Memory Overclock question - FSB or FSB*Mult?

[TeMpT]

When people are overclocking and pushing their limits on the memory (reason to get good memory), is the FSB the limiting factor for the memory? Or is it FSB*Multi?

I thought the more I crank on the FSB, the harder my memory works. So my MEMORY is working harder if I set FSB=145 and Multi=8 (1160mhz) then FSB=133 and Mult=9 (1197mhz)

Is that right?

True. I think around 140 Mhz is a sweet spot since it gives a little boost without causing problems.

the multiplier adjustment on effect the actions inside the CPU, the FSB setting affects memory and other circuits outside of the CPU. The advantage of the overclocking the FSB is that you get better processing thru the memory. In theory, the CPU performance of a 1.0 Gig Tbird running at default (10.0 x 100) is the same as a taking the CPU and lowering the multipler to 7.5 and running the FSB at 133 (7.5 * 133 = 1.0 gig). The advantage here is that with the FSB speed at 133, you get significantly better memory performance yielding a better performing system even though the CPU speeds are the same.
