Hey guys, so far I only mamaged to overclock my e8400 proc to 3.15GHz..(1400 FSB). Weird thing is, when I try smaller increments (1410, 1450 etc) I won't even get to the POST screen sometimes after restart but if I go straight to 1600 Mhz, then I get to the point where windows finishes booting ( the moving bars thing disappear) but the next screen fail to display. Right now my cpu temperature is around 45C with intel stock cooler (lazy to buy cooler la..)

So the thing is, I dont' think it's the heat right? Could it be not enough voltage? I see most ppl can oc their e8400 to quite high, at least 3.6ghz.
