 slot goes to the chipset. Your M.2 settings or CPU settings in the BIOS might need a look

Which setting in particular do I have to look at? When I check out the NVME-connections, it only shows me the 2nd m.2.-SSD.

I will definitely try this if software solutions dont work out!

If I'm not mistaken, you can change the PCIe version of each M.2 slot between 4.0 and 3.0. you might find some associated settings next to those.

UPDATE:

 

I was able to fix the issue. The ssd was slightly out of place so the mainboard couldn't register it. So @SamClan was right.

Thanks everyone for the help!
