well, "ondemand" scales the frequency up and down depending on the needs at the time... when you posted this you were set to 797.814 MHz so i would assume it was a point in time when you weren't really doing anything processor intensive... starting something like a huge virus scan or a big compile would be expected to boost your CPU's power as needed...
in any case, i find the "ondemand" behavior great for when running on AC, but when on battery i prefer "powersave", which keeps the CPU frecuency low no-matter what the cpu load is... the lack of "high" spikes saves battery power and keeps things running cooler...
to put your CPU into "powersave" mode do a:
Code:
sudo echo "powersave" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
to put it back into "ondemand" just change the approriate part of the command...
