Has anyone figured out the setting for best watt per GHs ratio.
I thought lowering the frequency would reduce watts/GHs but it doesnt so much in my case.
If I increase frequency to 250 which in my case was stock frequency, my power consumption shoots up to 950 W and output stays around 1040-1100.
I am afraid to run it at that frequency because then temperatures go in 50s.
So I am running it at 225 that gives me between 850-900 GHS  for consistent consumption of 786+ watts and that seems pretty inefficient.
Applying the new firmware from Bitmain support site also didn't make any difference.
Btw, above watts (with 80plus Gold Rosewill psu) also include the cooling kit consumption but taking out 25 watts from above numbers still doesn't match the specs.
