Voltage shown by cgminer equals the maximum value for 1 core. After a board is powered up it takes some time to enter the active mode. The minimum required voltage for the core to operate without errors is selected automatically.
Power consumption stated in the technical specifications was measured for the whole device as a single unit. The testing was performed in normal conditions (16-24 C) during a certain timeframe.

That image reveals a blatant attempt to deceive. The GN1 chip has 4 dies, each with 96 cores on them. Each clock cycle one core can do two hashes. That gives an absolute theoretical maximum of 768 hashes per clock cycle. See page 5 of the GN Protocol document for proof.

It is a physical impossibility to get 860GH/s from a clock of 950MHz over a couple minute interval.

Also, your WU values (diff1 shares/min) don't match your hashrate. The conversion from WU to hashrate is 2^32*WU/60 (divided by 60 to give diff1/second). Your values do not match at all, and you've likely just edited cgminer to display the wrong hashrate.

I will remove my negative trust once you send a board to dogie and he confirms your numbers.
