Hello. I hope someone can help. I built my system a week ago and other then this issue rearing its head everything has been working very well indeed.

I find that on every second or third boot into Windows 11 my M2_2 NVME, Samsung 990 Pro 2TB is not detected. The primary M2_1, Samsung 980 Pro 1TB containing the OS, is always detected fine. I tried booting into the bios 5 times last night and the 990 Pro always shows, possibly ruling out a slot connectivity issue?

I'm more inclined in believing this is a BIOS bug or a problem with the 990 Pro SSD.

Try swapping the 990 and 980 Pro drives. If the problem moves, it's probably related to the drive, if it still occurs in the M2_2 socket, it could be the socket or bios, and if it disappears, it's probably bios related.

I've swapped out the drives and no joy. I believe the problem lies with either my bios or with Windows 11 itself, as sometime the system will get stuck in a boot loop until I perform a hard shut down and restart. Windows log shows a hardware issue with live kernel event 117. It shouldn't be my GPU as this was working perfectly fine in my system from a week ago, which was a Z390 with an i9-9900K. After being on an intel platform for many years, I'm beginning to regret moving over to AMD.

The more severe problems may have been caused by swapping your boot drive (980 Pro) into the problematic M2_2 socket. If you put them back in the original locations, does everything work as before with only the 990 disappearing periodically?

Yes, the same as before. I might try reinstalling windows.

If both the 990 and 980 drives had problems in the M2_2 socket, it sounds more like a defective or contaminated socket rather than a Windows problem. Is it possible to inspect the socket for bent connectors, or contamination?
As a work around, you could put the 990 Pro in the M2_3 or 4 as they're both supposed to be PCIe 4.0.

Do you have the latest firmwares installed to the Samsung SSDs via Samsung Magician? Check for that.

For troubleshooting, you can take out your 3090 to reduce the complexity. The AMD has integrated graphics which might be better until we find out more.

Your BIOS is the newest version? If not, try the latest beta, https://www.msi.com/Motherboard/MPG-X670E-CARBON-WIFI/support

Hello and thank you. I do have the latest bios installed. What's weird is that I tried a little test, whereby I booted into bios 5 times and the drive I'd always listed and present. It's only when booting into Windows that this happens. I know there's another BIOS in beta stage and that should get its final release soon. Magician software updated my 990 Pro firmware straightaway. This is a little perplexing as I am quite a PC enthusiast and gamer and usually figure these things out. Maybe it'll help.

I'm also less inclined to believe its the SSD that's failing as once it boots into Windows it never becomes undetected and I can play games off this drive for hours.

Try the beta now. Things like this is exactly what a beta can be good for. Firmware for the SSDs is up to date too?

This might be the root of issue.

My Samsung SSD's are both running the latest firmware. I've reinstalled Windows and refreshed the BIOS. So far of around 7 boots the 990 Pro has been detected in Windows. However, I got a boot loop which then sorted itself and went into Windows. Error log file stated a hardware issue caused this. My strongest feeling is the current BIOS has some bugs. Once I'm into Windows, the system works very well and is smooth, with no BSOD, crashes or restarts and my games work fine.

I would run some stress-tests. Waiting for BSOD/crashes etc. is not a way to verify system stability. I always start with the tests i mention in my RAM thread under 5), namely Memtest86, then some Windows-based RAM test, Linpack Xtreme, and Prime95 Torture Test is also good for finding errors.

Just thought I'd update everyone and especially as you've all been so helpful with your fault rectification suggestions. I suspected either a corrupt bios update or Windows 11 installation after I built the system just over a week ago. I remembered the USB drives I used were not the best and were sometimes not detected when connected to a PC. So I made sure to use a reliable 32gb USB flash drive and reinstalled Windows and BIOS. After at least 10 windows restarts, the drive is always detected now.

The new worry is about the CPU overheating and blowing up, as has been reported across the media recently.

Folks, I'm back again. I think I was wrong with the slot I previously put my M.2 ssd in.

I have just done some further fault finding and since moving the 990 Pro 2tb ssd into M2_3 slot, I no longer get any issues detecting this drive. I believe my M2_2 slot may be defective. Isn't this strange, as my M2_1 which has windows 11, using a 1tb 980 pro, never has any detection issues. I wouln't think such an expensive board would have such a fault.

Faults can happen sometimes I am running Four MSI M480 1TB M.2 on the same board as you and all get detected all the time I would suggest you explain what is happened to your supplier and apply for a replacement under warranty

I run into this thread by looking up my issue which seems 100% identical:

MSI X670E Carbon WiFi
7700X
2x Samsung 990 PRO 2TB in primary and secondary M.2 slots
Windows 11

3rd and 4th m.2s are not populated, no SATA drives

SSD in secondary slot [d:] is not detected approximately every second/third start
Reboot always helped so far. Once rebooted and drive is present, there is no performance or stability issues of any kind.
I do keep up with all stable BIOS updates and Samsung's SSD firmware, there was at least one SSD firmware update since I started noticing this issue
I did not move SSD's around yet

First and second M.2 slots on this board are PCIE 5.0 directly from CPU
M.2's three, and four are PCIE 4.0 connected through chipset

Given this discussion, it seems to point to either some hardware issue with secondary M.2 slot on those Carbon boards or some unresolved BIOS bug

Old post but I am also experiencing the same issue. On my first board, it was every 5 or so restarts I'd see M2_2 not detected. I took everything apart and replaced the mobo but I'm still seeing issues with the M2_2 slot, although it's less on this new board.
Thought I had fixed it but it just popped up again this morning.

The issue occurs in the bios too so it's not the OS, and I'm on the latest beta firmware. Hopefully a new bios firmware can fix it but so far (fingers crossed) it hasn't caused any real issues. Sleeping the computer and waking it up can cause the drive to disappear or get reconnected, so sometimes it just fails to power up.

edit: oh, also, all my m2 slots are populated (2x 990 and 2x 960) and I've made sure the issue wasn't the drives so it's not like not using the m2_2 is an option. What a pain for an expensive board. I guess I could give my 960s to my wife and just use m2_1 and m2_3 but what a pain.

Count me in as a customer with the same problem.
My rig:
MSI MPG X670E CARBON WIFI running on BIOS 7D70v18
Ryzen 7 7800X3D CPU
32 GB of DDR 5 G.Skill 6000 CL30 Trident Z NEO (F5-6000J3038F16GX2-TZ5N)
MSI GTX 1080 Ti Gaming 11G graphic card
Seasonic PRIME TX-1600 ATX 3.0 power supply
Samsung 1TB NVMe SSD PRO 990 in slot M.2_1 with Windows 10 Pro on it.
Samsung 2TB NVMe SSD PRO 990 in slot M.2_2 for games.
I assembled it 2 months ago.

As I mentioned it in a post of another customer, the NVMe SSD in slot M.2_2 is not detected during half of the cold boots. It then needs a restart of Windows (or sometimes several restarts) to finally show up. It's an annoyance I would like to see disappear with all my heart.
Changes in the BIOS like M.2-2 connection from AUTO to GEN 5 then to GEN 4 didn't help.
POWER DOWN option ENABLED and MEMORY CONTEXT RESTORE ENABLED did not resolve the problem.
Reseating the SSD in slot m.2_2 was to no avail.
