Question BSOD Issues on New Ryzen 9 9950X3D System – Possibly RAM-Related?

[XxROBOTICSxX]

Hi everyone,


I’m experiencing intermittent BSODs on my newly built system and I’m hoping to get some help / insight into what might be causing these stability issues, as of right now I believe it is related to the system Memory but would appreciate any recommendations for testing, etc. Below are the details of my setup and the troubleshooting I’ve done so far:

System Specifications:​

• Motherboard: MSI MPG X870E Carbon Wifi
• CPU: Ryzen 9 9950X3D
• RAM:Corsair Dominator Titanium 96GB (Model: CMP96GX5M2B6800C40)
  • Note: The kit is on the Qualified Vendor List, and it’s validated for AXMP profiles at 6800 and 7000 MT/s.
• Boot Drive: Corsair MP700 Pro SE 4TB PCIe Gen 5 NVMe
• GPU: Nvidia RTX 3090 Founders Edition

Problem Description:​

I’m encountering random BSODs with error codes including:

• SYSTEM_SERVICE_EXCEPTION
• IRQL_NOT_LESS_OR_EQUAL
• PAGE_FAULT_IN_NONPAGED_AREA

When running the RAM at AXMP Profile 2 (7000 MT/s), I experienced BSODs multiple times per day. After switching to AXMP Profile 1 (6800 MT/s), the frequency has reduced significantly (approximately one every couple of days), but the issue still persists.

Troubleshooting Steps:​

• Memory Testing:
  I’ve run MemTest and stress-tested the system using y-cruncher. Both tests completed without indicating any memory errors.
• AXMP Profile Adjustment
  Changing from AXMP Profile 2 (7000 MHz) to AXMP Profile 1 (6800 MHz)
• BIOS Updated
  Updated to latest MSI BIOS ver 7E49v1A3

Questions for the Community:​

1. Memory Kit Issue or Other Component?
   Based on your experience, do you think this might be an issue with the RAM kit itself, or could another component (e.g., motherboard BIOS settings or CPU compatibility) be causing these errors?
2. BIOS/UEFI Tweaks:
   Are there any specific BIOS settings or firmware updates that might help improve system stability with this configuration? I’d appreciate any suggestions on fine-tuning memory timings, voltages, or other related parameters. I'm not extremely familiar with modifying memory timings, voltages, etc, so would appreciate any help or insight in this area.
3. Additional Testing:
   Beyond MemTest and y-cruncher, what other diagnostic tools or tests would you recommend to further isolate the issue?
4. Potential Refund/Replacement:
   Given that I’m within the 30-day return window, I would like to identify and come up with a solution as to weather I should pursue a refund/replacement for the RAM kit and potentially get another kit?

Any insights, diagnostic advice, or similar experiences you could share would be extremely helpful. I’m keen on resolving this issue as I don’t want to run into more stability problems once I start using the system for more demanding tasks.


Thanks in advance for your help!

Well done for getting your 9950X3D to run at 7,000MT/s. I've no idea if this is normal or exceptional, but the maximum frequency shown in CPU World is 5,600MT/s. Anything higher and you may need to tweak the EXPO values if your system is unstable. Perhaps you could try relaxing CL/CAS by one or two clock cycles?

Integrated peripherals / components
Memory controller	Memory channels (total): 2 Supported memory: DDR5-5600 ECC supported: Yes

When I built my 7950X system back in 2023, fast RAM was too expensive for my wallet, so I ended up buying 2 x 32GB Kingston Fury DIMMs running at 4,800MT/s. Although memory prices have improved, I can't be bothered to change the RAM. In any case, programs like Adobe Premiere Pro benefit very little from faster RAM on AMD systems, so it would be a waste of money in my case.

He should just tighten his latencies and change speed to 5600, 6000 absolute max. DDR5 is kinda fussy for speeds over 6000 on AMD systems, intel less-more depends

You've got an XMP kit for an AMD platform. This is generally not good since XMP runs at 1.35V while EXPO (AM5 boards) usually runs at 1.4V (especially Corsair RAM).

Moreover, even at 1.4V it's not easy to have something stable with more than 6200 MT/s with AMD CPUs especially with X3D chips. I would try to set the RAM to 6400 and 1.4V and see if it's stable. If it's not, go to 6200. If still not stable, go to 6000.

I noticed this as well, however I did want to mention that this kit is listed on the MSI compatibility list for this board for 9000 series ryzen, if that makes any difference, the AXMP profiles are running it at 1.4v already, I'm just at work right now, so I can take a look once I'm home.

Even though, it's listed in the supported list on MSI, the modules do not have an EXPO profile and make no mention of being recommended for use with AMD within the listing's specifications at Corsair or Newegg.

That's fair, I appreciate the insight and help. I was under the assumption that if it was on the QVL List under Memory by 9XXX that it was actually tested to run stable using those profiles. I did find the article from corsair (https://www.corsair.com/ca/en/explorer/diy-builder/memory/can-i-use-intel-ram-on-an-amd-motherboard/) and it does state that in practice the memory should work as the motherboard can still read and use the XMP profile data for timings, voltages, etc. And typically will display is as a proprietary name like ASUS Enhanced Memory Profile (AEMP) or in my case MSI appears to use AXMP. But I see it does note that, "you may find that you simply can’t hit the full speed with that kit when paired with your AMD CPU. You should be able to get it working, just not at a fast speed setting.".

Once I am home I will tweak the settings and try to run it as it was suggested at 6400 and 1.4v, see how that goes, in the end I might opt to return and purchase a different kit, this is my first time running DDR5 so I wasn't aware how fussy it was with AMD.

The only differences between an EXPO and an XMP RAM kit are the values saved in the profile that is loaded when you enable EXPO or XMP. AM5 is less stable at higher clock speed and requires more voltages than Intel, so the profiles are set accordingly.

If you set your RAM manually to match the EXPO values you would get from an EXPO RAM kit there is no reason it would not work if it's a kit designed to work at higher speed (you basically downclock it). But in this case you might have wasted money since you paid for a 7000 MT/s kit and have to run it at 6400 or even likely 6200 MT/s.

By the way, you also need to take the timing into account. If you reset the BIOS to default and go directly to 6400 MT/s you might have some problems since the default timing at 4800 MT/s might be too tight for 6400. You might be better to enable EXPO and decrease the clock from there. And if you get something stable at lower speed, then you should be able to lower the timing to reduce latency. For example, at 6200 MT/s you should be able to run easily at CL 32-39-39-102.
