Cpufreq management is not obvious and not easy for a beginner.
However it is useful to save power and reduce the noise (lower speed of fans).
It is useful on laptops and also on desktops.
I use intel procs:
4CPU : i5-2500K CPU @ 3.30GHz (mageia 1)
2CPU : E7300 @ 2.66GHz (mageia 1 and cauldron)
On both machines, the lower frequency is 1.60GHz and I have set the governor
to ondemand.
In MCC-> services, cpufreq was enabled, but in fact was not working.
MCC has no tool to configure cpufreq
The plasmoid "Afficheur de charge système" (what is name?) shows the cpu
frequency when the cursor is above it.
IMO, ksysguard should also do that.
A question: Why is there cpufreq and cpufreqd?
There is also powernowd, which also controls cpufreq and which I haven't
figured out yet. It was written for AMD cpus, but apparently works with
Intel cpus, too.
