First of thanks for all the infos. I made a reddit post about my Setup and troubleshooting but i can put the info here also.
Computer Type: Desktop
GPU: GTX 2070 Super 8GB
CPU: RYZEN 9 5900X
Motherboard: ASUS X570-E Gaming
BIOS Version: 4021
RAM: 64GB Crucial Ballistix 3200mhz
PSU: BeQuiet 650W
Case: BeQuiet Dark Base 700
Operating System & Version: WINDOWS 11 PRO
GPU Drivers: GEFORCE GAME READY DRIVER - WHQL Driver Version: 497.29
Chipset Drivers: AMD X570 CHIPSET DRIVERS VERSION 3.10.22.706
Background Applications: Discrod, Steam, Little Big Mouse, OpenRGB, PowerToys, FiiO Driver, Stream Deck, HWinfo, Argus Monitor
Troubleshooting:
- Updating Chipset Drivers
- Replacing the Motherboard
- Extensive Stress Test under Linux for about 10 Hours without any issues. Leading me to believe it is a Windows related problem
- Updating my Bios to the latest Version.
- Turned of everything PBO related and now turned of Global C-State Control too
What i believe is happening:
Even though the behaviour stays after a reboot so making it look like a Hardware issue I believe it is a Windows Issue. I suspect something is causing the CPU to draw an excessive amount of power putting it in some kind of "Panic" mode and in trying to protect itself it clocks down drastically and limits the voltage to the CPU at 0.95V.If I go into Ryzen Master and apply the Creator preset raising the core voltage back up I can get my system to run at Base Clock without boosting. But the massive Power draw stays.Because my PC is connected to a Smart Socket I can also say that this jump in Watts is not "real". When this happens the Powerdraw of my system actually goes down a bit because he is only sending 0.95V to the CPU but still indicating an Power Draw of over 300Watts.'
Someone I have talked to on reddit with the same issues noticed that the only software we share is Argus Monitor. He turned it off Yesterday and apparently hasnt crashed since. You wrote that you also use Argus and now I seem to recall there was an Update not too long ago. And looking on their Website this is the changelog.
Not 100% sure but with the new Power Readings and the Asus Embedded Controller Support this "could" be the culprit in confusing the Hardware to go Haywire. Not sure just a guess. Maybe worth a shot turning it off and seeing what happens. I use it to control my GPU fans so I need to find another solution to do that.
