I am rooted, running CM7, and I think I want to take the plunge and overclock. I didn't want to start screwing around without knowing what I'm doing/what I might change. How do I go about doing this? There's a lot of options in "Performance Settings" as well as "CPU settings" within it. What is "Compcache RAM usage?" What should I/could I mess with to make my phone a little more responsive? Thanks.
