Hello. I purchased this motherboard a week ago and filled most of the ports with parts when it arrived. Recently, I installed another Samsung 970 EVO Plus 1TB on the remaining M2P_SB slot, but it didn’t appear anywhere. I examined Windows (Disk Management, Device Manager, diskpart), then checked the BIOS (I attempted to enable CSM as shown in some videos, but it always displayed N/A for M2P_SB). I assumed the SSD was defective, though it functioned correctly on the MSB_SB port. I suspect the M2P_SB connection might be faulty—my technician pointed out that the first three pins on the left seem different from the others. He suggested using a needle to adjust them, since they appear slightly higher or lower than the rest. I’m uncertain about this method and hope there’s another solution. If I have to wait a long time for a replacement, I’d appreciate your advice or guidance on how to fix it. Thank you in advance! Here’s a photo of a working M.2 port from my old Gigabyte B560M H motherboard for reference. My specs include: OS - Windows 10, Motherboard - Gigabyte Z590 AORUS ELITE AX CPU, Intel i7 11700KF, M.2 SSD (M2A_CPU), Samsung 980 PRO 500GB M.2 SSD (M2B_SB), Samsung 970 EVO Plus 1TB SATA SSD (port 3), Innovation IT Basic 240GB SATA HDD (port 2), Seagate Barracuda 2TB.

Consider removing every other storage device from the system (both SATA and PCIe) and install only one drive on the M2P_SB port. Verify in the BIOS that it is detected.

I considered it, and received some ideas from others too. I didn’t attempt it before since the manual doesn’t mention a single port being available at once. Still, I’ll try this tonight just to be safe.

I also checked the manual and found the same point. My suggestion remains the same because sometimes things aren't as clear-cut. On my mainboard, I encountered an issue with PCIe lanes due to a specific device setup. It's a bit uncertain, but it might help or provide more hints about the problem.

That suggests a potential conflict with installing two identical NVMe SSDs simultaneously. It seems a bit unusual, but unfortunately I lack an additional NVMe SSD for testing, so I’ll follow your advice and share the outcome once you try it. Thank you for the tip!

Sadly, those three pins caused the issue. Even after following your advice, BIOS didn't recognize them. I spoke with the retailer, who told me it would take 40 days before a new or repaired motherboard arrives. I’m considering switching to an SATA III SSD or looking for a technician to fix it. Thanks again for your help!
