This should be your first stop.
HOWTO: Overclock C2Q (Quads) and C2D (Duals) - Guide v1.6.1
http://www.tomshardware.com/forum/240001-29-howto-overclock-quads-duals-guide

Next stop should be a guide for your particular motherboard. Google is your friend.

Go through the guides. Then take your core voltage off Auto and set your memory voltage to factory recommended values. Change the memory frequency to twice the FSB. Then when you increase the FSB, the memory clock will rise in in proportion with it. At an FSB of 266 MHz, your memory clock should be at 533 MHz.

Download CPU-Z to check your FSB:RAM ratio. It should be a 1:1 ratio.

You can run your FSB freq up to 333 MHz without outrunning your memory . And at 333 MHz, your core speed will be 3.0 GHz.

For a serious overclock, you will need better than stock cooling. Here are three under $50 heatsinks that are pretty popular:
COOLER MASTER Hyper 212 Plus

Xigmatec Dark Knight

They all require a somewhat different approach to applying thermal compound.

And they are pretty large, so they might not fit inside your case.

A 333MHZ FSB Is what your Processor will Be, set at default. So change The multiplier to 9X instead.
If you want to Go faster you will have to get better RAM.

Good Luck!
