The hash rate is quite good.


What about the power? Is it normal? 1100W and 1140W at the wall.

Yes, the power consumption is normal but you can reduce it if you lower the GPU's core clock frequency to about 1150 mhz.

I've tried, but if I go below 1200 MHz my hashrate drops significantly. Few cards I did 1166 MHz and they were ok.

I also tried dual mining but then the power jumps from 1100W to 1400W. Not worth it I guess.

I mined in dual when Decreed was 35-45$, was profitable enough, for about 3 weeks I mine only 1 coin at a time, the power consumption and maximum usage of GPU's are not worth it, I also think they will go obsolete if mining for a long time in dual, not sure about this, I am just sure the GPU's will live more while mining 1 coin at a time.
