Maximum Speed should perhaps be relabelled Base Speed

For my CPU, AMD Ryzen 5800X, it is the Base Speed which is 3.80 GHz, not the Maximum Speed.

Hi Tim,
In Linux, maximum speed can be set to other values(writing value of allowed max speed in cpu config) depending on power profile. In battery saver, balance, and performance profile one of the parameters that are changed is the max clock config parameter.

Can you do a strees test on one core and find the the max clock?

commented

Thanks,
Can you let me know your system details?
I will see where is there problem and fix it soon.

I have Ubuntu 21.04 with the standard kernel.

Can you check which version of python and psutil you r using?

psutil is wrong

import psutil
psutil.cpu_freq()
scpufreq(current=3887.256625, min=2200.0, max=3800.0)

commented

I suppose you could work around by reporting as Max the highest frequency seen.
Under load:

psutil.cpu_freq()
scpufreq(current=4501.059875, min=2200.0, max=3800.0)

I reported to psutil giampaolo/psutil#1973 (comment)

Thanks will look into it.
