@Claymore: There seems to be a bug with the -li parameter.
R9 Nano does 100 H/s with stock ROM, pulling around 200W.
Since I prefer more silent operations, I use -li 2 and it does 75 H/s at 160W.
But... after some time the hashrate drops from 75 H/s to 60 H/s in this -li 2 mode.
I noticed it because noise level dropped, so fans spinned slower. However, as soon as I connect to each rig over Teamviewer the miner speeds up again to 75 H/s per card.
I am puzzled since all energy saving crap is disabled on these rigs and they work since a year without any such problem on many other coins.
I have not tried -li 2 on previous versions because it wasn't necessary before v 4.0
If I keep Teamviewer open, the speed won't drop and it remains at 75 H/s per card.

This time I used -li 1 so they hash at 90 H/s but still drop to 60 H/s when Teamviewer gets closed. With -li 2 they do 75 H/s and drop also to 60 H/s when Teamviewer is closed.
