You know that supprised me 2 this is batch 8 . I conected the cabels from the psu to all 3 boards but not the control board. Then i had to take a leak, came back then i saw smoke from the miner... after i reconected everything i saw that the 3 hashbaord shows temp 0 and --- --- . No clue why. Btw i live in Norway.
So what you are saying is that the Hash Boards were connected, Controller not, you then left ift for a couple of minutes and there was smoke coming from the miner?
What did you do then? Connect the Controller or power everything down and start again?
It had been reported in another thread that with B8 without the Controller connected that this results in a v low core voltage?
I noticed that without the controller plugged, the voltage output at the coil was closer to 8v, can't remember exact value.
And, it went higher to 10.2 with the control board plugged
However there may be a difference between a Controller not powered & a controller not plugged in? We don't at the moment fully understand the exact workings of batch 8 with the Microprocessor controlled Buck Controller so in the meantime care is needed.
