That's the ticket!
For example, on stock voltage(1.35) I can go from 2200 to 2500MHz and still have the same temps. If I try to go over 2500 it becomes unstable. If I want it to be stable I have to raise the voltage, and that's when temps start to rise.
As CrazeD and others said, raising the speed alone isn't going to damage anything. All that will happen if you raise it too much is you won't be able to POST and you'll have to clear your CMOS and start over.
