you should be able to push that to 2,5ghz by using 228mhz as fsb leave htt set at 5x
also make sure you set mem timmings, you should be able to leave mem set at 200 basically 1:1 ratio. will depend on what memory you run
i can have mines run at 250mhz if i take out the 2x 512 dimms and just have 2 gig but i like the 3 gig and haveing it run at 215
you will need to bump the cpu volts by .60mv works ok on mine's
