More Q9450 overclocking

I know there is already a Q9450 OCing thread, but it is pretty off-topic, and pretty inactive. So, I am a first time builder, and just ordered my parts today. I am getting

■Intel Core2Quad Q9450
■Asus P45 P5Q Pro
■(2x) 2x1GB Crucial Ballistix DDR2 800
■Radeon 4850
■TV Tuner Card
■AC Freezer 7+ Arctic Silver 5
Of course, there is more stuff, but I think this is all that matters. I don't plan on overclocking this very far, 3.5-3.6 at most. I still want this to last a good amount of time. Can anyone give me some tested voltages and speeds. Normally, I would experiment a little myself, but I first of all do not want to risk damaging my machine at all. (Like I said, I'm not getting another rig for a VERY long time.)

Thanks for all the help!

EDIT: My case is the NZXT Tempest, which I think has 6 fans.

Its a good question. Sorry that I do not have an answer for you. I am in the same boat as you are. ASUS P45 P5Q Deluxe, Q9450. I was looking how to overclock myself when I saw your thread. I too would like to know the best way to OC my CPU. As for Paris Lee, gee thanks. I wanted advice on how to OC, not on having to wait for the next gen CPU. Thanks for playing, see ya!

@paris: I already ordered my parts, so thats out of the question.

I have decided maybe I will just go for 3.4Ghz, because it needs to last for a long time. At 3.4, the FSB will need to be 425 (*8). The CPU has a FSB wall of 450, so I am still on the safe side. Obviously, it won't be just as simple as changing the FSB to 425. There has got to be some voltages etc. that I need to change. :(

I made it to 3.2 on stock volts so you should be able to set it to 400 FSB 1:1 ratio PCIE 100mhz and boot. Make sure to turn off all the intel speed step stuff CIEST or what ever it is called.

blerb, I believe unless your ambient room temperature is very low (your room feels cold) you may have some high temps with 3.4Ghz on a Q9450 with an Artic Cooling Freezer 7 Pro. ...shoulda had a Xigmatek S-1283 or one of its brethren. The ACF7P is a good cooler but not best suited to overclocked quad cores.

@iluvgillgill the max on a Q6600 is not 3.2ghz, I run mine all day long at 3.6 on a 790i Ultra Board, using a Ultra Chilltec Thermo Electric Cooler. There are several others who I have seen at even higher frequencies once they go into water cooling. It has been known to run stable to 3.8GHZ.

My Vid is 1.2250
My Vcore is 1.45V (Vdroops to 1.40)
FSB is at 400/1600 FSB @ 1.35V
Q6600 @ 9x multi
Idles @ 38 Cel.
Max Load Temp @ 65 Cel.

Hope this helps in someway

Okay. I have the computer all built now, and I am stable at 3.2Ghz. But the voltage is set to Auto, so I am probably getting higher temps than necessary.

My temp sensors may be stuck though, because it seems that while temps may vary through programs, Core 0 and 1 are always the same as each other. That is not to say they don't change, but they are always together. Cores 2 and 3 are about 10 degrees less than what 0 and 1 are at. Seems a bit odd.

I know, multi is at 6. I forgot to turn of C1E or Speedstep, whatever does that. (Just updated BIOS)
