dude 4GHZ is not really much, my bro gets his 3.2 to like 3.8 on on stock voltage. i can finally get my 2.6 to 3.2 easy. You have a 700MHZ overclock, this one guy at another forum i am part of got his 2.4a to about 4GHZ yeah, thats cool(on water) and this other guy got his 2.4a to 3.6. Yeah those 2.4a's OVERCLOCK xtremely. And if you dont believe me i will prove it upon request.
