As always we will try to reduce the voltage, which will make sense especially with such an high VCore. We encourage you to do the same, if your board does support it, because it will shave off some bucks of your power-bill, will keep your system cooler and there is no other disadvantage. The Cool'n'Quiet voltage will not change, but you see we can manage the stock 2.60GHz with just the idle-power.
The more interesting part now is if we can overclock while under-voltaging and find a good balance between power-consumption and clock speed. The best we could find was 3.0GHz at 1.2500VCore which is still considerably below the default VCore but with a much more appealing clock speed.
