I did this all with nvidia system tools.

I'll let them run like this for several days, and see what impact it has on the credits/day. As you can see, they have been very constant at stock speeds.
Well, adding the 580 completely messed up that chart. In any case, I looked at the individual charts for the three machines with 8800 GTs. Two of the charts are below. The third is meaningless because I stupidly merged hosts during the trial run. No change that is noticeable. Sure, a 2% increase is not much. But I think a more significant influence on the daily credits, is just when a particular task finished WRT the dateline. I will try another 2%. If it still works, and if it still makes no difference, I will go back to stock. Might as well save electricity. That is real $.
