if you have ram that is resistant to heat and high
frequency and stable it's a good thing.
And yes there is one thing about overclocking with the
FSB and overclock the multiplier is different. if you
want a high-frequency have to loosen the timming,
because the increase in FSB will trigger an increase
in frequency of ram. and a lot of ram that can not
stand the high frequencies, in addition to requiring
by adding voltage also gets hotter. and usually
in benchmark score oc FSB againts multiplier
result is higher oc FSB.
