Any idea why it does this and how I can fix it?
yes I have an idea how you can fix it - stick with your teamredminer - continuously.
The thing is that with the same settings and the same watts from the wall, the phoenix has 55.5 mh on each card and the teamred has 54 to 54.3. I have seen that what the miners report in software is also reported in the pools. 1 to 1.5 mh per cart per day for 5 gpu may not say much, but over time it is a significant difference. So if I manage to stabilize phoenix it would be good. Of course I will prefer stability from the few mh above.
So anyone some idea?
