Cpu clock is always boost

Support

In any case, the cpu is stuck at boost clock. It never goes to base clock. shows these values ​​at rest. It was also observed in earlier manjaro versions.

Manjaro: 24.0.1 (kernel 6.9.2-1)

Info is probably inaccurate, check:

watch -n1 'cat /proc/cpuinfo | grep "cpu MHz\|processor"'

and

grep -R "." /sys/devices/system/cpu/cpu0/cpufreq/

Share it also here. Thanks.

It could be an interesting option to install auto-cpufreq from AUR.

You can look into amd_pstate.

Here is the output. Not all of them have a core boost (4 of 12).

The cpu scaling governor is set on performance. That might be the issue :thinking: I don’t wonder that it won’t scale down.

sudo cpupower frequency-set --governor powersave

Usually powersave should be the default. Did you change that?

Thanks. (I didn’t set it up.)
