@rockmoney Thanks, I'm just glad to be mining again, if I can help...I will.

@sidehack I appreciate you leaving it up to me. As I said, there is no discernible difference between the functionality of the four units aside from the blinking lights. I targeted 600Mhz and they've all settled right around 565Mhz +/- 2hz with voltage setting 5 (440mv). KanoPool is showing me with a share rate of 3.37TH/s and a hash rate of 3.03TH/s. So, as far as I'm concerned, these units are working exactly as advertised. That said, it would be nice if the high temp warning indicators were fully functional. I'd be more than happy to ship the units back especially if it would help you out in any way moving forward. Just PM me with directions if you want to take a look at them.
