Overclocking DQ6 (680i chipset)

Evening all

Was wondering whether anyone could offer any advice on overclocking this board. I just bought one on the back of rave reviews (re overclocking potential) from the likes of Tweaktown etc and on my first attempt, it failed to make it through (even) a 3dMark 06 test.

I have a couple of issues here.

i) CPU-Z is showing a core speed of only 1600 (my chip is a C2D E6600 - 2.6ghz) and multiplier of 6!! The bios shows the clock at 266 and 9 multiplier. Any idea why cpu-z is reading these numbers?

ii) With reference to the first failed overclock, I got the blue screen of death whilst at the second CPU test in 3Dmark 06. Is the blue screen normally attributable to Ram or CPU or even both? Being such a good overclocking board I though I could push the cpu up to at least 2.8Gig without touching any voltages whatsoever. I was wrong it would appear. The overclock failed at 2.57 - pathetic I hear you cry.

Ram voltage / timings all untouched (Corsair XMS 5400) and CPU stock voltage.

Grateful if someone could get me started in the right direction with the various settings required.

Many thanks in advance ;)

First thing is disable speedstep and any "spread spectrum" options in the BIOS.

And try again.

thanx mate I'll look for that and try it.

Any thoughts on what sort of ball park overclock I could achieve without touching cpu voltage? Could I reasonably expect to get to 2.8Ghz without additional vcore?

Further, just reset to stock setting (FSB to 266 on 9 multiplier) and had a further blue screen shut down in 3D Mark. Any thoughts on what could be causing this at stock settings. Is there a problem with compatibility of the ram and this mobo? Is the aforementioned shut down symtomatic of ram problem?

Really appreciate any advice. Thanks :)

From all accounts the new E6600 are not as good at overclocking as the older ones. Just bump the voltages a bit and see what happens. My 6400 in a Evga 680i does 3.2 @ 1.38v where it took almost 1.5 to do it on a P5W DH. Also increase the memory volts to 2.0.

For a good overclocking guide have a look at the evga forum, theres a sticky at the top. It might not be 100% relevant but it'll point you in the right direction. I also assume your flashed to the latest bios.
