I just got a Geforce GTX 660, and I was interested in overclocking it.
Using Precision X, I got a 400MHz DDR overclock (200MHz Base, 800MHz QDR), but, remembering that my rear memory chips are unsinked, I've decided to hold off until I can get some RAM sinks.
So my main question is this: Does raising the clock speed alone increase the heat or reduce the life expectancy of the card, or is this only caused by over-voltage?
I mean you figure, on one hand, you aren't actually changing the voltage, so the power distribution should be about the same. On the other hand, more clock cycles translates into more precharge cycles, translating to more current, more power, and thus more heat.
