UPDATE - Prim95 error at 3:13 hour mark - (I never ran this test more than 1.5 hours, this time I forgot to turn it off and found an error after a nap). This error was created with BIOS overclock set to OFF vs AUTO, so CPU never exceeded 3.68GHz and ((usually boost up to 4.6GHz when BIOS set to AUTO)) ADATA 3600 RAM XMP was not used and set to AUTO, and speed manually set to 3600). Is this proof of my CPU being the problem or?
FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected running 2400K FFT
========================
My build randomly loses power during gaming. - I have replaced EVERY device listed below except for the CPU. - no over clocking but when I let RYZEN auto overclock my system was more stable and crashed less. Furmark, Prime95 and OCCT, Benchmarks like Valley and Heaven left to run over night several times have never crashed my system. Programs listed above do not crash my system. I have tried 3 mothers board, Asrock B550M Pro (two of them) and my current Asrock B550 TaiChi, system specs below.
- Age of Empires 4 will crash my stock setup after 1-10 minutes of gaming,
- Creeper World 4 will crash my system after 10 - 60 minutes.
- Youtube video will crash my system - VERY rarely
NO BSOD - only sudden power loss.
- Event View only shows me:
