I am presently running both with all 7 boxes checked and no flags. No flags because I am using the computer.

First one stays at 415.8 Mh/s (occasionally increases ~1Mh/s),
second one is the same almost all the time and only varies ~5 Mh/s, probably because that's the one my monitor is connected to.

Is this a good rate? Or should it be a lot better? What can I do to optimize it?
