    I would like now to share my big secret with you.

    Most of the time I do not stress my CPU, since I write Internet posts and documents.
    So, I do not want to be overclocked all the time.
    I like my CPU to be COOL n' QUIET.

    This is how I did it to cool down my system been OCed at the same time.

    I found my stable OC settings using the limits technique combined with my program I mentioned before.
    You may find your OC settings any way you want though.
    The only restriction is that you need to use the default CPU multiplier.
    A stable setting in my case is at 2800MHz.
    I decided to oc just a bit less. 2700 is great for me.
    Though at this OC my CPU needs 1.50v and generates a lot of heat.

    The default CPU multiplier for 4400+ is X11.
    So to get 2706 MHz I need an FSB of 246MHz (246X11=2706 MHz).
    In BIOS I used: manual overclocking, FSB=245, K8 to NB = x4 (245x4=980 which is a bit under 1000)
    The other HT was set at 200X5=1000.
    Finally I enabled CPU overvolting and set the proper memory timings for FSB=246 at 1T 1:1 (200MHz limit).
    (Depending on your dimms you may use 2T and / or a divider like the 166MHz limit).

    Next, I entered Windows, removed AiBooster and installed AMD CPU driver and the WindowsXP-KB896256-v3-x86-ENU.exe update.
    I made two .reg files.

    One to dissable throttle
    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Throttle]
    "PerfEnablePackageIdle"=dword:00000000
    And one to enable throttle.
    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Throttle]
    "PerfEnablePackageIdle"=dword:00000001
    Then, I enabled throttle (copy - paste the quoted text on a .txt file, rename it to throttle.reg and double click it)
    and chose the "Minimal Power Managment" power scheme (control panel - power options - Power schemes).

    And the trick is ...

    I ENABLED COOL n' Quiet in BIOS

    Now my CPU works at 246x5=1230MHz, 1.25v, 32oC.
    When I run a program that needs more power the CPU multiplier changes instantly to x6, x7, ... or x11, to give the needed power and the same is true for the vcore.
    So when I play games like HL2 I get all the power I need at 246x11=2706MHz.
    Check this validated CPUz at 245x5.

    Try this trick and give us your feedback. Enjoy...
