I read a review a while back that said that the Nvidia 680i has a feature that can automatically overclock itself including the memory (Trying to find it again). Has anyone ever tried it? Also I went to the Nvidia site to look up compatible memory. There was a long list, but the numbers didn't look like retail info. I figured this would be good for a gamer like me who hasn't overclocked but wouldn't mind the added free speed benefit.
