found the problem... the mid card is not in his socket (i dont know if its just a socket or its broken.. can anyone tell me how to place that card in place? or what to do? thank you
Before opening get Bitmain's permission to do it and look at hashing board. Yes this sounds stupid... but they have it where if you open up without permission you void warranty. So big deal when dealing with possible RMA.
But send in a ticket and email and see if you can get that permission.
