Well I finally broke the 3 Ghz mark, have been running Prime95 for 45 minutes, planning on leaving it like that while I sleep. Screenies to come if it's stable.
Highest OC I EVER reached on any CPU was a Pentium 4 Prescott S478 from 2.8GHz to 3.4GHz stable with PC2100 RAM. Damn good overclock I'd say given the RAM.
