The UberMix 3.1 only gets you to 24?

What if you take the 1625 timings and run them through nerdralph's tool?

Keep in mind that some of these guys have highly tuned timings that they've been testing and optimizing...not just some copy/paste jobbie. And some of them have been able to overvolt the VRAM and therefore I assume can get higher mem clocks/tighter timings than us normies. Unless you are willing to pay someone for a mod or learn how to directly control the VRM I wouldn't expect to get 30+MH/s.
