Question NVME Compatibility

[branth23]

I have a Samsung 980 M.2 2280 500GB PCI-Express 3.0 x4 NVME 1.4 V-NAND SSD that isn't being detected by my Gigabyte B550M DS3h AC when inserted in the M2A_CPU slot. It is however detected normally when inserted into the M2B_SB slot.

The board manual states:
1 x M.2 connector (M2A_CPU), integrated in the CPU, supporting Socket 3, M key, type 2242/2260/2280/22110 SSDs:
3rd Generation AMD Ryzen™ processors support SATA and PCIe 4.0 x4/x2 SSDs-
3rd Generation AMD Ryzen™ with Radeon™ Graphics processors support SATA and PCIe 3.0 x4/x2 SSDs.

1 x M.2 connector (M2B_SB), integrated in the Chipset, supporting Socket 3, M key, type 2242/2260/2280 SSDs:- Supporting SATA and PCIe 3.0 x2 SSDs

I have a Ryzen 5 5600G cpu. According to this, shouldn't I be able to use this drive in the m2a_cpu slot?

Thanks!

What BIOS version are you currently on for your motherboard? Perhaps try and clear the CMOS and see if the issue persists.

Thanks for your resonse. I'm currently on the latest bios version, F17. I will try a bios clear next. Thanks

Update: Clearing CMOS did not work. When drive is plugged into the M2A_CPU slot the bios reports no nvme devices detected. I wonder if this is a limitation of the cpu, although according to the manual this gen of cpu should support it.
