I am also able to consistently reproduce the crashes with OCCT 3D test and Power test, both of which are GPU heavy tests. After 5 minutes of either of these stress, either of these cashes happen:
Here are some of the things I looked into:
Specs and stress test screenshots (OCCT )
- video + audio freeze, need to restart manually
- system shuts off and on again, then fails before even posting and goes into a reboot loop. Need to turn off power manually and wait for the system to cool down before being able to boot.
Here are some of the things I looked into:
- No apparent overheating: GPU and CPU at max 75°C under load.
- Memtest OK
- Didn't find relevant events in event viewer (except manual reboot)
- Increased Virtual Memory to 1.5x RAM amount with no effect
