I'm currently running stable actually 
, giving me an average of 63Gh/s, with the following options. --bmsc-voltage 0830 --bmsc-freq 0982

A couple of days. testing out different options/tunings in a not so structured manner;)
reducing volt to 800 and keeping freq and --bmsc-options 115200:0.54, see what i'll average on then.
Got my second unit up and running on Minera on a new Pi 2 now as well. Always had issues with that one, only giving me around 42Gh and a bit unstable.
But minera seems to handle it quite well, had some fall outs untill i enabled auto restart/reset. So far quiet happy with minera, expect i havent been able to get any of the parameters for tuning to work. Picked up the U3 like nothing at least.
