Pls help with error code : Primary Surface - D0809

The Primary Surface Test verifies the currently displayed portion of video memory (also known as the frame buffer) is free of defects.

A "D0809 video memory defect" typically refers to a specific error code indicating a problem with the video memory (VRAM) on a graphics card, often signifying a faulty memory chip or connection within the GPU, potentially causing visual glitches, artifacts, crashes, or even a complete lack of display. 

• This code indicates a failure to properly access or write data to the video memory due to a hardware issue.
• Potential causes:

  • Faulty memory chip: One or more of the VRAM chips on the graphics card could be physically damaged, leading to corrupted data.
  • Overheating: Excessive heat can stress the VRAM, causing instability and errors.

  probably good idea not to stress the cpu in this case especially in a SFF which has a weaker cooler

@redxps630​ Thank you for your reply. Maybe the stresstest itself caused the overheating. Is there a way to replace the internal GPU? Or should I just disable the internal gpu and use a external gpu?

when you are using a dGPU and not using Intel multi display then the integrated gpu is not outputing video.

you can not replace the integrated gpu without replacing the cpu

@redxps630​ Thx for all your effort. I am going to run the stresstest again. If the error reoccurs then I'll get a basic PCI Video Card.
