Question Kernel-Power Critical Failure on Stress Test

Aug 30, 2019
TL;DR: Kernel-Power Critical Failure using XMP. No failure with XMP disabled.


I have recently built my first PC and I've been encountering a black screen and a reboot. I've checked Event Viewer and saw a Event 41 Kernel Power Critical Failure. This does not occur during daily use but occurs during a Cinebench R20 Benchmark, CPU-Z stress test and when I stress my CPU. I have not overclocked or enabled any additional features or options outside of XMP.


Here are my PC Specs:
  • CPU: Ryzen 9 3900X
  • Motherboard: Gigabyte X570 Aorus Xtreme
  • RAM: Crucial Ballistix Elite 3600 CL 16 (2 x 8Gb)
  • CPU Cooler: Wraith Prism (Stock cooler)
  • PSU: Cooler Master V1000 80+ Gold (Replaced once)
  • GPU: Nvidia GeForce GT 705 (Pulled this out of a old Dell somewhere, still waiting for my graphics card to arrive)
  • OS: WIndows 10 Pro Latest Build

Here's what I've tried:
  • I have updated all drivers and BIOS to the latest version.
  • Replaced my PSU (Replaced Cooler Master V1000 with another V1000)
  • Updating and trying both main and backup BIOS.
  • Tested both ram sticks individually in all 4 RAM slots, failure persists.
  • Test both ram sticks in A1, B1 configuration and A2, B2 configuration, failure persists.
  • Tried using WhoCrashed. Unfortunately, Windows does not create any dump file and thus WhoCrashed does not work.

Additional information:
  • I have plugged in both 8-pin CPU power.
  • Bios version: Gigabyte F3
  • Benchmarks and stress test FAIL using XMP 3600 CL16 (1800 Infinity Fabric) but PASS using 2666 (1333 Infinity Fabric)
  • CPU temperatures do not exceed 82C.
  • CPU throttles at 80C.
  • CPU and BIOS settings are stock with only XMP enabled.
  • PC built on August 28 2019
  • Black screen occurs, PC reboots. There is no BSOD.
