Well after messing with cpu/memory fsb's, memory latencies, and multiplier on my Athalon XP, I got it about as quick as I could with gimps. I tryed raising the memory FSB to 333mhz, but I was unable to use lower memory latencies (unstable). I finaly settled with the following configuration.
AthalonXP 1800 (clocked at 1725 mhz, multiplier of 11.5, CPU FSB of 150 , DDR Ram FSB at 300mhz and all memory latency's set as low as possible) is pulling a Per iteration ime of 0.059 sec
The same configuration above using default latencies yielded a Per iteration time of 0.072 sec
I tryed various multipliers and cpu FSB's to get my memory stable with the lowest possible latencies. It appears, tweaking the memory yields much better results than the actual overclocking of the CPU. Just a thought that may help others. Share your results!
