|I assume that is a Q9650. I assume that by not including your board make and model, your memory make/model/speed/amount, your power supply make/model/wattage, Cooling method, current temperatures, and more information as well as what you expect out of your overclock, that you are not yet ready for overclocking.|
Read, Read, Read. Google some more and Read, Read, and Read some more.
Do some more research and gather your system information, and try again.
Note that if you are running a stock mfg system (Hp, Dell, Gateway, etc.), or at least the original motherboard from one, you are out of luck, they are not overclockable.
You have to be a little bit crazy to keep you from going insane.
