Hello,

Has anyone tried changing the voltage for their CPU using either cpufreq or cpufreqd? Google does not seem to want to be my friend on this one.

it seems no popular desktop CPUs support dynamics volatage adjustment yet

I dont necessarily mean scaling the voltage dynamically.

There's a nifty program I use on Win XP called Centrino Hardware Control. Aside from letting me switch power profiles, it also lets me set the voltages for the different multipliers of my Pentium M. I use voltages lower than the stock voltage settings and as a result I get lower temperatures and more battery life. I was just wondering if there's something in Linux that can do the same (i.e. something that lets me change the stock voltage for the different CPU frequencies).
