I am super stoked. I received my 3x 2PACs today! They all appear to be functioning well straight out of the box with my RPi2 on a 60w powered usb hub. Now, I only need to do a little power optimization.

It looks like I am getting about 6.12w to 6.14w per device with a frequency of 175MHz at the default Vcore of 1.26v. The hashrate for each is pushing about 19.1GH/s to 19.2GH/s after a few hours on p2pool at a manually set difficulty of 32. One of the sticks does seem to average about 1 HW error every 30 minutes. I bet if I up its Vcore one notch it will drop.
I have to say that I am really happy with the current result. Oh, I cannot forget the blinky lights! I love the fact that sidehack includes them. HaHa... He certainly thinks of everything.
