While the risk is low, its still possible for you to change the wrong setting and fry your machine. Bump the voltage up to far and poof, there goes your new machine. I only help people who know what they are doing. Read some OCing guides and come back. Tell us what you plan to do and I'll tell you if thats a good idea. I don't want to help you kill your stuff. I also don't want to use terms like FSB:RAM or drop the CPU multiplier and have you not understand what I'm talking about. I'm not reinventing the wheel.

Sup Mark :hello:

Not A Bad System! ;)
What Do you want to do?
Do you want to improve load times or FPS?
Must it be stable or do you not mind if it goes poof?
Ive read a couple guides And ive done it all myself but im just reminding you... OC-ing Can kill your whole machine! warantees will be voided!
GIve me a post back if you still want to Chat OC

Because you are new:
This should be your first stop. (Same link as 4745's)
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.
Also look for a generic 680i guide. The 700i's are just 600i's that have been fixed so they can use the 45 nm Yorkfields.

Go through the guides. Then take your core voltage off Auto and set your memory voltage to factory recommended values. Change the memory clock freq to whatever you need to set it to twice the FSB. Then when you increase the FSB, the memory clock will rise in in proportion with it. At an FSB frequency of 333 MHz (1333 MHz FSB clock), your memory clock should be at 667 MHz.

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

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.
Suggestions for applying thermal compound:

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

That should be enough to get you started.
