[SOLVED] Samsung M2 SSD not showing up after enabling A-XMP.

[nkneshev]

I swapped out my motherboard recently(old one was MSI B450M pro-vdh plus), however after enabling A-XMP(Profile 2) so my RAM could run at 3200mhz, instead of 2400mhz my M2 SSD just disappears, it's like the board does not recognize it. On my previous board it worked just fine with A-XMP enabled.
I've put my other 2 SSDs(non-NVME) into SATA ports 1 and 2. Tried switching from CSM to UEFI boot, but the issue still persisted. Interestingly, during some boots with A-XMP enabled the SSD randomly showed up, but was gone on the next restart.
System specs:
MSI B450 gaming plus max
Ryzen 7 2700
Kingston Fury Beast 2x16GB@3200mhz
Aorus geforce GTX1080 xtreme edition 8gb
Zalman ZM600-LXII 600W
The M2 in question is this one: https://semiconductor.samsung.com/us/ssd/pc-ssd/pm9b1/mzvl4512hblu-00b07/

Hope someone has an answer to this, because I couldn't find a definitive solution online regarding this issue and it's driving me nuts.

Welcome to the forums, newcomer!

Did you reinstall the OS after the motherboard swap?

That is a PSU I wouldn't consider a PSU ad you should look into replacing it ASAP.

What BIOS version are you currently on for your motherboard?

Hi!

I haven't done a reinstall, but I am considering it. As for the PSU, I will most likely replace it once I start my new build, but if it really is that bad I might get a new one for my current setup and just move it to the new one later.
I updated my BIOS via m-flash to the newest version available for this board. 7B86vHN2(Beta version)

Does not show up where?...... in the bios or in windows?

I haven't done a reinstall,
That's the first thing you do after a motherboard swap.

It shows up in both BIOS and Windows, but only if A-XMP is disabled from BIOS.

Guess that's what I'll be doing then, will get back with an update if this fixes the issue.

Did you clear the CMOS after verifying your BIOS was successfully flashed to the latest version?

It shows up in both BIOS and Windows, but only if A-XMP is disabled from BIOS.

If you enable xmp does the bios still see it?

I haven't tried that yet, no.

When I enable XMP in the bios the NVME still shows up, but its gone in the BIOS and windows after saving changes and rebooting.

If the bios does not see it that's a good reason why windows does not see it.....work on the bios.

It seems that clearing the CMOS solved this. A-XMP enabled + UEFI boot and my NVME is now showing up in both windows and BIOS consistently! Restarted multiple times just to make sure. Thank you!
