ok i have a custom build and i want to overclock the q9300 but i havent decided hor far yet, i am looking for a moderate oc that wont damage or shorten the life span of the cpu, the build is:

-VisionTek 900244 Radeon HD 4870 512MB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Retail

-COOLER MASTER RC-690-KKN1-GP Black SECC/ ABS ATX Mid Tower Computer Case - Retail

-Western Digital Caviar SE16 WD6400AAKS 640GB 7200 RPM 16MB Cache SATA 3.0Gb/s Hard Drive - OEM

-CORSAIR CMPSU-650TX 650W ATX12V / EPS12V Power Supply - Retail

-G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop
-Memory Model F2-8500CL5D-4GBPI - Retail

-DFI LANPARTY DK X38-T2R LGA 775 Intel X38 ATX Intel Motherboard - Retail

-Intel Core 2 Quad Q9300 Yorkfield 2.5GHz LGA 775 95W Quad-Core Processor Model BX80580Q9300

-XIGMATEK HDT-S963 92mm Rifle CPU Cooler - Retail

would love to hear any thoughts about ow for i should overclock it and how to go about it

A good rule of thumb "...that wont damage or shorten the life span of the cpu" is to boost the speed 10% without increasing the voltage.
However, since the normal lifespan of a non-OC'd CPU under normal use (not 24/7!) is likely a decade or more, somewhat shortening the life span of a CPU by OCing it may not be a problem in practice. I think most would agree that any OC you can achieve without boosting the stock CPU voltage is likely to be quite safe with adequate cooling. Note that leaving the CPU voltage on "auto" is NOT the same as keeping the CPU voltage at stock, since most current BIOSes boost CPU voltage along with the FSB speed when set to "auto" or default.

well i want to get it to a 3.2 if i can without killing the processor, what would be a way to oc without hurting it i mean im ok if it doesnt last forever but i want the processor to last for aat least 5-6 years if not longer. i know that the q9300 has a locked multiplier but i just want to get it to 3.2. how long would it last at 3.2 and how low would i have to go to just cause a little more heat and not damage it

If you want the CPU to last 5 years or longer (which seems a bit silly to me for an OC, but it's your CPU), then don't boost the voltage over stock.
CPUs vary from chip to chip and this is a new design that hasn't been around long, so nobody can tell you how long it will last under different conditions. All we know is that Intel warranties the CPU for 3 years when run under normal conditions.

Nice build! Btw i would switch for the 750w psu in case you wanna crossfire.

oh you bought already.. nwm you can still crossfire cause it's a great psu

well i want the cpu to last for at least 3 years at minimum before i have to replace it. would like to keep the build around for longer if i can even if i do get a better build i always have uses for spare computers. but without changing the voltage how high could i expect to boost it and still be stable, i most likely wont end up crossfiring but who knows what the future will bring, if i need to get the 750w psu then i will when the time comes along but this build fitted into my immediate price range anyone have any more cpu suggestions or tidbits of insight?

ill have to do that once i get all the parts in, there sporadically arriving in the mail over the next week, just trying to get it all sorted out before hand
