Depends on the motherboard. Some will not recognize it and will not boot up
at all.

Dear Motherboard Gurus.... tell me if ...

... it would do any harm to plug in a CPU of a higher FSB rating than
the MOBO is designed for ?
My mobo has a fsb rating of 400MHz but my P4s rating is 800Mhz.
I personally feel it woud do no (physical) harm except, perhaps,
to 'pull down' the P4's capability and cause it to be under-utilised?
Please correct me if I'm wrong
thnx
