Hi Evans This is only for the ATLAS compilation, which compiles (basci linear algebra routines): http://en.wikipedia.org/wiki/Automatically_Tuned_Linear_Algebra_Software
It is perfectly safe, and recommended to get better battery life, to turn the CPU frequency back to "on demand". Most of the time your CPU might run at 800Mhz, but as soon as you click on just about anything it will step up to whatever is needed to, for example, open that window.
