once the software catches up to these sticks they are going to kill.  I am getting a steady 2.0 from each one.

These have to be asic miners  new block erupters.
 they are the exact same size as a block eruptor .
they have the same id as a block erupter.

first sale of 4000 at 45 btc a case
second sale of 20000 at 33 btc a case

 a shit load of commonalities
 these sticks rock.

6x the hash at less power and stable.

they will bury the bit fury sticks..   2 gh at .075btc vs  2.5gh at .25btc not much to think about.


I only bought 1 unit to experiment with and it has been running stable for over 24 hours on a Rpi.
My stats look like this.
Average 2.409gh/s
A 83568 R 156 HW 369 WU 33.5
I have adjusted the voltage to .9 volts and the clock is set at 300mhz (0B81).
BTC guild stats verify the hash rate.
Wish I had a more units Smiley

I know how to up the freq but how did you boost power?

 I have a lot of 12 volt and 13 volt psu's to use on hubs. 

 I was very pleased to get the 1.98-2.01 gh a stick.  but getting 2.4 a stick does sound tempting
Increasing the voltage involves changing surface mount resistors at R1 and R2.
All the information necessary is in the Over clocking section of AntMiner-U1 user guide.
When I get more time I will try some other voltage & clock experiment's.
Right now I am happy with .9 volt and 300mhz for 2.4gh/s.
