E8400 Refuses to Overclock!
Just today, i got a new Antec 900 and a Xigmatec s-1283 heatsink for my E8400. (if you want my specs just check my sig.) The chip works wonderfully up to 3.8ghz, where it seems to hit a wall. it will do 3.6ghz on stock volts, and 3.8 on only a very small voltage bump.
Now does somebody want to tell me why i can't hit 4ghz?!  I have pumped 1.42V through this chip (excessive, i know... but my temps are under 65C load) but no matter what i do, Orthos or Prime95 fails within 15 seconds. i have loosened my ram's timings to 6-6-6-18 @1000mhz, which is plenty for the sticks i have. The ram is set to 2.4V as per OCZ's recommendations. I have tried changing my northbridge to 1.4V, but that made no difference either. im pulling my hair out here! i've heard of people getting to 4ghz on 1.35V easy!

 J/k. I have read that some of E8400's dont Oc clock as well as others.This includes some members on these forums.It might be just luck of the draw.I may be wrong but I think omega had one he had trouble hitting 4.0 with.And Some people get one that Oc like Mad like the one Thatguy16 has |

Yeah whether you have a dual or quad core from the graphs I have seen as long as you get 3.4 or better the fps gain is minimal |

with a few hours of effort, i finally read that the C0 stepping loves high voltages. so i changed it to 1.45 in the bios, and its a miracle! stability!
