It would seem that around 3.0GHz is the highest you'd be able to get out of this board as there really seems to be no voltage setting option:

To quote cobraracer's post toward the end:
"You can adjust the pci-e in the bios to 105 and then you can get the Q6600 on this motherboard to the mid 3.2GHz range (set the memory to 667). Any higher than 105 and you will lose your internet, any lower than 105 and the computer won't boot at the 3.0GHz+ speeds.
Since this board only has two memory slots, you will need memory that is capable of 4-4-4-12 timings (either 2 1GB or 2 2GB) to accomplish the jump from the 3.0GHz range to the 3.2GHz range (Q6600). I am running the memory timings on the "auto" setting (5-5-5-15). "
May be you could give what he suggested a try.
I remember seing some one on here a long time ago with a sub 1v VID Q6600

To get 3.6 you would need at least 1.4v and that would be a good clocking Q6600, one with a 1.25 or lower vid
Depending on board and CPU you would normally be looking at between 1.42 and 1.56 vcore to get 3.6gig stable... and really you don't want to be running above 1.45 if you can't afford to replace the chip, tho I've not known anyone manage to kill one short of putting 1.7v on the PLL. I've had an E6600 @ 1.65v watercooled running number crunching 24x7 for around 2 years and its still working fine but I wouldn't generally reccomend it.
I got pretty lucky, mine was a 1.2750 vid chip, 1.4 vcore for 3.6ghz. Had to go to just over 1.5 vcore for 3.8ghz all on air cooling. Albeit i was using a p45 asus p5q deluxe mobo which certainly helped.
Wowzer, wonder if he OC'ed it. Would be a crime not to!
There's an interesting read concerning cpu and gpu bottlenecking here,
If you're running an easily obtainable 3GHz cpu overclock, with a single card, at a reasonable resolution (ie 1680x1050 and above) the only bottleneck you're going to get is your video card.
However if your running two or more cards it's a totally different kettle of fish.

Interesting article coupe, thanks for posting it. Im currently running a single gtx 275 in an i7 at 4ghz, adding a second card for sli this week, (res at 1920x1200). May have a crack at running different clockspeeds on the cpu to see how performance fares.
im going to leave it at 3ghz ,
