New S775 motherboard.

Your current board should be able to hold off whatever OC you want.

I say just tweak some settings, and you should have it. If not then your chip is at fault.

^ this... That board u have is one of the 775 Kings...

Is there something wrong with ur board?

Are you having issues with your UD3P? That motherboard can easily hold a Q6700 @ 3.2gHz. Are you using LLC? If not you might want to try that. And up the Vcore man! That chip can take 1.4V 24/7 like it's nothing. Actually it's rated up to 1.5V.

It might just be your board. U could try an ASUS board instead.

I'd RMA it - that board is really good, so if you're having problems it's either the CPU limiting it or a fault with the board

Try an RMA first but no guarantees since I think Gigabyte takes a while...

Sounds to me like your mobo is borked. If you've tried everything, just RMA it. If you don't need CF, take a look at the UD3R.

The 775 UD3-series are top dogs when it comes to quad overclocking nowadays, especially for the price.

ok will post my settings when i get home. I dont think that I can RMA it? I'm in the UK and pretty sure I've had the board for more than a year.

The CPU is fine because I have had it at 3.6 stable before but with much higher voltage. I have a different gfx card in the computer now and it works fine. It does lockup for a few moments on occasion but it allways comes back from the frozen screen. This maybe because I swapped to a nvidia card from ati without removing drivers though...

Gigabyte should have a 3 year warranty if I remember correctly. So u should be able to RMA. But if u said graphics card switch helped, it might not need it. U can uninstall all drivers and reinstall nVidia ones and check if it helps.

RMA it. Nothing beats the UD3P. It is the KING!
