Mb: Asrock B450M pro 4 latest bios 3.90 (tried with all other bios)
Power plan: Balanced, high performance, ryzen balanced, ryzen high performance... same problem
Latest chipset drivers
In Windows Power Plan, what is the Minimum & Maximum Processor State at? Minimum should be at 5%. Also see if you have Cool N Quiet enabled in BIOS.
I would check to make sure you have the latest BIOS/UEFI version installed.
jofil, please post a screenshot of Ryzen Master (RM) - simply drag-n-drop the image into your reply. Open Settings-Apps and uninstall any junk you can find. Run only RM and not HWinfo or any other monitor applications. Remember, the processor only does what the OS tells it to do - something is running. Thanks and enjoy, John.
I have the exact same issue! When I boot, ryzen master reports PPT at 100% and the CPU temp rapidly rise. Until I open windows task manager, and the PPT drops to a normal level (30-40%). Once task manager has been opened once, it can be closed and the system behaves normally.
