    Hi all,
    I have just used CPU Speed Pro to test my processor clock speed and it has turned up some strange results.

    My laptop is a MSI GT725 which basically has a quad core Q9000 which should be clocked at 2.00Ghz per core.
    It also has a Turbo button which ups the frequency by various %ages based on the BIOS settings.
    Mine is set to the max of 24% boost.

    If I run the CPU Speed Pro test with the Turbo on and it clocks at 2074Mhz, bit low but not that strange.

    However, if I test with the Turbo off it clocks in at 874Mhz. ???

    Does anyone have experience with this utility and is this reading indicating a problem with my CPU or a quirk of the program ?

    Any advice gratefully received.

    Since it's a laptop, it's probably throttling speed to save power, control heat, etc.

    Thanks doublehelix, the figure would make sense if it was throttling as I would expect in a low power state the CPU to clock at 800Mhz.

    I just thought when the program puts a 100% load through, the CPU would come out of any throttling phase.

    It should. Whether it does or not for the program you're using is in question. I wouldn't believe the app over the specs unless you bought it from a less than reputable place.

    Ok, CPUZ shows the same 2074Mhz under Turbo mode, with Turbo turned off I now clock at 1595Mhz.

    This is still down on the expected clock speeds of 2Ghz and 2.4Ghz ?

    What is in the Specification field? You're looking at activity.

    The Specification tab lists the quad core Q9000 @2.00Ghz

    There's your answer. You have the processor you expected.

    would you not expect it to show up as 2000Mhz in the Clocks section ?

    No, I wouldn't. Your computer will use the clock speed and power it needs when it needs it. It would be a huge waste of power and longevity for a processor to run full-out at max speed when the system is idling.
