I can reliably trigger a BugCheck 0x124 WHEA_UNCORRECTABLE_ERROR

I would get this BSOD occasionally when using my computer, sometimes once a month, sometimes multiple times a week.

Until recently this was very unpredictable. I can play games for hours without any problems, and then something as simple as opening edge triggers the BSOD.


I can't really nail down what the problem is.


The system in question is OEM. Nothing has been changed.

Model: Acer Predator PO9-900.

The system is not overclocked, and the BIOS settings are on default.



Some things that I tried:

  • Performing memory diagnostics using the Windows tool and Memtest86: Tests pass, did not cause problems
  • Updating drivers and BIOS: Would not solve the problem
  • Removing SLI GPU bridge: Would not solve the problem
  • Remove either one of the graphic cards: Would not solve the problem
  • Running the Intel CPU test (Intel IDT utility): Test pass, did not trigger BSOD
  • Running Prime95 stress test: Did not trigger BSOD
  • Running Furmark stress test: Did not trigger BSOD
  • Running SheepIt render farm client: Seems to agitate the problem but sometimes runs for a day before the problem happens.

The temperature never seems to rise above 65-70°C when doing tests.


By sheer accident, I found a reliable way of creating this exact BSOD.

In my case I run FFmpeg with this set of parameters:


FFMPEG.EXE -i "input.mp4" -c:v libvpx-vp9 -crf 12 -b:v 1000k -an "output.webm"


This will with almost 100% certainty trigger the BSOD within the first two seconds. As far as I know, ffmpeg does not utilize GPU features to convert files, so I'm pretty sure the issue is not related to the graphics cards.


A few Minidump files from this error: https://cable.ayra.ch/temp/dumps.zip

Quick edit: The problem can't be reproduced when ffmpeg is running inside of a virtual machine.
