I'm using 10 GTX 1060 in my rig running under Ubuntu 16.04

I get an average slightly above 230Mh/s
I have cards from different manufacturers (EVGA and MSI) so settings may vary.
Usually max power 75W, core clock -200, memory between +1100 and +1600
I have Samsung memory on all cards.
EVGA model is a bargain:
EVGA single fanModels from MSI:
MSI double fan / armorMSI Single fanI forgot to add temps. I'm between 47 and 55°C with nothing else than the factory fan.
I also see an increase. I'm around 12$ day now with 230MH/s on average
Pendra37: how do you calculate the dag limit? I have only 3Gb cards and I know from the start that there will be an end but when is more difficult to predict. Will POS allow 3Gb cards to continue working?
Power meter in the wall indicates 850-900W for the whole rig (motheboard, gpu, psu, ssd, cpu,...)
