Hello guys,

Anyone with MSI MPG X670E CARBON WIFI motherboard; which M.2 SSD you use considering you don't experiance boot problems (random loss of M_1 or M_2 SSD)?

So far Samsung 990Pro 1TB/2TB and Samsung 980Pro 1TB/2TB has boot problems. I'm considering to get MSI SPATIUM M480 PRO 2TB -_-

Thank you in advance!

Update! Here is an interesting thing I noticed!

As long as I disconnect my 2 Samsung SATA SSDs (1TB and 2TB) it seems the boot problems are completely gone just like that.

I got my MSI SPATIUM M480 PRO 2TB so for now I will just try to use it as a data disk and disconnect all SATA SSDs. I don't wanna do Windows data migration -_-
Update and good news! Setting all M2 slots manually to PCIe 4.0 worked for me! (also, EXPO and MCR is Enabled); around 30 cold boots with no problems.

It seems that MPG X670E Carbon Wi-Fi has a hard time detecting M2 SSD's PCIe generation when set on AUTO during the first cold boot (I remember when it struggled and still booted Windows it was all laggy; probably it decided to go with PCIe Gen 1.0 or something even more limiting).

Hi,
I have the MPG B650 Carbon wifi and I also have many booting problems. Only like 1/3 of my boots the system recognices my SSD in M2_1 Slot and boots correctly. The other 2/3 I have to cicle trough Bios restarts until it randomly recognices my SSD and I can boot windows.

In my case, with MSI MPG x670e Carbon Wi-Fi board, I tried MSI SPATIUM M480 PRO and set it manually to PCIe 4.0 (in BIOS). Such combo did the trick for me. Also, EXPO and MCR is set manually ON. Currently it seems that, in my experiance, Samsung M2 SSD drives is a no-no on MSI boards.

But why does it work in M2_2 and M2_3 slots perfectly. It is just the M2_1 slot that is corrupt

As far as I can guess, there is some sort of possible software / hardware "conflict" during the boot sequence between Samsung M2 SSD and motherboard. P.S. I removed "MSI" part as similar problems have been reported to other brands too, more or less.

That's it. Only MSI's, AMD or Samsung engeneers may know more about it.
doubtful, as theres not really anything in the way from "MSI'.....it's either directly connected to the CPU (M2_1), or connected to the chipset (M2_2 and M2_3).

Samsung's been having issues in general with their NVMe drives with AMD for a while.....occasionally with Intel. I actually stay away from their NVMe drives now.

True. Actually there are reports of other bands having the same / similar issue. I updated my initial post!

I recently upgraded to AM5 and bought the MSI MPG B650 CARBON WIFI mobo, and almost immediately started to have M.2 related issues (not recognised).

My two SSDs:
  1. 1. Crucial P5 Plus - boot drive with Win11 - in M2_4
    2. WD Black SN850X - non-boot drive, only for games - in M2_1

This mobo has four M2 slots. If you wonder why I'm not using M2_2 and M2_3, it's because these slots share bandwidth with the main (!) PCIe x16 slot (the graphics card), lowering it to x8 instead of x16. This is highlighted even in the user manual multiple times. This is not ideal IMHO, and pretty much makes those two M2 slots useless (to me). However, M2_4 is still Gen 4, and although it comes from the chipset, it doesn't share bandwidth with other stuff. And M2_1 is coming from the CPU, and it's Gen 5 capable (not that I'm interested in Gen 5 atm).

I also have two SATA HDDs.

Interesting thing is, my Crucial M.2 drive (in M2_4) is ALWAYS recognised, but sometimes the WD SN850X (in M2_1) is not recognised, and needs a reboot.

A recommendation, which mentions going into the BIOS and manually setting the SSD Gens for your M.2 drives from Auto to the actual Gen, improved the situation.

I'm using BIOS 7D74v19 (latest non-beta BIOS).

Most people who have M.2 problems mostly mention Samsung or WD drives. I wonder what would happen if I would replace my WD drive with something else, e.g. the Crucial T500 (which is similar to the WD SN850X in speed) ?
 
Does that mean that Asus / Gigabyte / Asrock have the same M.2 issues as well on the AM5 platform?
A quick and dirty search suggest YEP they sure do have the same problem

Thanks. So it seems if I would return the motherboard and go with a different brand (as I'm still within the return window), there's absolutely no guarantee the M.2 problems would be resolved (on the AM5 platform).

Which brings me to my previous post. Has anyone tried to maybe replace the SSD to a different brand? It's interesting that my Crucial M.2 SSD is always recognised, but I occasionally have problems with the WD one. It's not terrible, I haven't got any issues this week (since I manually set the two M.2 slots from "auto" to "gen 4" and also removing all unnecessary boot devices from the boot list in the BIOS), but to me personally, it would be much easier to replace an SSD to a different brand than to replace the whole motherboard.

Running your GPU in 8 lanes instead of all 16 makes no real difference in performance I can run my 4090 in PCIE gen 4. using only 8 lanes and lose no noticeable performance

I was previously aware that PCIe Gen 5 x16 featured on the high end motherboards is mostly a marketing trick, because the GeForce 4090 just about maxed out the capacity of Gen 3, so the difference when running on Gen 3 x16 vs Gen 4 x16 is around 1-2 %, but after I've read your message, I Googled around and it seems that Gen 4 x8 is the same as Gen 3 x16, so probably should be the same 1-2% difference, As you said, not noticeable.

As I own the MSI MPG B650 CARBON WIFI mobo, putting an SSD into the M2_2 and M2_3 slots is still not ideal, as they are located around the main PCIe x16 slot for the GPU, those SSDs basically disappear behind the GPU when you insert your big graphics card, and the SSDs heat up when the GPU is used, as they are very close to the GPU (basically millimetres). The M2_4 slot is further away, still Gen 4, and although it's going through the chipset instead of the CPU, the difference is not noticeable.

Hi, did it fail again? I need to buy an M.2 for the MSI X670E Carbon, and I don't want to have any problems.

I'm Using 3 MSI Drives on that board 1 x SPATIUM M480 1TB for boot and 2 x SPATIUM M480 4TB for Storage on that board and had no issues at all.

with AMD Boards AVOID SAMSUNG as they are issues with AMD's Hardware for every Manufacturer currently.

Will MSI update the QVL to prevent people falling into this?

probably not as they tend to leave them Up even though there not Great. think there hoping AMD fix it in there Next Agesa Code they put out but at the moment there a try and avoid at all costs as they have caused nothing but problems for everyone.

Thank you, although I'm thinking of buying the MSI SPATIUM M480 Pro because it's at a good price now, but it doesn't appear in the QVL. For now, I want to put it on the M.2_1 directly to the CPU.
So, do only Samsung M.2 and SATA cause problems?
