Overclocking? Yes, quite a bit of head-room for that!

Without any increase in voltage and bumping up the multiplier up to 13x from the default 10x (The Multipliers on the QX6700 are unlocked upwards and downwards by the way), the QX6700 we have on hand has no problem doing 3.466GHz fully stable. That's a 30% increase in clock speed on a Quad Core Processor that easily! After the whole session of testing I retried this with the default air-cooler instead of the Ninja and I had no problems keeping it 100% stable at this same speed. Simple pressing of the + button three times in the BIOS screen got me 25% increase in performance!

 

Bumping the voltage up to 1.45v, and cooling the CPU with the Ninja Tower Cooler, 3.73GHz fully stable is no issue. 1.07GHz extra Quad Core performance can be realistically expected on the QX6700 if you are running a decent air-cooler setup. I find that the processor is quite sensitive to temperature, more so than voltage at normal air-cooling temperature, as 1.55v makes it less stable due to heat.

There are some issues with the Kentsfield and high FSB runnning so I tested out the maximum FSB attainable on it.

356MHz FSB Air-cooled... but at 3915MHz it is definitely not fully stable with just air-cooling. It does seem that the 400+ FSB we have been seeing on the Core 2 Duos may not be as easily seen on Core 2 Quad, unless perhaps the BX2, revision 2 holds a surprise in this department.

Well, this session of overclocking was a rather effortless try. I shall continue with Water-cooling next and then perhaps even more extreme cooling.
