Sorry, didn't realize I could flash remotely. Thought I had to pull the controller and use an SD card on the Beaglebone ARM. Tried remote flashing, works great, so I'm happy I can keep up with your new versions remotely.
Still interested in your thoughts for ideal settings for a data center environment.
It really depends on the power costs per kwh. But probably 17 Mh/s per unit (needs a voltage setting ~5 to ~9 I think) would be a sweet spot. It keeps things a bit cooler compared to the default firmware and makes sure you will have less failing units over a period of 2 years I would say.
