285K integrated graphics - artifacts when memory speed above 7200

[Strebor]

ASRock Z890 Steel Legend WiFi (BIOS 2.11.AS01)

285K

G.Skill F5-8000J4048F24G x2

990 Pro

Seasonic Prime Titanium 750W

Windows 10 64-bit 

Running this system with only the integrated GPU on the 285K at the moment. Memory is rated to run at 8000. However, when I set any value above 7200 (via XMP profile, including voltage adjustment to 1.35, and auto-timings) then I get small graphical artifacts across the display after booting into Windows. The artifacts increase in frequency the more programs are running or with a heavy load on the system.

When I set the memory to 7200 or below then the artifacts are completely gone, and system is completely stable.

Troubleshooting I've tried so far:
Removing RAM sticks and trying 1 at a time in slot 4, same result as when slot 2 and 4 are populated together. Both individually display artifacts above 7200, and both stop displaying artifacts when clocked down to 7200.

Tried various minor voltage increases to other CPU sub-systems, no effect.

Heavily loaded the system at memory speed 7200, completed several memory tests with no issue.

Tried with all CPU settings at stock, same results.

Tried with CPU ring bus at 4000, same results.

Tried Gear 2 and Gear 4, same results.

Tried a second HDMI cable, same results.

Apricate any guidance.
Thank you,
Glenn

Hello Strebor,

Thank you for posting in Intel Communities.

I'll check on this and will post an update once it's available.

I have exactly the same problem, and I don't think this is something that happens randomly.

My platform is Intel 285k + Gigabyte Aorus Z890 + 24GBx2 Dual Hynix M-die 8000 RAM. When I use the XMP default of 8000MHz, I get very small artifacts on the screen, which increase as the load increases. When I reduce the memory to 6800MHz, there are no issues.

Additionally, when I connect my discrete GPU, a Gigabyte 4080s, and use it to drive the monitor, there are no issues. However, when decoding or playing videos, the system uses the low-power Intel 285k integrated GPU (iGPU) for decoding. In these cases, I randomly get green screen artifacts, and the iGPU load suddenly spikes to 100%. But this doesn’t happen every time; usually, playback works fine.

To summarize:

1. When using a discrete GPU (DP cable to monitor) and using the iGPU for decoding while gaming with the discrete GPU, the iGPU unexpectedly spikes to 100%, leading to occasional green screen artifacts, but the system UI remains fine.
2. When using the discrete GPU (only for gaming) and connecting the display via Thunderbolt, small white artifacts randomly appear on the desktop, especially when moving windows. These artifacts increase with load, but lowering the memory frequency to 6800MHz resolves the issue.

Please help solve this, or else the experience with the 285k is really poor.

btw, I’m an overclocking expert, and I’ve tried all possible methods, including increasing iGPU voltage and memory voltage, to resolve this issue, but unfortunately, none of them helped.

Hello Strebor,

Good day!

Try the following suggestions:

• Follow the guide below to uninstall and reinstall HD Graphics driver. *Download the OEM graphics driver (Global) first.

1. Start Control Panel, click Hardware and Sound, and then click Device Manager.
2. Expand Display Adapter, right-click the Intel Graphics entry, and click Uninstall.
3. On the Confirm Device Removal dialog box, click Delete the driver software for this device to delete the Intel HD Graphics driver, then click OK to start the uninstall process.
4. When the uninstall process is complete, disconnect your computer from the internet and make sure it will not auto-connect on reboot. Restart your system.
5. Unzip the file (OEM driver file) to a designated location or folder.
6. Open Device Manager
7. Expand the Display adapters section.
8. Right-click the Intel® graphics entry and select Update Driver Software. Note: The graphics entry may be "Microsoft Basic Display Adapter". *Please check if the artifacts occur using the Microsoft Basic Adapter as well.
9. Click Browse my computer for driver software.
10. Click Browse and select the directory where the driver files are found.
11. Click Next. Drivers are now being installed.
12. Reboot your computer when prompted.

Alternatively, you can use Intel® Driver and Support Assistant to download and install the HD Graphics driver.

• Perform a system restore to a point when the artifacts were not present. Steps to perform a System Restore in Windows® 10:

1. In the Search option located in the start menu type Restore
2. Select Create a Restore Point from the search results.
3. Click System Restore.
4. Click Next after the initial Wizard screen.
5. Select either Recommended restore point or Choose a different restore point if you have manually made previous backups.
6. Select a restore point from the list of available options.
7. Click Next to finish.

i'm having the same issue, your instructions did not help at all.

I am experiencing the same issue (artifacts above 6600Mhz) as everyone above while using AstroPad's Luna Display USB-C adapter. I never experienced this issue with previous gen intel CPUs(12-13 series & Intel Xeon W Cpus). There is no over heating issues chip idols at 35c and reaches 85c on all core load. The thunderbolt usb-c connection need for operation is not over saturated and is operational. 

System Specs:

CPU: Intel core 9 285k (Intel Arc Graphic Driver 32.0.101.6458, Intel Graphic Software Version 24.50.1001.1 )

MOBO: MSI MPG Z890i TI WIFI (Bios: 7E33v1A4 - 2025.01.16)

RAM: 96GB (2x48GB) Corsair Vegeance DDR5 CL32 @ 6600MHz 

GFX: Nvidia Geforce 4090FE (Studio Drivers 566.36 - 2024.12.10)

OS:  Windows 11 Pro, Version 10.0.22631

I also see some minor but frequent artifacts with any of the three XMP configurations available on Kingston Fury CUDIMM RAM set when running any 3D content or GPU accelerated video on my 265K. The artifacts are immediately visible when launching affected media (i.e. not a heat issue) and only take place within such content bounds, not universally on the screen. Stress test applications indicate the system to be stable.

Hello,

I was experiencing the same issue with my 285k on an ASUS motherboard. Sporadic artifacts on the screen, especially when multiple windows were open in Windows.

I updated the Intel ME firmware from ASUS' website. The latest version as of 02-27-25 was 1854.

This seems to have fixed the problem for me. I can run a dozen YouTube videos simultaneously without any issues.

 I have not done a thorough tests using hardware test software but the IME firmware update seems to have fixed it in my case.

Best Regards,

Arabo
