Lower Multiplier - Higher FSB?

I think I read somewhere that you want to have the FSB as high as possible, and one way to achieve this was to lower the multiplier and raise the FSB so that you have the same clock speed. Is this true? If it is, do I have to do it in small increments like you would when you normally OC, or should I just jump to the maximum FSB I can get whilst keeping the same clock speed?
 
Well yes and no, the general concensus is the higher the FSB the better but there is only so high you can go and you have to tweak it to get maximum settings from it and work out what is best for you.

Never do massive jumps in anything in the BIOS, always little by little to find its true limit
 
Can I ask what processor, motherboard and RAM you have.
Pre-SandyBridge it was mostly FSB but that was dependant on your RAM being fast enough because it runs faster as the FSB rus faster. With SandyBridge you should leave the FSB at 100 and change the multiplier and just set the RAM speed.

I have AMD Athlon II X2 250 on a Biostar A780L3L 760G with 4GB Corsair DDR3 1333MHz. Not much, but good for what I use it for.
