9800x3d Windows Task Manager Reporting Error

[CuriousSloth]

Hi, I've been having an issue lately with windows task manager intermittently reporting erroneous CPU clock speeds. It only occurs when the processor is at low load and I can't figure out why it is happening.

I have had PBO enabled in the motherboard and I've been playing around with some built-in modes as well as using the advanced mode to undervolt (pushing the core clock by 200MHz, and upping the PBO scalar to 10x). Suspecting this is happening because the telemetry circuits are not receiving enough voltage due to the applied undervolts, I have now disabled PBO completely in the BIOS; however, the error persists. When under any sort of load though (greater than around 10%), this never occurs. I have googled around and I can't find any mention of this anywhere.

I have attached a screen capture of this happening.

I would be grateful for any insight anyone has on what could be causing this or how to fix it.

Thanks

 

Specs

CPU: Ryzen 7 9800x3d

RAM: x2 16GB Corsair Vengeance 6000MHz (EXPO enabled in MOBO)

Motherboard: MSI B650 Gaming Plus Wifi

 

 

Edit: I have checked on HWinfo64 and it is showing stable clocks, but the core utility is spiking to millions of percentage

 

 

Edit 2: I have booted into my arch linux drive and I am not seeing anything resembling this behaviour in htop or btop - maybe its just a windows issue?

What power scheme are you using in Windows?

High performance or Balanced or something else?

I have been using AMD Ryzen Balanced, but I tested with AMD Ryzen High Performance to no avail

 

Edit: I have reinstalled windows and the issue seems to have disappeared. I assume this may have narrowed the issue down to ryzen power plans. I will do some testing

 

Edit 2: Solution - ryzen power plans deprecated for newer ryzen processors, I read it's recommended to use windows default power plans since the newest chipset drivers are designed to work with them
