Windows is working fine.everything else you have said is way above my head.I have installed Ryzen naster and its saying cpu temp 30 degrees.screen has a purple colour instead of the normal ble.
Your idle temps are fine - would be interesting to see your load temps.
And you can change your colour scheme at anytime...
Yes - your CPU Frequency will be jumping too if you look at the same time.with cpu z the core voltage is jumping from 0,972 to 1.332 is that ok .
It's a power saving feature - the CPU downclocks when idle, as does the voltage.
