HF's document mentions 96x4x2 and 422GH/s at nominal 550MHz. GN on our board provides at least 520 GH/s at 550MHz. The screenshot shows what cgminer shows (with original HF driver) and this is what we are providing. The document by HashFast was composed for their equipment and boards and wasn't updated even after Yoli was released that was 2 steps away from discovering the whole potential of Golden Nonce. Even rev 2.1/2.2 of the boards were able, at certain manipulations with cooling and voltage, to reach results that are not documented by HashFast. That is a fact. This chip has a great potential but not everyone can revise and upgrade the board. Your claim is unjustified.
