i cant really get very far. my default fsb speed is 133, the highest i can get to 137, even this causes 3dmark2k1 to crash to the desktop, but everything else is fine. i managed to get to 140 and it looked mighty nice seeing XP 2200+ in the system properties, although, it crashed the second i ran any utility. at 137, although 3dmark is unstable everything else is fine, so far. plus it says xp2100+ which is that much more satisfying than seeing XP 2000+ . oh well, maybe i should increase the voltage/memory/or agp to help increase the fsb a little higher and keep things stable. ive read many ppl with stock cooling, reaching increasing the fsb ti 145, with similar specs to me.
