Running into some zombification as of last night. Tweaking frequencies and the voltage dial to see what's up, but for now it seems happier at 150 MHz than 175. Also, it apparently doesn't like a voltage much higher than what it was set to originally, but I did get it to 200 MHz for a brief period. I think it also might no longer like the USB 3 extension cable I'd been using, but for that, I need to do some difficulty adjustment tests, since I'm not sure if it stopped mining or timed out finding shares in that instance.

Still, I'm impressed with the device's ability to recover. It's nice working with something that's volatile-memory-only again.
