Does you cpu support a technique like speed stepping? Then try setting
the scaling governor to ondemand
% modprobe acpi_cpufreq
% echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
This may be working betten than using coufreqd?
Or maybe you could lower the cpu and ram voltage in bios? But this can
cause an unstable system.
