    Hi All .....

    .... would it do any harm to plug in a CPU of a higher FSB rating than
    the MOBO is designed for ?
    My Intel mobo ( D845GLLY) has a fsb rating of 400MHz but my Intel
    P4s (2.4GB) rating is 533Mhz.
    I personally feel it woud do no (physical) harm except, perhaps, to
    'pull down' (underclock?) the P4's capability and cause it to be
    under-utilised ( and, perhaps, even run cooler? )
    The D845GLLY Intel Mobo manual states -

    "Supports the Intel® Pentium® 4 and Celeron® processors with 400-MHz
    system bus in the mPGA478-pin package to the mPGA478-pin package."

    Your advise / feedback is appreciated.

    I asked a similar question a while ago (800fsb CPU into 533 mobo) and the
    response was it should be ok except of course the CPU will run at half its
    rated speed. Otherwise depends how brave you are!

    The CPU was unharmed though.
