post up specs on your rigs. i just started the whole overclocking thing so i'm still learning. overclocking rig: Abit AS8 motherboard Intel 550 3.4HT Prescott socket T Corsair XMS PC3200 2x512mb 2-3-3-6 WD 74gb Raptor PNY 128mb 6600GT so far i've gotten it to 3.857ghz (226x17) on a thermaltake HSF with two heatpipes and a 90mm funneled fan. at idle it stays around 43 deg. my other machine: ECS (peice of crap) K8M800 motherboard AMD A64 2800+ Clawhammer socket 754 Corsair Value Select PC3200 2x512mb 160gb Seagate this one is running at 2.087ghz (232x9) on a stock HSF, the only reason i can't go any faster is because the board won't let me set the multiplier or the FSB faster than 232.
