Overclocking Intel Q9550 and maybe other hardware

Hey I'm wondering if I could overclock my Intel Q9550? I currently have nothing overclocked at the moment but I want to overclock some of my parts since I'm replacing them by the end of the summer.

PSU: Corsair 750 Watt Power supply (http://www.newegg.com/Product/Product.aspx?Item=N82E168...)
Mobo: EVGA 750i SLI FTW motherboard (http://www.evga.com/articles/401.asp)
GFX Card: BFG 285 GTX (http://www.newegg.ca/Product/Product.aspx?Item=N82E1681...)
RAM: 4 sticks of DDR2 RAM rated for 800 Mhz each being 2 GB (http://www.gskill.com/products.php?index=61).

My CPU heat usually ranges from 50-60 Celsius. However my graphics card goes from 50-60 Celsius when I'm not playing a game and the fan speed being at 100%.

I'm interested in getting more power from my computer, so tell me what is possible with my rig.

The short answer to your question is , YES. However you will need to educate yourself on how to do that. This guide has the method and terminology you should learn before attempting an OC on your CPU. You will also need a better cooler than stock and almost every Q9550 I have seen will do 3.83GHz easly on air.

I run my Q9550 @ 3.83GHz with an earlier version of this air cooler.

The other limiting factor involved with a stable OC will be your hardware as no two are exactly alike.

Just remember that there are no short cuts for OCing that CPU. The more you learn about it the better you will be able to OC and trouble-shoot when things go wrong. You are attempting to OC 2 dual core CPUs on one die, it is not a true quad in the comparasion to AMD quads or the new i series Intel quads. If either of those 2 CPUs on 1 die get just a little out of sync with one another they become very unstable.

I use my Q9550 as my back up PC and like it much better OCd than stock. :sol:

Yup I had a q9400 at 3.8 for several years and it was great. Only had an 260GTX but wasnt allot I couldn't run back then. just up the fsb think I was in the 450 or 475 range. You will need 1066 DDR2 if you want to run the fsb 1:1 with the ram. Not allot to it bump up the voltages till stable. As for the Video card get EVGA prcision and tinker away run firmark after each video card setting and you will see how stable it is.

This is the cooler I have on my CPU



Is this any good? I'm kind of worried though that I didn't do the thermal paste right but I redid it 5 times to be sure.

Make sure you understand the guide and what you are trying to accomplish. The guide that arthurh linked to is for an Asus motherboard.

nVidia chipsets overclock a little differently.

You change the FSB clock, not the FSB freq. And you can run the memory linked or unlinked (to the FSB).

So set your memory to "Linked. That will maintain a 1:1 FSB:RAM ratio.

At stock settings, FSB clock will be 1333 MHz. Mem clock will be 667 MHz. FSB freq will be 333 MHz (for reference only - you cannot change this).

At a 400 MHz FSB freq (1600 MHz FSB clock), your core speed will be 3.4 GHz. You should be able to reach this.

At this point, your memory is running at max rated speed. You can push the memory past its ratings. Increase the memory voltage to 2.2 volts. Then, if you still need to push the memory farther, you can relax the memory timings. Change the timings from 4-4-4-12 to 5's-15 or 5's-15 to 6's-18.

Core2 CPU's are relatively insensitive to changes in memory timing.

Do not exceed 1.45 volts CPU core voltage or 70 C load temps.

Here's the directions I use to apply thermal paste:

I do not overclock GPU's. I figure that they run hot enough.
