Step one is ALWAYS isolate the problem. Unplug the working boards and see if the problem persists. Next, try the card on a different controller channel. If step one fixes your problem your power issue is your power supply(uncommon). if step two fixes your problem your problem is either the controller for the cable itself(pretty rare). If your problem persists, your hashboard resident buck converter is screwy and needs to be repaired.(common)
Hi MinerMedic.
They are all new and with PSU from bitmain so it could be the PSU but i doubt it.
Ive neen power cycling the miner and that actually made it worse where the patten failiour "spread" to another board.
After som soft reboots i got back to where the 2 hash boards are running but 1 (lets call it nr. 1) failed the test patten and isnt running.
it shows in the status and kernel log but when it tries to list the asic cores in the log it shows non.
I was/am afraid taht the boards is faulty.
I will try the switching of the cables later tonight when i get home - just to test if its the controller / cable.
the last part i didnt get - you meen that a buck converter is faulty ? how can i fix it or is it a thing that they need to do for me ?
Thanks for the help
