285K integrated graphics - artifacts when memory speed above 7200

[cowbawx]

like this other person, i am having this problem. i had a asus board and when i ran a BIOS update it resolved it. i switched boards now though and still have this problem even with the update. please advise. thank you. z890 285k

Hello cowbawx,

I recommend trying the following troubleshooting step in this article to address the issues you've been experiencing: 

• Experiencing Artifacts with Intel® Graphics

Please let me know the results after you've had a chance to try this if not I need to gather some additional information. Could you please provide answers to the following questions: 

1. Can you please run the System Support Utility (SSU) and share the logs with me? 
2. How did you perform the last update? Did you use a device manager-clean installation or Display Driver Uninstaller (DDU) before updating to the latest graphics driver? 
3. May I know the origin of the game (e.g., Steam, Epic Games, etc.)? 
4. Have you updated the game version or any related applications recently? 
5. What troubleshooting steps have you tried so far to fix the issue? 
6. Have you tried rolling back to the previous graphics driver version? 
7. Could you provide screenshots or recordings of the issue so I can clearly see what’s happening? 

Providing this information will help me diagnose the system more accurately and check for available solutions. Thank you for your cooperation, and I look forward to your response. 

Best regards, 

Randy T.

Yes, I tried the above. Same issue. No, I cannot rollback, because this issue has started since i installed the motherboard - today. There is no other driver other than the one I installed. Please let me know how I can get you the system details without publicly posting here and I will do so. This affects Windows and programs, and not any games. What other troubleshooting is there? I know my monitor and cable are OK because it worked on my other board, and older computer. Seems to be firmware related (Graphics, BIOS or... driver). I cannot record this issue, the artifacts are seen when live viewing the screen but screen recording utilities don't catch it. Thank you.

DDR5 Memory

Intel recommends using memory with a frequency between 6000 and 6400 MHz, and we support this recommendation. In our 285K review, we installed new 8200 MHz CUDIMMs, which provide high memory bandwidth but have increased latency. This type of memory was not compatible with the 245K model because it places too much strain on the memory controllers. After installing the CUDIMM memory, the system operated smoothly. However, when we switched from dedicated graphics to the processor’s integrated graphics, we began to see minor artefacts on the Windows Desktop. Running games and benchmarks caused significant screen corruption. Please see the example below:

Experienced reviewers will quickly recognize these artefacts of memory-related corruption. Since the processor's integrated graphics depend heavily on the memory subsystem, the artifacts may be caused by memory running at too high a speed, a faulty memory controller on the processor, or a software bug. Reducing the memory speed to 6400 MHz eliminated the problem. High-frequency CUDIMMs may be placing significant strain on the memory controllers. For an optimal experience, it is advisable to use a 6400 MHz memory kit with low latency timings. This is my personal recommendation. During the initial boot-up, the BIOS performs a memory training process that can take a few minutes. Switching the BIOS to a preferred profile, if compatible, optimizes the memory timings and requires another training cycle. Aside from the integrated graphics issue, the memory kit demonstrated flawless stability otherwise overall and when using a dedicated graphics card. Update: we have replicated this issue on several brands of motherboards, several memory kits and even different processors. Ergo we suspect Intel has some driver work ahead of them, that or the IGP will simply not work with super-fast CuDIMM frequency memory
