Went to check speeds tonight, saw this on one of the miners:
Rebooting doesn't change it, what are the troubleshooting steps to take from here?
1) The loss of the temp sensor suggests it may be do with either power into the board (all), or its cables to the controller.
2) But the lack of mining on the other suggests the controller
3) Put it on its own PSU, so the Evga 1300 temporarily.
4) Put it on BTCGuild for now.
5) Try swapping ports the board connects to on the controller
6) Then try swapping a cable from a known working miner and see if the problem moves.
7) PM me your order number so I can check warranty status please.
That should be enough for now.
