Overclocking E2160 with XFX 750i

sli is only good on a higher end rig but (quad cores etc), and im not really a fan of nvidia chipsets etc

check the overclocking section for guides and FAQs before posting questions etc

oh and that 2160 should see ~3ghz btw, and stay below 1.4750v  

I literally just finished some OCing on my Q8200, first time as well. I have the same board you are planning on using. There are some "FSB holes," the CPU won't be stable around 1400 FSB til about 1500FSB, from my experience. You won't need to adjust the CPU voltage much, just the NB and the VTT. Also as apache_lives said, don't go above 1.4V with the VTT (you can go 1.47 as he said but I wouldn't push it.. I think (don't remember and too lazy to restart) my NB is at 1.36V and the VTT is at 1.4V, not quite sure. Make sure after you OC to use the Intel Burn Test to verify stability (google it, first result).

Good luck!

Edit: If you're planning on 2 GPUs, upgrade your PSU to 650w+ and note that the XFX 750i PCIe slots will run at 8x in SLI-mode.

SO XFX 750I won't be a good motherboard for overclocking?If so then tell me the range of the FSB holes of the xfx750i,It would be greatly appreciated..help

They vary from board to board but on mine it was from about 320-330MHz and somewhere around 350-385MHz (guessing about this one because I don't want to OC my CPU more than 370 FSB). They aren't large and are really only an issue if you want to get every last bit out of your components or if you have a low multiplier. If you're looking for a moderate overclock, then for the price (around $90 now?) you can't beat this board. I've had it for about 6 months now and had not a single issue with it.

This should be your first stop.

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.

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

For anything higher than about 3.0 GHz, 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.
