different numbers. how can I know when is too much for the mbo
(if it is not too much for proccesor). i hope you understood the question

Welcome to the forums.

You'd normally see Intel CPU's/Mobo's running fsb's between 1066-1800'ish or even higher. Depending on the oc-ability fo your chip. First sign that its too much is your system becomes unstable.
