I want to overclock my E8400 to 3800 mhz.What should I do?

Firts of all is it possible with a zalman 7000B alcu with resonable temps and with an ASUS p5n-d ,2GB 800 mhz ram? If yes what settings should I set in the bios.Now I have it at 3.6GHZ with 1.18750 voltage with maximum 65*C with core temp.and 53 with REAL TEMP. CAN I GO HIGHER????

They can hit 4-4.2GHz.

Ya you only need to overclock an E8400 if you have dual 9800GX2's or want more 3dmark.Spybot_9

Or do CPU intense things that only suppot two cores.
