I have never OC'ed and i dont know how really, I have

Xfx 750i with a q6700 at 2.66
with Corsair 2048MB PC6400 DDR2 800MH
and a 1200 wat psu
500 gig hd *2
and a 260 gtx 216 core

i was hoping someone could tell me what to set my stuff at to get to at least 3.2 safely

I do have a after market heat sink, itl do the job, and plenty of 200mm fans, so i can keep it cooled!
 
This should be your first stop.
Core2 Overclocking Guide (generic guide)
http://www.tomshardware.co.uk/forum/259899-11-core-overclocking-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. nVidia chips handle overclocking a little differently.

The nVidia 700i chipset is just a 600i chipset that has been modified to be compatible with the Yorkfield quads.

This guide is pretty good except for the section on setting up the memory. What you want to do is set the memory frequency to two times the FSB frequency (which you can't adjust) or one half the FSB clock (which you can adjust). Remember, the bus is "quad pumped". It transfers 4 chunks of data into and out of the CPU each cycle. So each FSB cycle generates 4 FSB clocks.

At a stock FSB clock of 1066 MHz (266 MHz FSB frequency), your memory clock should be at 533 MHz. Try running with memory Linked. As you increase your FSB, the memory freq will increase proportionately. If that doesn't work, run Unlinked and set your memory freq manually.

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