Also does it seem strange to anyone else that the one under preforming miner that has been posted looks nothing like anything in the pictures posted by AMT. 
I've wondered that myself. I have no AMT logo on my miner and it is very clean not like the ones in the pictures that AMT provided.
On closer look though, the board does seem to have the power plug on the same side and the elongated heat sink on the chips side of the board. Also, the power supply does look the same and the pin holes seem to match.
Although, I wonder why they only supplied 4 boards on my machine. Had they supplied 5 like in their picture I would be mining at 1TH/s nominal. Instead I have set the frequency to 900MHz to get an average of 920GH/s on the miner side and an average of 880GH/s on the pool side (http://eligius.st/~wizkid057/newstats/userstats.php/1Pof4JuXwDzvL6BK6r7roKuCmDMUUkghgn).
If I set the frequency any higher the rejected rate goes through the roof and it's like I'm mining with only 360GH/s.
The good thing is that the max temperatures that the miner reports is 45 Deg. Cel. and the boards are cool enough to touch.
If I had 5 boards I could be mining at an average 1.1TH/s at the 900Mhz frequency.
