After reading all the debate about latencies vs. FSB, I decided to experiment. On my machine (see sig), I found that increasing latencies from 2-2-2-5 to 3-3-3-7 caused only a 1.7% decrease in memory bandwidth at the same FSB (200). However, increasing the latencies allowed me to go from 200 to 240 FSB, which yielded a 20% increase in memory bandwidth (with the CPU multiplier backed off to keep it at a comparable speed). I have bitmaps of the benchies if anyone wants to see them. I don't know how to post them.
So I guess the conclusion is, if you can gain at least a 2% increase in FSB by backing off your latencies a notch, then it's worth it.
Sorry if this is a "DUH!" to the old hats, but as a relative noob I thought it was interesting.
