PC Processors

[radu1006]

Configuration:

- Ryzen 3700x with MSI b450 Gaming X plus motherboard and 3200MHz HyperX RAM

- Latest BIOS and latest AMD chipset drivers

- Ryzen Balanced Power Plan

- Default BIOS settings only the XMP profile 1 activated

Problem:

When moving the mouse on desktop, the CPU boosts to over 4GHz and the fan also spins up to compensate for the heat.

If I do not move the mouse, the CPU sits between 500 and 1000MHz, but if I start moving the mouse spikes to over 3-4 GHz.

I have tried to close all programs from system tray and killed unnecessary processes and scanned for viruses, but no luck.

Workaroud:

The only thing that worked was to edit the Maximum Processor State in power plan to 99%.

Also seems that moving the mouse causes about 6-7% extra CPU usage. It seems a bit much, but still a 8% CPU usage should not cause the CPU to boost.

The mouse is a Logitech G604 with Ghub installed.

You might have a USB controller issue.

Possible, but I could not find a way to debug that.

Here is a screenshot with no mouse movement and mouse movement spike.

Please note that I used the task manager only for screenshot purpose. Normally I only use one monitoring tool at a time.

The temperature spike in this case was quite big: 14 degrees C. The cooler is fine, since in full load, after 20 mins, the temperature does not exceed 66 degrees C.

Do it on your own risk. It worked for me.
