Alright, so I've never overclocked anything before, and I've been trying to get a handle on it.

This is what I have.

E6700 2.66Ghz
Asus P5N-E SLI (1066 FSB max)
4gigs of DDR2-800

I'd like to slightly overclock my CPU to around 3Ghz. Let me see if I have this right...

FSB is 266.5 (* 4 =1066)
Multiplier is 10

I cant up the multiplier evidently, so I turn it down to 9, and up the FSB to 333(1332)
333*9 = 2.99Ghz.

What exactly do I do with the memory? I see the option to unlink.

Is this possible?


Do your homework and read the sticky guides on the Overclock forums - no one can do that for you or make suggestions with such small amounts of information.

You have a great chance of burning up system components if you start juicing stuff up blindly.

You need to make sure the PCI-e is set to 100, turn off the speedstep junk, manually set timings and voltages and so on.

I recommend you put a good CPU cooler on before you even start, and download the programs to test your temps and components. No one can help untill you give temps, voltages, et cetera.

First you need to ask yourself, do I need to O/C this rig?
Then ask yourself what do you want to do with that O/C...gaming,extracting,encoding,etc......
What video card do you have and can it handle the increased data flow....or is it choked out at stock?
Pleases give us more info on your system and what you want to do with it....
This should be your first stop.
HOWTO: Overclock C2Q (Quads) and C2D (Duals) - Guide v1.6.1

This should be your second stop. You need to know something about thermal management or you can fry your CPU. It's actually kind of difficult to fry a modern CPU, but it is possible.
Core 2 Quad and Duo Temperature Guide

Third stop will be a guide for your particular motherboard. Google is your friend.

You should be able to reach 3.0 GHz with a stock cooler. For anything higher, you will need better cooling. Here are two under $50 heatsinks that are pretty popular:
Xigmatec Dark Knight

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

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

Go through the first two threads. Do not do anything until you have a good idea about what you are trying to do. Once you have definite questions (you will, you will :)), come back and ask.

Keep in mind that these are guides, not cookbooks. YMMV. Your Mileage May Vary. Because of all the variables, you may not do as well as someone else with a similar system. Or you might do better.
