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.
