there is the possibility that setting yours to 2.5 and 6 that your loosing the 200 or so marks in the score, but remember that sandra is only a synthetic benchmark and in real world performance you probably won't notice a diffrence at all between 2.5,6 and 2,5 I'd think that the most influental setting on my sys that's giving me the biggest boost is the 1T Command timing setting. good choice about going for as much fsb as you can, the more bandwidth you can give your system the faster it'll be, I'm gonna try for a fsb of 190 soon with the multi at 9.0 wich will give me the same speed that I'm at now but running 190fsb, but I don't know if I wanna put my hd's that far outta spec
