yeah, people have gotten over 200mhz fsb with lower settings, but it doesn't help their scores too much. you have to hit a really high fsb to make up for the low RAM timings, plus you have to up the voltage to 2.2v, which is way over the 1.75v default.
as for my setup, it's the standard 8k7a/crucial setup that everybody's using. the cpu tops off at 166mhz fsb at 8-8-6-2-2-2-2. to get any higher i'd have to lower the timings.
