</I>&gt;<i> However it is useful to save power and reduce the noise (lower speed of fans).
</I>&gt;<i> It is useful on laptops and also on desktops.
</I>&gt;<i> I use intel procs:

</I>&gt;<i> 2CPU :  E7300 @ 2.66GHz (mageia 1 and cauldron)
</I>&gt;<i> On both machines, the lower frequency is 1.60GHz and I have set the governor

</I>&gt;<i>
</I>&gt;<i> In MCC-&gt;  services, cpufreq was enabled, but in fact was not working.
</I>&gt;<i>
</I>&gt;<i> MCC has no tool to configure cpufreq
</I>&gt;<i>
</I>&gt;<i> The plasmoid &quot;Afficheur de charge syst&#232;me&quot; (what is name?) shows the cpu
</I>&gt;<i> frequency when the cursor is above it.
</I>&gt;<i> IMO, ksysguard should also do that.
</I>&gt;<i>
</I>&gt;<i> A question:  Why is there cpufreq and cpufreqd?
</I>&gt;<i>
</I>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.
