For no reason all boards are hashing and no resets for over 12 hours. I changed nothing but for some reason it's all working ATM. I would feel more comfortable if I knew what and why this is all happening.

It's getting cold this weekend? I'm starting to think issues being reported are heat related. The unit I had brought up from you has been running without issue since I powered it on 10 hours ago. The first thing I did when I received your unit is tighten any loose screws. Next I flipped the handles around to give the outside chips some breathing room.

For those still experiencing issues after doing these 2 things, I suggest moving the units to a cooler environment or lowering the clock freq.

handles out really takes a lot of heat away from those outside chips.  At least with the small tubes it did.

  I was thinking a lot about the controller it can handle 5volts to around 13volts.  There is a voltage regulator inside of it.  I know the real voltage is closer to 5 volts  then 12 volts.

so if you feed it 12 volts the regulator will make a bit more heat.

When I used the controller with 5 volts 1amp  I let it stand up.. kept it cooler
