Ok, I have an XP 2500+ (Barton) and have been messing around overclocking it. My question is, what is the point of adjusting vcore? Ive overclocked it to 167x12=2.004 Ghz (Runs just fine). Not exactly sure if change the multiplier vs clock rate is better... Why do people bump up the vcore? I'm currently at 1.68 but see a lot of people running in the ~1.75 range. What does this get you? I've kept an eye on the temperature, and its warm (60c), but its a barton.
