Bad Q6600 or Bad 680i

Hi Gang...

Been running my EVGA 680i Revision A2 with a E6600 at 3.2GHZ on air without any trouble for 12 mths...

Just put a Q6600 G0 in the board and the best I can seem to overclock is 2.7GHZ at 1.325V.

Its deffo not memory related as memory is Cellshock and was never a problem with the E6600.

I have tried to up the CPU voltage to 1.4 volt and FSB for 2.8 GHZ but system fails boot.

I thought the G0 Q6600 were suppose to clock far better ?

Could it be the revision of my 680i board ?

Any ideas anyone ?

Thanks

Hi Again

My bios is indeed the P31...

Yep I did a cmos reset...

Any more ideas, ive tried all the suggestions on voltage increases and to no avail, anything past 2.7 GHZ and its unstable...

Cheers

Seems Like Its The 680i

Hi

It seems my problem is due to the fact I have an "AR" revision of the board which borks like crazy with quad cores...

I have sent EVGA an RMA request and will see what happens...

If the RMA is gonna take a while to get sorted I may have to buy another board as I can not exist without my PC.....

Any thoughts on the P35's and what brand/model works well for overclocking?

Thanks for all the suggestions thus far.

Cheers
