MSI X870E Carbon / 9950X / 2x48GB - RAM bizzare issues

djubre7 · December 19, 2024, 11:31am

Hey all, I’m experiencing a weird issue I can’t find anywhere happening, so maybe some experienced users here might help me.

A month ago I finally upgraded my old workstation from x99 / i7 5820k / 16GB after 9 years. Also, I finally switched to Linux full time (Cachy OS, still new to Linux) , but this is not as relevant to the issue I’m experiencing.

General hardware info:
CPU: AMD Ryzen 9950x
MB: MSI MPG X870E Carbon WiFi 7
RAM: 2x 48GB 6400 Kingston KF564C32-48
GPU: Zotac NVIDIA GeForce RTX 4060 Ti 16GB
PSU: 1000W Corsair RM-1000i
CPU cooler: Noctua NH-D15 G2
Case: Fractal Design Torrent
OS m.2: Samsung 1TB 990 Pro

Every few days after a restart or shutdown, I’m greeted with a message that the hardware changed and I have to load the default values in BIOS. After entering UEFI, I see that the system sometimes sees 52224 MB RAM, sometimes 6144 MB RAM (wth?!). At this point, I can go on, log in to my OS which indeed reports that I have only 6GB or however much of RAM it detected, or i can clear CMOS with the button on the back of my MB, which makes it see the whole 96GB again, but at the default factory speed of 4800 MTs. So I then need to again set it up to 6400 MTs, enable IOMMU and SVM for the virtualization I plan to play with sometime soon and then restart back into my OS.

As for the BIOS settings, it’s updated to the latest version from a couple of days ago (didn’t help), and the only things I set up differently from factory settings are:

RAM speed (xmp profile 1),
PBO to AUTO (Thermal limit of 85 degrees C - MSI’s setting)
Game boost Enabled
IOMMU Enabled
SVM Enabled

I wanted to know what do you people think it’s going wrong? I tried reseating the RAM, going with integrated GPU, unplugged in and out all the cables… Nothing helped so far. I’ll put detailed system info below. Thanks in advance for the advice .

EDIT: Yeah, if you thought of maybe getting this MB for VFIO with dual GPU’s - pay attention. The IOMMU groups are very well done, but MSI really dropped the ball with the board design. The lower PCIe slot is almost unusable for the secondary GPU unless it’s a single slot GPU (I’m on the hunt for a single slot A4000 atm) because the board has an additional PCIe power cable input which blocks larger GPU’s. I have an old RTX 2060 which I wanted to put there for this purpose, but it wont fit. So your only options would be a riser cable and a case which can fit a second GPU vertically, or a single slot card.

You probably don’t want to enable this game boost thingy, if it is what I think it is

Is the RAM stable at XMP? Have you done some memtest, ycruncher, etc.? Do you get the same issues keeping it at stock?

It is a weird issue indeed, I would expect unstable memory/failing memory training to just not boot or to need another cycle.

djubre7 · December 19, 2024, 12:19pm

Thanks for the quick reply. I haven’t done any of those, as the system behaves (behaved?) really well in day to day work, temperatures at idle are at 46-48 C, and I haven’t noticed the slightest stability issues or crashes. What I described above only happened after a restart or shutdown ( and only sporadically at that, so far maybe 3 or 4 times), never in the middle of a working session.

I will run those later today and report back the results, it will probably be a good additional info.

quilt · December 19, 2024, 12:27pm

Sounds like a memory training issue then. The puzzling thing is detecting only part of the memory, rather than outright failing. I assume you are on the latest BIOS?

djubre7 · December 19, 2024, 12:37pm

Yes, version 7E49v1A1G from December 13th.

Exactly, I’d expect the system not to boot at all if the memory fails or something, but check these out (pictures taken from the previous BIOS version, but look at the reported RAM sizes). And the system will boot normally with these.

quilt · December 19, 2024, 12:43pm

To debug you could disable ‘memory context restore’ and reboot a couple of times to see if it reoccurs? How often does it occur out of 10, 20 boots? Without memory context restore, memory training will be repeated at every boot.

And does it occur at all at stock (non-XMP)?

djubre7 · December 19, 2024, 12:48pm

Let me get to it and report back. I haven’t tried to run it at stock at all, as I purposefully picked this kit as it (supposedly) runs on 6400 by default…

lemma · December 19, 2024, 1:33pm

I’m in that direction as well but the training might be a symptom of LGA overpressure, socket torque, pin(s) that’re a little off, or board or case warp. Or maybe it’s something else. If things around the socket seem fine I’d try I’d try running with one DIMM and then the other.

What did the stress test pass for build acceptance cover? +1 on @quilt’s stability questions and is 4800 picking JEDEC timings?

This is the G2 regular rather than LBC? Also, while P0 looks right, has there been a physical validation each DIMM is in the correct socket for 1DPC?

4800 is correct. 9950X supports to 5600, Kingston provides 4800, 6000, and 6400 profiles. If there was a 5600 profile I wouldn’t necessarily expect the BIOS to take it over 4800 and the problems here might a drop to 4800 anyways.

djubre7 · December 19, 2024, 2:57pm

@quilt
I rebooted around 15 times with “memory context restore” disabled, nothing out of the ordinary happened. I also disabled the game boost thingy.
Interestingly, I recognized now that every time I’ve got the hardware changed message, the boot took longer than normal and that it was probably memory training in the background.

@lemma

… If things around the socket seem fine I’d try I’d try running with one DIMM and then the other.

How do you suggest I test this? In other words, how long should I use only one DIMM, and then how long another? What would be the different expected (wrong?) behavior with one DIMM that doesn’t show up now with 2?

What did the stress test pass for build acceptance cover? +1 on @quilt’s stability questions and is 4800 picking JEDEC timings?

This is the G2 regular rather than LBC? Also, while P0 looks right, has there been a physical validation each DIMM is in the correct socket for 1DPC?

Haven’t done the memtests yet as there was no need - all worked fine in my day-to-day workflow (when this wasn’t happening at least). I’ll test it later and report.

… is 4800 picking JEDEC timings?

Again, where should I check this? BIOS?

This is the G2 regular rather than LBC?

The G2 is regular, yes.

…while P0 looks right, has there been a physical validation each DIMM is in the correct socket for 1DPC?

How should I check this? The DIMMs are in 2nd and 4th slots to the right of the CPU as the MB advised, should I switch DIMM places with one another (not slots, just DIMMs)?

Rant incoming, not related to discussion:

Rant

Is this really a thing nowadays? Well, sh…t since when did the hardware become so damn sensitive? Not in terms of mishandling the CPU pins and such, but like - too tight board warps the RAM slots, so the memory goes berserk, wtf?! Are people aware what kind of treatment old Pentium and Athlon mbs and even my previous x99 could withstand? That thing still works perfectly after 9 years of crappy electricity, thunder strike to my house, insane voltages after numerous grid power outages? Who accepted this as a OK thing ffs, why do we agree to almost zero tolerance parts? What is this now, I feel if I talk rudely to this PC it might take offense and shut down. Who serves whom here?

lemma · December 19, 2024, 3:50pm

IMO running single DIMM for the amount of time likely to show problems with dual DIMM would be a reasonable measure. Total hassle if day to day use needs the second DIMM but, if it’s a bad DIMM, it’s hard to pin down which DIMM might be bad without pulling the good one. Also hard to distinguish two bad DIMMs from an IMC defect but, as buying another DDR kit or CPU to test with is costly, it’s probably useful to try to for hits as to which to replace or RMA first.

{ LGA, DDR5, PCIe 5.0 }, { PGA, DDR4, PCIe 4.0 }, pick one combination of mechanical margin and electrical capability? ¯\_(ツ)_/¯

Not sure it’ll yield useful information but could be interesting to try anyways, particularly if single DIMM’s impractical.

Yep. Or whatever the Linux equivalent of ZenTimings is.

Cool. I’d say there’s need to validate every build.

homeserver78 · December 19, 2024, 3:59pm

Could this be an issue with the SMBus? Like how some people have had half their RAM go invisible (or fan control stop working, or…) after installing enterprise NICs for example. (Possible to work around by convering up the card in question’s SMBus PCIe pins in those cases.)

As I understand it the SMBus is used, among other things, to enumerate hardware at boot up. The Hardware Changed message along with the weird reported memory sizes and the fact that the system has appeared stable during use made me think of the above. Not sure how to trouble shoot it though, if it’s the case (except reseat the RAM which has already been done).

djubre7 · December 20, 2024, 12:20am

Happened just now. Based on this case, we could maybe conclude that the B2 slot has an issue, but there was a case where it was reported that the Total RAM was 6GB, meaning both slots experience something.

I left it on default values now at 4800 CL 39 JEDEC setting, let’s see if it will happen again.

Keeping an eye on this. I have one of these MBs sitting on my shelf along with 2x48 (G.Skill 6000) when the 9950X3Ds are released in a month.

GameBunny · January 1, 2025, 2:47pm

I have MSI X870E Carbon with a 9800X3D and ADATA XPG Lancer RGB 64GB (2x32GB) 6000MHz CL30 DDR5 memory and just before after a simple system restart, it went into a stand still showing 0d in the debug led and the BIOS and not moving at all. Eventually after few minutes I hit the restart button and it showed me

Devices Changed ( CPU or Memory) or CMOS have been cleared ,
Please enter Setupto configure your system.
Press F1 to run setup,
Press F2 to load default values and continue.

I panicked and pressed F2 to continue, then when in BIOS, just reloaded the profile where I just set PBO Curve Optimizer to -30 and reloaded the system which then thankfully booted. I did not notice if less memory was getting showed in the BIOs at that time cause honestly I did not look for it. I will note one thing though that in this same mobo, I was previously unable to detect memory properly y with channel B2 before with Gskill 64GB kit - F5-6000J3036G32GX2-TZ5NRW - till I changed my memory kit to the above. But now for the first time, the above problem happened. Will have to keep an eye out I see to see if this issue reappears. My BIOS version is the latest one of 7E49v1A21 with release date of 20-12-2024.
