ditto, ka7 here as well. my guess is that you gotta use a higher vio (or whatever its called, 3.5v and higher?) and maybe put a heatsink on the northbridge. ram could be a factor here too... but one thang i know fo sho is when you do clock the fsb up to 127 from 100 you see a near linear performance increase. this shows why p3e runnin at fsb is slower than athlon clock for clock; only p3e's runnin 133+ fsb outperform athlons which is no surprise.
