Upgraded from M450 Plus to A620 plus now not detecting the M.2 SSD

[Langyboy63]

WD 500GB WD Blue 3D, M.2 (2280) SATA III 6Gb/s SSD, 3D NAND, Read 560MB/s, Write 530MB/s

Is the hard drive it has detected my SSD Samsung Sata and a USB drive but the above is not being detected.

Have tried in both slots, CSM enabled, but nothing shows in the bios, M.2 is enabled.

The MB was over-clocked by SCAN computers so a bit reluctant to mess with the bios to much.

The manual says my SSD is compatible.

Is anyone able to help with this?

Thank you

Hello, @Langyboy63 

Could you please provide the current motherboard model and BIOS version and confirm if you are using any extension cords or adapters to connect the SSD?
May I ask if the issue is that the SSD is not recognized in the BIOS or within the OS?
We recommend checking for SSD firmware and BIOS updates, and then clearing CMOS before checking again.

Thank you.
