    when all my cores in windows are at 2.1Ghz and intel turbo boosts puts then at about 3Ghz when tasking them i tried using

    echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

    to fix it becaus ei saw a few threads that did the trick but when i run it even as sudo it tells me i dont have the proper permissions for it

    Re: cpu clock speeds on asus g74s wrong in ubuntu 12.04

    most likely intel speedstep power saving. (you can turn this off in BIOS but I'd leave it on)

    try run some CPU intensive tasks and check speeds again.
