My X never seemed to like being overclocked and I spent a lot of time and went through many fc's. But, I kept reading about Over Clock program and decided to give it a try. And, so far its been great. Calculated the settings for my particular phone and now I'm oc'd to 1400 MHz and lowered my vsels to the min which seems to be giving me better battery life. Great program and a must to maximize performance. Just wanted to say thanks to the developer and the people here who've been talking about it.
