Linux reports my CPU's maximum frequency as 2.40 GHz and min as 1.2 GHz. Windows 8's Task Manager shows the CPU frequency going above 3.0 GHz or below 1.0 GHz on occasion, according to usage. This is something I have noticed in 12.10, 13.04, and 13.10, as well as Arch Linux.
I have a 3rd-gen Corei7-3630QM CPU @2.40 GHz, according to
lshw -c cpu.
Anybody know how Windows gets to the larger range of frequencies?
What will happen if I force set the maximum and minimums to more extreme values, by doing something like:
for file in /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq do echo 3001000 > $file done
Right now the exact maximum frequency in all /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq files is 2401000.
