I sent them to you running the full power firmware. I was able to flash them to the 1V without any issue, but they slowed down to about 30GH/s on that. Granted they ran much cooler as well (55C instead of 70C) but I'm not paying for power so the draw was never a concern for me. I think I mentioned this, but in case I didn't they tend to top out around 33GH but once you get some air moving over the side of the board you'll get into the 38GH range. Glad you're liking them!
That mess o formatting is what I got from running screen /dev/ttyUSB0 then zcx
