how do 
while overclocking the last time round i have set my MCH and FSB overclocks to +0.2 - just cuz people have said its worth doing...
but what exactly is this doing? where is the extra voltage going to and as a result is better cooling required at those points? i only ask cuz .2 is quite a lot, if you added that to the vcore you'd fry the cpu...
also, is it both that require a boost or just one of em?
