MAG Z890 Tomahawk, Ultra 7 265k,Gskill 32GB (2x16GB) System Stabilite Test Hardware Failure (Memory)

[Gwynbleidd White Wolf]

Hello everyone,
My system is as follows:

• Motherboard: Msi MAG Z890 Tomahawk Wifi - AMI BIOS7E32v1A90 Installed
• Processor: Ultra 7 265K
• RAM: Gskill 32GB (2x16GB) Trident Z5 Black DDR5 6400MHz CL32 1.4V
• PSU: Asus Rog Strix 1000w Atx 3.1 Pci Gen 5
• GPU: Zotac RTX 5070 Ti
• Windows 24H2

Ultra 200S Boost OC enabled
XMP enabled (CL32-39-39-102 1.40V Profile)
RAM Mode: Performance



When I run stability tests (AIDA64 Stress Memory Test, Prime95 Blend) on this system, I get memory-related errors. The memory modules are officially listed as compatible with the 200s boost overclock profile.

Gskill F5-6400J3239G16GX2-TZ5RK RAM modules are listed as compatible with the 200s boost profile in the Intel® XMP 3.0 Memory Datasheet and are also listed in the MSI 200 series upgrade list. Interestingly, before using G.Skill RAM, I had ADATA XPG AX5U6400C3216G-DCLARBK RAM when I first built the system. I initially encountered memory errors with them as well. Thinking the problem was with the memory, I switched to G.Skill RAM, but the problem persisted.

RAM modules from both brands are listed as compatible with the MSI 200 series Boost.



Sequence of events

a) This issue occurred on the evening of September 22, 2025.

Around 10:00 PM, my computer was working normally. I was watching a video on YouTube with the Edge browser open. While browsing forums on a different page, the system crashed. The system restarted, and the system crashed a second time under the same scenario. I started stability tests. I got a hardware error in the memory tests.

I ran the Windows 11 24H2 sfc /scannow test and found no software issues on the Windows side.


b) On the evening of September 23, 2025,

I came home from work.

• AIDA 64 CPU and Memory Stability Test: 45 minutes
• Windows memory recognition test
• Memtest86 4-phase test 2 hours 15 minutes

I did not encounter any hardware errors or interruptions to the test.

It is unknown whether the issue stems from incompatibility with the Intel 200s profile, MSI BIOS, or Windows, but there is an incompatibility problem. This causes random BSOD errors. If it were hardware-related, I would have definitely encountered an error during last night's 4-hour test.

Myself and other are having the same problem. I've tried 4 different sets of ram, all on both the intel and msi list it happened with all of them. Couldn't get a ticket to submit and the online chat was no help at all, so hopefully they are aware of the issue and working on a fix. The only temp fix I've found is turning off the Ultra 200S Boost OC and unplugging the the power supply for a few minutes and the ram issues go away. I tried setting the ram extension to performance and disabled and it still happened. Also setting the ram to high efficiency mode will cause the ram error even with 200s boost disabled. So may need to set the ram extension mode to disabled as well until they hopefully get a fix.

Last night, I ran Windows memory recognition, memtest, and AIDA64 Extreme CPU and memory tests for 3 hours, and interestingly, I didn't get any errors. I hope MSI is aware of this situation. There is a serious stability issue; the system is absurdly giving a blue screen for no apparent reason. If it were hardware-related, I would have definitely gotten errors during last night's tests.

This is the first time I've encountered something like this.

I hope MSI is aware of this situation.

Have you tried to set Memory Extension Mode to [Disabled] and test again?

I've tried 4 different sets of ram,

Could you provide RAM sticker like below?

Photos of the two RAM modules I had issues with are attached.
When I first set up the system, it had XPG RAM modules. Two days after installation, during daily use, the system crashed with a blue screen error due to memory issues. I purchased Gskill RAM modules because they were compatible with the Intel 200S Boost overclock profile.

As a result, in September 2025, I encountered undefined memory-related errors with both RAM modules.

By the way, both RAM modules are SK Hynix A Die.

Does system run fine without errors when Intel 200S Boost OC and Memory Extension Mode are [Disabled]?
Or, have you tried to ONLY enable Intel 200S Boost? (which should work without errors)

Hello,

This isn't something that happens all the time, which is interesting. I explained the sequence of events in the first post.

The PC displayed a blue screen error during normal daily use. The next day, in the evening, heavy testing was performed under the same conditions, and no errors occurred.

There is an incompatibility issue, but I don't know if it's on the Intel side, the Microsoft side, or the MSI side. Because if it were a hardware error, I tested it for 3.5 hours on the evening of September 23rd, and it didn't give any errors. After the blue screen error I received on the evening of September 22nd, I got a memory error in the stability tests, which suggests it could be something related to the memory, but when you run a memory test under the same conditions one day later, the system doesn't show any errors.

Very interesting.

The 200S Boost overclocking profile is enabled because Intel promises it works flawlessly. The motherboard is already powerful, so there must be a software issue at play.

MSI needs to investigate this situation, as others have also encountered similar errors.

I'm having the same crashing issues waking up from sleep. New z890 edge Ti mobo with a new 270k chip.
So, to be clear, my options are wait until a BIOS fix and until then either don't run 200S Boost or don't have my computer sleep?

(Or spend $1,000 on new more compatible RAM.)

If you have enabled Intel 200S Boost, I would suggest not to adjust any other RAM OC related options in case the system becomes unstable.
