I just tried putting power to the board that wasn't working anymore and something went up in smoke. It's dead for sure. : (

That's scary... but at least it's the first and only magic smoke release after going "green ghost" that I've heard of. Two of my four boards are still stuck as LED-less dead weight, but the other two are hashing away stably at about 19gh/s on default settings. I thought I was unlucky yesterday, now I'm counting my blessings to have working boards at all.
