Hi


Now I have 850W at 1000GH at 0720 voltage with 250 MHz freq

I use SD-C1-20141126.tar.gz firmware and try down voltage to 0600 with 100Mhz freq, save and restart.

But energy efficency is the same - about 0.85 W/GH  - 322 Watt / 400 GH

I want 0.5 - 0.6 W/GH,   so I want 200-240 Watt at 400GH

Is it possible with Antminer C1 ?

Does voltage changing should change power consumption? This is not present in my case.
