I always thought to get hi memory bandwidth for my th7ll it was necessary to torture my pc1066 at the highest speed possible.What i normally did was to run my 1.6a @150fsb x 4 on my memory timings. That effectively gave me a 2.4 processor speed, a 600 mhz fsb and rdram running @ pc1200. this setup gave me a sandra bm of around 36-3700. fortunately i have a real nice cpu that really cranks and this allows me to experiment with all kinds of different fsb settings and memory multipliers.on a lark the other day, i decided to crank up the fsb to 170, bump the memory multiplier to 3x and do some benchmarks. to my amazement with only a 20 mhz increase in the fsb and runnin my rdram at a modest pc1020 (a 180 mhz drop from my original setup) i got benchmarks of around 3500. i have come to the conclusion i was not comming anywhere near near using the available bandwidth of my rdram when i was running it @ pc 1200, and it is more important to saturate the fsb in order to get a more efficient thruput. this allows one to come much closer to the theroetical banwidth of the rdram at any given speed . the only drawback is that the cpu used has to be a good overclocker and allow hi fsb settings. lastly, i bet this holds true for ddr also...... flapperhead
