I have tried with a working MM board from a good known 841 and still the same thing. Maybe it can be a faulty hashboard, but why doesnt the other hashboards work? I think it is uncomon that all the 4 hashboards are faulty,what do you think?
Hi,
it gives you the ECHU code 131073 in the cgminer API log.
I have explained that particular code here:
https://bitcointalk.org/index.php?topic=5325107.msg57013711#msg57013711It's usually a sign for a faulty hash board.
But if you are sure the hash boards SHOULD be ok,
it can also be a faulty MM board (control board).
Do you have another MM board to try with this unit?
