Well I got the SuperBpag hub.
First I connected it to the RPi2 and set the freq at 160.  The Moonlander ran for about 3 hrs at roughly 400 kh/s.  Then is started drifting out and finally going dead. I have tried all sorts of freq and adjustments and it will not run very long before slowing down and then going dead. I have adjusted the diff manually, tired several pools, (LiteCoinPool, LTCRabbit and Clevermining) also made sure there was lots of air from two different fans blowing over it. 
Just cannot keep them running solid for more than a couple hours to sometimes even 10 mins before it goes dead.

I then tried on the Cubieboard with the same results. Then I tested on a PC with the same issue.

Very strange.

Any suggestions to keep them live??
