ASUS B650PLUS Unable to detect 2nd GEN4 M2 stick

zappa69 · 15 Dec 2023 at 22:01

Hi.

I have just added a 2nd M2 PCIe NVMe M2 card and its not being detected in windows or the BIOS.

I'm running the latest BIOS 1811 on a ASUS B650PLUS mobo

The 1st card is located in the nearest slot next to the processor (this is working fine)
The 2nd card is located in the bank of 2x M2 slots in the slot nearest the rear of the rig.

Does anyone have any suggestions? Apologies in advanced if I haven't provided enough info

Thanks
Mat

It does appear in Disk management at all. Does appear in Device Manager. Doesnt appear in BIOS ?? I just don't get it?

Thanks for the advice. Still no joy.

I've reset BIOS.
Swapped M2 Slots
Still cant see if BIOS or Device Manager or Disk Manager.

SSD is brand new and unformatted.

Ok so I've now inserted the "faulty" card into the slot that had my M2 card that has the OS on it and the "faulty" card is still not detected in the known working M2 slot.
I put the OS M2 card in one of the other M2 slots and it worked fine and booted up.

So I know that at least 2 of the 3 M2 slots are working fine with the Kinston OS M2 SSD.

I can only presume that the new M2 card is faulty?

Sorry Model of SSD is: SK hynix Platinum P41 PCIe NVMwe M2

Ok so I've now got a replacement M2 and exactly the same thing. BIOS, OS etc doesn't see drive. Surely someone has got this drive working on this Mobo?

Can you back flash to 1807 please and see if it gets found then ? loads of reports of some of the AGESA updates from AMD is not distributing PCI-e lanes correctly which was showing itself as missing m.2 drives / slots, just have a look on the X670e ROG resource forums thread.

1811 for you/1801 for me never even made it out of beta for a lot of the ASUS x670e motherboards, my Gene included. https://docs.google.com/spreadsheet...meeDbEHYP-FHYW-PMyOk/edit?pli=1#gid=522016589

There is also a beta bios here, for my Gene this fixed all the problems I was having, make sure you select the right board, B650 boards is the 7th post down by Safedisk: https://rog-forum.asus.com/t5/amd-600-series/x670-resource/m-p/978877/highlight/true#

I have flashed Bios back to 1807 and still no detection of M2.

Should I try one of these below ? If so which one and is the flash process the same?

Many thanks

Any sata drives plugged in as well?

Nope no Sata drives

It is possible both M.2's you've bought are faulty, but unlikely. Do you have another system that you could try the drive in at all?

Yeah it IS possible, but as you say unlikely. I don't have another system with M2 slots.

Is the replacement the same make and model? Might be some sort of strange compatibility issue. Rare these days but it does happen, often solved by a SSD firmware update or BIOS update.

As Kirby Wurm above suggests you could try it in another system or an external usb enclosure.

Assuming you sourced those beta BIOS updates from the Asus forums then any of them should be fine. Obviously if you have the WIFI version of the board those are the ones you should be using or if you don't use the regular ones. The flash process should be the same through the EZ Flash option in the BIOS.

I tried this one TUF GAMING B650-PLUS Beta Bios 2204 - but still not detecting M2? Are there any specific settings within BIOS that need configuring? Drivers ? I'm just clasping at straws here
Yeah the replacement is same make and model and there doesn't appear to be any firmware on their site??

If it isn't showing up in the BIOS at all then there isn't a lot you can do. It seems you've already ruled out the board by moving the OS drive to the other slots which prove they work so it all points to the new M.2 drive being the issue. Either both are DOA (not impossible but unlikely) or they have some sort of compatibility issue with your specific combination of hardware.

I don't think your board has M.2 slots that share bandwidth with anything else so there shouldn't be any settings to tweak. It should just work really.

Honestly at this stage just get a different brand / model of SSD from a reputatable source and see if that works. That will be the simpliest solution and then if that works just return the SK Hynix drive.

Yeah I think you are right. I've not got a lot of options at this point. I'll get a Kingston M2 as that's what the OS is running on.
Thanks for all the help and happy new year.

I have now replaced the Hynix M2 SSD with a Crucial T500. It's now being detected in BIOS and OS when I 1st place the card in a M2 slot. I can install games on the drive no problem. However when I reboot the M2 SSD is no longer being detected in BIOS and therefore OS. If I change the slot that the M2 SSD is located it will detect it in BIOS and OS upon 1st boot. If I then reboot the machine it isn't detected in BIOS and OS? WFT??

Are you back on a stable BIOS version?

Some Asus boards got a BIOS update a few days ago so might pay to check if there is one for yours.

Thanks, just checked and there is a 2214 new version out. I'll get that installed and see if that fixes it!

zappa69 · 5 Jan 2024 at 19:08

Ok so updated the BIOS to 2214 booted up and no additional M2 SSD detected. shutdown, swap M2 slot and reboot. The drive is detected in OS etc. Same pattern as per pre BIOS update.?

Speed said:
So this happens with all the M.2 slots?

Well. I've only tested on the 2 free slots. Not the slot nearest the cpu which has an M2 with the OS on. This slot never has any issues.

From what I understand two of the slots use CPU PCIe lanes and one uses the chipset PCIe lanes. The two CPU ones are the top and the bottom left. So if you are swapping between the bottom two slots that kinda suggests a board issue rather than a CPU problem as logically if it was the CPU the bottom right would be unaffected.

Assuming a BIOS reset with the battery out and power cord disconnected from the PSU for 5 minutes doesn't help I'm kinda out of ideas. I would suggest contacting Asus support to see if they have anymore suggestions or RMA / replace the board.

I am not entirely sure how the lanes are configured on my mobo. Not sure this diagram tells you either. But I agree I think its deffo a mobo issue and I'll be forced to RMA (although I think the board is over a year old so not sure if I'll get a free replacement?)

I was talking specifically about your board. If you scroll down from that diagram to page 1-4 it explains how they are divided.

Asus boards should come with 3 years warranty so you'll be covered. Might be quicker to go through the retailer but see if Asus support have any other suggestions first or maybe make a thread on the Asus forums as some staff / very knowledgeable people lurk there.

oh right I see. Thats good about the warranty (I bought via Amazon so I guess they'll be ok?) thanks for the advice
