@Battlestar: I am also missing the area indicated by red box, however, I just used the graph and bumped the minimum up, and steepened the slope some. However, Sensors (page in GPU-Z) doesn't accurately report GPU speed when operating in 3d mode, just sits at 500 all the time... Not sure if this is just cause its early, or what.

Also, my down clock to Power State 1 (power play 2d setting) doesn't change clock speed at all. So I'll try another setting... Perhaps I just have to use the right numbers. Can anyone confirm if changing voltage in Bios with RBE actually works? Or are we bound to mod for voltage tweaks?
