    According to this it says that my clock speed is 998.7 Mhz. My processor is the Core Duo 1.83.

    Does this make sense? Please explain.

    Thanks

    That is the speed of one core, VCman. If you take a look at the bottom right of that window, you would see that there are 2 cores. Users with single core CPU's would see the no. 1 next to it.

    998.7 MHz x 2 ~= 1.83 GHz

    Wait.. NO.. That's not right at all!

    Both cores can run at 1.83ghz!! It is running at that speed to conserve battery life and or/ your power settings are changed to maximum power etc. It will only run at the speed it needs to run at.

    Yeah, the cpu is running at ~1GHz due to Speedstep. It will dynamically increase as and when needed. Dont worry about it, it is quite normal.

    Yes the FSB is a constant 166MHz

    And Intel SpeedStep allows the CPU Multiplier to vary from 6x(1GHz) - 11x(1.83GHz) to save on battery when the computer is idle or just doing easy tasks.

    oh ok thats a relief. Is there any way to change this speed to your desire? Like keeping it on full 24/7 or even lowering it more?

    Change your Power scheme to Always On. This will set the processor to run at full speed 24/7. But I wouldnt recommend it since the performance will be the same except it will run hotter and you will get less battery life.

    If you want more options to control Speedstep, then try RM Clock or NHC. Both allow you to set custom multipliers(6 - 11 only) and voltages. The processor speed can only be reduced further by down clocking the FSB. The multipliers are locked blow 6x and above 11x.

    Go to Control Panel, then Power Options and select Home/Office Desk as your power scheme and this will force it to run at full speed when on AC and underclocked (SpeedStep) on battery.

    More information can be found in the following thread:

    it will jump to full speed whenever processor load is high enough.
