Is that measurement of 12.08V made with the S7 Hashing, and what about the other 2 Hash Boards, they do not seem to be powered?

Yes. Without hashing its show 12.26 V 2 of boards with Hasrate http://imgur.com/a/ekRYmI think that last board has some problem |

Question bradli?
When the miner is fully plugged up what is your PSU configuration? Is it a single PSU or multiple? If multiple what are you driving with each supply?
Definitely you have a low reading on one board, was that measured when powered from the same PSU wiring as the other measurements? Tha is to say is it a PSU / wiring problem or is that board taking more current?
As well as individually powering boards & making measurements it would be good to fully power up the miner, set it hashing and then make 3 measurements directly into the board sockets as you have shown?

OK well that simplifies things.  So the board with the < 12V was that measured using the same connector cables as the other measurements? if so then that board must be taking quite a bit more current than the others? Is the temperature higher on that board? I think still worth fully powering the miner and then measuring voltages on the 3 board connectors. Rich |

I ve manage my psu server 2000w to do 12.5-.6 V.
In power hashing - 12.25-.30 V.
600- 4.7-4.75 TH
Its better from before.
