Is this [CPU info] normal ?

    hello,
    I used Everest Ultimate to view my detailed specifications and i found this about my CPU speed :

    CPU Clock 2005.0 MHz (original: 3000 MHz)
    CPU Multiplier 6x
    CPU FSB 334.2 MHz (original: 333 MHz)
    Memory Bus 401.0 MHz
    DRAM:FSB Ratio 12:10

    is this normal (the CPU clock) ?

    all my specs are listed.. and i'll add any other details you might request.

    thanks.

    Welcome to WindowsBBS :)
    Although I have only recently moved over to Intel for my latest build I think that is perfectly normal given that Intel use speed stepping technology as indeed AMD do with their Cool'nQuiet.

    Basically the CPU runs at a speed appropriate to the demands placed on it by the system - in other words it does not run flat out all the time. This reduces power consumption and heat generation.

    I would not be certain it's normal. I don't have a problem with the FSB but the CPU should not be running at 2/3 speed. Unfortunately, you did not provide us any information about your CPU or the computer and Pete is correct, SOME CPUs, notably those destined for mobile (running on batteries) applications can toggle down to conserve power and/or reduce heat, and SOME CPUs for PCs can too. But most CPUs in use today that were designed for PCs, don't toggle down when idle, or at other less demanding times. The clock still ticks away, even if the cycles are not used.

    This is what Everest reports for this PC:

    CPU Clock: 3071.91 MHz (original: 3066 MHz)
    CPU Multiplier: 23.0x
    CPU FSB: 133.56 MHz (original: 133 MHz)
    Memory Bus: 534.25 MHz​

    What does CPUz say?

    For my new build CPU-z gives 1600 Mhz 'idle' which peaks to 2800 MHz underload - Open Photoshop x64 or open largish image file.

    Everest Ultimate gives the readout attached.

    My AMD processors behaved similarly when running Cool'nQuiet.

    It will be interesting to see if this is a new build too, or not. Thanks Pete.

    A follow up on this - in Windows 7 the choice of Power Option has a bearing on CPU speed ....

    Balanced - the default, appears to control the CPU speed as noted in my earlier post - that's the setting which I was using.

    Poking around this morning I selected the Performance option - CPU runs flat out all the time with this setting.

    Bill - throttling down has been on Desktops for awhile. :)

    Intel introduces new functions

    Of course the Bios has to support it "“ and have it enabled.

    Right. I should have been more clear that the CPU and motherboard/chipset must work together.

    Guess I wasn't clear. Since 2005 most CPU's DO toggle down. Most bios's since then support it and it's enabled by default. All Intel chips starting with some P4's have the features incorporated in them, including the Core 2 Duo’s, Quads and I7 families.

    That’s why the 1st posters results were probably normal. An Intel E8400 would give identical results under a light load. The multiplier has been toggled from a max of 9 (with that bus) to 6. Along with that there’d be a core voltage adjustment to maintain stability.

    Result being less power consumption, less heat and more importantly for most – considerably less noise as the cpu fan would then slow down.
