Only way it would damage anything is if you were to play with voltages, or your cooler was not up to the task of keeping the CPU cool. I would not attempt on a stock Intel cooler. You are just forcing max turbo clock, on all cores, instead of one or 2. In the case of the i7 2600, you would change the multiplier to 38, and not touch anything else. I ran an i5 2400, with a P67 Extreme4, the same way. Just changed the multiplier to max turbo, and left everything else alone. It is not something you have to do, I just wanted you to be aware of the possibility of squeezing a little more, out of that CPU.
