This appears in my Dell XR12. I am using an Intel ACC100 (PDF download) acceleration card . But I dont understand the error. What is happening here? Any help is appreciated!

  • Please run latest Memtest86 version from a USB to see if it is RAM issue. Commented Sep 7, 2023 at 10:26
  • I have ran memtest and there are no issues with the memory! I assume its related to the PCIe slot and the ACC100 accelerator. But I am not sure how to debug this and get more information. Thanks for you help so far! Commented Sep 7, 2023 at 10:34
  • Since this is a server we can safely assume it contains ECC RAM, but to test this out you would need likely a Professional version which is able to test ECC RAM. Normal version - the free one - is not capable of this. Cheers and good luck. Commented Sep 7, 2023 at 10:36
