CPU: Ryzen 5 2600x
MOBO: ASRock X370 Fatal1ty ITX
BIOS: started with 6.0, downgraded all the way down to 5.60 and now upgraded all the way to 7.40
OS: Windows 11 Pro
The symptom is the CPU will down clock/throttle itself down to 0.54ghz on every cold boot. When I restart the PC it will function as normal at 3 GHz. I have tried to overclock at 3.8ghz.1.31v just to see if that changes anything, it did not. I have tried to clear cmos and load optimized defaults - that changed nothing. I have tried to reinstall Windows a few times. Same result.
I have tired the x370 chip set drivers from the ASRock website, and I have also tried the latest ones directly from AMD. Currently the ones installed are v6.05
I have read online to install Ryzen Master utility and disable procot (or something like that) and I have done this and it does work. But this seems like more of a band-aid type fix that I am not comfortable with. I would much rather learn what the actual issue is and try to resolve it.
I have reseated ram and CPU and repasted also with artic silver compound. I'm using a tower styled heatsink cooler and the CPU temperature according to the bios, speccy, and cpuid hwmonitor, all report less that 40c. When I use CPU-Z to stress test the CPU I see the temp go up to 60c but never higher.
I'm leaning towards a defective motherboard but I would like to actually rule that out of possible before I just replace it. It's an smaller itx board and a replacement is costly.
