i was just thinking, when you're ocing your fsb and say you change you ram ratio to 5:4 to get a higher fsb, your effective oc would only be 4/5 of the set fsb, right? because the cpu could only talk to the ram at 4/5 of the fsb:confused:
 
If you're on an AMD platform, the ratio should ALWAYS be 1:1 (6:6 is what most people like). But, if you're on an Intel and you change the ratio to 5:4 then your RAM will be doing FSB x 5 / 4 and your CPU will be doing FSB x 4 / 5. Something like that. This function is utilized to maximize memory bandwidth and get a precision overclock for the CPU's FSB. Never a good idea on an AMD platform. Pretty standard on Intel.
 
but (im prob wrong) the memory bandwidth being higher than cpu's is a waste, because the cpu could only retrieve information at it's fsb, or vise versa.
