Rog Strix B760-A M.2 not working

[Yo_Ryugekiken]

Hello,

I've just installed my PC with :
- ROG STRIX B760-A DDR5
- i5 13600KF.

I installed the NVME SSD from my old PC but none of the 3 slots detects it.

I have installed windows on a SATA SSD, updated the bios to the latest version, installed all the drivers available on the asus site. I've done various BIOS settings tests but my NVME cannot be detected.

I saw that several similar cases were reported but I couldn't find a solution.

Do you have any suggestions?

It's a strange problem. Might be worth trying a complete BIOS reset followed by a complete power down (turning off at the PSU for a few minutes). Some problems seem to be solved by a total power off, so nothing to lose in trying it.

Does the BIOS see the drive, or is it just Windows that can't see it?

Otherwise, have you checked that you have recent MEI drivers, ME Firmware and that the BIOS is also recent? You should have all of those updated to the correct versions for whatever BIOS you are using. Again, not sure if that's the problem, but again worth a look. There have been problems in the past where not updating ME firmware to the correct version before the BIOS could lead to the M.2_1 socket not working on some boards. Once the firmware was updated, the slot would work again. 

My only other idea is to put that NVME drive into another computer, just to be sure that it's working correctly.

Thanks for your reply! I'll try turning off my psu.

My M.2 works fine in my old pc

I did update my bios to the latest version and then also updated the MEI drivers, ME Firmware.

Perhaps a setting to be made in the bios?

Not sure about BIOS settings as I don't think there's a way to disable M.2 ports, but also worth checking all of your drivers against MoKiChU's drivers thread here:

In particular, might be worth installing his VMD drivers if you haven't already

I assume you've installed the chipset and serial IO drivers as well?

John asked if you can see the drive in BIOS. It should be visible on the landing page. Did you check this? Is the drive not displaying anywhere? 

Can you give the part number of the drive?

[Yo_Ryugekiken]

Hi @Silent_Scone ,

No, the nvme does not appear anywhere, neither in the bios or in windows.
My NVME is a Western Digital WDS240G3G0B

That is a SATA drive, I am not sure that any of the M.2 slots support it. The manual says they are all PCIe 4.0 x 4, there is no mention of any SATA compatibility. That would explain what you are seeing.

[JohnAb]

Good spot Prestonian, that would explain it!

[Yo_Ryugekiken]

thank you for your help! There is indeed a problem on the manual supplied with the motherboard which indicates sata and pcie on the 3 slots, but when I download the manual, none of the slots are SATA compatible.

I've just received an M.2 PCIE and it's working properly!

If the instructions had been correct, I wouldn't have had to waste 3 days trying to find a solution...

In any case, thank you for your suggestions, which have been very helpful!

[Yo_Ryugekiken]

Thanks for your advice.
I reinstalled all the drivers including VMD drivers and Intel Serial IO and still nothing...

I wonder if there might be a conflict with the Windows 11 install on this NVME.

I'm going to get another new NVME to test.

I've also contacted ASUS support just in case...
