Hello everyone,

I've been seeing bsods and freezes on my pc for a 2-3 weeks now, I could look in the event observer and I have "Cache Hierarchy Error" , this week I had 11 "kernel power" bsods ...
I had noticed a difference of +10°C between ccx1 and 2 without worrying too much because temperatures do not exceed 80°C max on ccx1 and 70-68°C on ccx2.

But now I have random bsods which prevents me from using my machine without stress.

I updated my uefi with the latest agesa 1.2.0.1 (without pbo, all stock), I have the latest chipset driver, and the latest update of windows 10 (clean installation).

My setup:
-AMD Ryzen 9 5900X
-Noctua NH-D15 chromax black
-MSI Tomahawk B550
-AMD 6800XT
-Crucial Ballistix RGB Rev-B 2x16GB 3200MHz CL16 @ 1.35V (stock)

-Bequiet Pure Base 500DX
-Bequiet STRAIGHT POWER E9 | 680W

-WD BLACK SN750 NVMe - 1Tb | OS

Thx for your help ! 

Edit:

Karhu memtest (6 hours) + memtest 86 (12h+): ok

OCCT + SSE: ok

I have seen the threads, I have seen the tricks to increase the tension, I have tried without success and I don't find it normal to have a cpu that needs more tension suddenly without any change ... 

thanks
