does a mobo fsb have to match the CPU fsb?
No, the FSB of the mobo does not have to match the CPU of the motherboard, and vice versa, but if they don't match, then you are losing out on performance since either the motherboard or the cpu will have to clock down to match the lower fsb. Therefore it is always best to get a motherboard and cpu with nearly the same fsb, but if they don't exactly match it won't cause any major problems.
how do you find out the fsb? i tried everest. they have a lot of specs but nothing definite for the fsb of either the mobo or the cpu. is there some formula needed to figure these numbers out?
Everest won't give you the fsb of your motherboard or cpu, but it will give you the motherboard model number and the type of cpu you are using so that you can then google for each and find the technical specifications for each of them and then you will be able to find out the fsb of each.
