[gentoo-user] cpufreqd and Pentium 4

[Daniel da Veiga]

Hello list,

I followed the Gentoo Power Management Guide on:
http://www.gentoo.org/doc/en/power-management-guide.xml

And installed cpufreqd, edited the config file and tested some
configurations. I noticed it changes the frequencies all the time. Is
there any side-effects on my CPU for this frequency changes? Will it
reduce the CPU lifetime or anything like it? I couldn't find anything
on Intel or Google to see if its harmless or not to use this feature.

Thanks for any comments,

It is almost certainly a net benefit to use power management.  By
reducing the clock rate and turning off parts of  the processor not in
use, you reduce the power consumed by the CPU and thus the heat
generated.  Heat is your biggest enemy for CPU longevity, so reducing
that is always a good thing.
