I'm pretty much ready to give up trying with this CPU now!

I simply cannot get it to overclock, the slightest increase in FSB and the computer won't reach windows. Temps are stable (38c idle, 45c under load @ stock), cooling is more than adequate throughout the case, only 2 sticks of RAM both set to factory settings when trying to overclock, and still no joy.

Last night i defaulted the bios, set the multiplier to 9x, voltage to 1.3, fsb to 1250 (around the 2.8Ghz mark if i remember). Nada.

If anyone can post some tips i would appreciate it immensely, as admittedly this is my first intel processor, the last time i overclocked was an athlon 3800+ which was a simple case of cranking up the FSB. Mobo is an EVGA 680i SLI, for rest of specs see sig.

Thanks in advance

wait what? 1280 FSB x 9 multiplier = ~11GHz.. That may be your problem

never oc'd a quad though, i may be wrong
 
gotcha ;)

set all to default, and then increase +1 FSB.. then try +5, then try 25.. and so-on

See how far you get that way..

Then around 2.8, 3.0 Ghz you may need to crank the juice up.

2.8 should be a cake walk
 
Nvidia chipsets can be harder to overclock with.

You will probably need to bump the northbridge voltage and FSB/VTT voltage.

Didn't the 680i have a huge issue with the Quads?

They did, luckily it was fixed in a BIOS update.

Hmm never thought about the FSB voltage, how much would you up it by roughly?

Thanks for all the help guys i'm going to have another crack at it tonight when i get home, i'll be sure to update the thread. :)

As far as I know, the recent Nvidia chipsets (6x0i and 7x0i) are in general harder to FSB-overclock than Intel chipsets, all other things equal. That said, it is possible to get a decent overclock (I have my Q6600 at ~3.4GHz), but you'll likely have to live with higher voltages.
