O.K., I'm sure the question on everyones mind now is 'how far will the Q9450 really go?', right? I'll tell you the nitty-gritty from my side of the world-settings in bios and all...
Recently I put together a beast of a system-believe me, blood sweat and tears went into this thing. Did hours after hours of research before finally deciding on going for broke. I purchased the following:
Lian Li A-17
5x 120mm Case Fans
ASUS P5k3 Deluxe/Wi-Fi AP
Intel Core 2 Quad Q9450
Ozc Vendetta 2 120mm Fan/Heatsink
2x1 GB Patriot DDR3-1866
2x 500 GB WD Caviar SE16 Raid0 Partitioned 250/750
Samsung 20x DVD Burner w/Lightscribe
As you can see, with 5 case fans and the Ozc vendetta 2, overheating shouldn't be an issue. Right now I'm at 3.704 Ghz Stable with 1.3625 vcore!!! I know there's more room to play, but I'm exhausted-3.7 already took me 2 weeks of restless nights as it is. I'll get back to it once I've had my break and keep you posted with an edit...
So, your probably just dying to hear the settings already, and I don't mind giving you guys my hard earned time, sweat blood and tears-this has actually been my first build/overclock-I have no problem sharing this so long as you build on it and post back RIGHT HERE. So here it goes...In Bios:
