Well, I'm overclocking it. I detected the optimal frequencies, and here's how it came out.
Core clock: 500MHz
Memory clock: 1.2GHz
Temperature: Playing Doom 3 - 55 Degrees Celsius.
Playing F.E.A.R. - 61 Degrees Celsius.
I'de say that's pretty good, wouldn't you? I'm going to set it back. Don't really need to OC even more.
