CPU speed related to Ram Timing?

Archived from groups: alt.comp.hardware.overclocking (More info?)

I have a Northwoods 2.8 and Kingston Hyperx DDR 466. Do I understand that I
can push the timings of the ram lower, and also cause of DDR 466, push the
CPU higher? I had some Corsair value Select stuff (DDR 400) that I couldn't
improve the timings at all, and the CPU would not go past 2.9, but so far
with this KIngston DDR 466 I have the ram voltage higher and timings of
3-3-4-7, the cpu @3.2....would DDR 400, but with faster timings give this
boost in speed?

TIA
