ok here's my setup...

Abit AS8 motherboard
Intel 550 3.4HT LGA775
Corsair XMS PC3200 2x512mb 2-3-3-6
PNY 6600GT 128mb AGP
WD Raptor 74gb

i've been using clockgen for the AS8 and my system crashes at around 3.8ghz, i have a thermaltake HSF with heatpipes and a 90mm fan so it stays around 43 deg celcius when it's at 3.8ghz. are there any tips anyone can give me to help me figure out how to overclock better?
