Can someone possibly assist me? I have 3 cards that refuse to start hashing. I tried connecting 1 card at a time operating status goes from running to stop before it starts mining. Only 1 card out of 4 works, if i connect it alone it stays running and starts to mine. If i connect it with any or all of the other three cards, operating status goes from running to stop before any minimg takes place. Please help at a total loss. It is not the pi that is faulty
