    I am using coreduotemp utility to check the temperature of my 2.4 Macbook Pro
    It gives 3 readings ttemperature cpu usage and cpu frequency The CPU frequency will read 1.5Ghz or 2.0Ghz. Is this a bug or what. Is there another utility that gives the clock speed.

    The processor probably powers down a bit when it's not being used a lot to save power.

    ive noticed the same thing with my 2.4 GHz SR MBP. even when it is plugged in and i am doing "demanding" tasks such as ripping a dvd, it will never go above 2.0 GHz, according to CoreDuoTemp. Anyone else know what the deal is?

    My MB always shows 2.17 Ghz and a temp of around 145 F.

    I'll tell you whats going on. FSB of old MBP is 667MHz. FSB of new MBPs is 800MHz. CoreDuoTemp is assuming the FSB is 667 and just looking at the multiplier. You lucky Santa Rosa MBP owners have to multiply your CPU speed readouts by 800MHz/667MHz or 1.2.

    So.....

    2.0GHz X 1.2 = 2.4GHz
