underclocking - Can't change CPU multiplier on board. Advice!

    Hello all,

    I'm trying to underclock (Duron 1.4, Syntax V266a motherboard).

    Now the issue is, this extremely featureless budget, but otherwise well
    performing, board won't let me drop the CPU multiplier below 133 (range
    being between 133-165).

    If I go ahead with the pencil trick on the cpu anyway will the board
    somehow detect this and allow me to drop the multiplier further or will I
    be still be stuck with the same multiplier range due to the the
    featureless nature of the mobo?

    Or indeed is there another trick to allow me to drop the multiplier?

    Oops, clearly its the FSB that won't drop in the bios. There is no
    multiplier setting in the bios as far as I can see. Either way and
    anyway, I'd like to drop both the multiplier and the FSB.

    Usually, There's a jumper setting on the MB to set the default FSB to 100
    or 133. You really don't want to go in between these settings unless you
    really know what you are doing because of the way it affects the other
    bus speeds. Check your MB manual for FSB jumpers. Some boards also have
    jumpers for the multiplier, or to enable the bios to change them. Of
    course the ability to change the multiplier will depend on if the cpu you
    have is locked or not. And that's another can of worms. More info in
