i use oryginal bitmain fw now.
when i set 400 M system dont se chain 1
when i set 350 m system se chain 54 chips but not mining
AntMiner
Chain# ASIC# Frequency GH/S(RT) HW Temp(PCB) Temp(Chip) ASIC status
1 54 350 0.00 0 0 0 xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx xxxxxx
2 60 350 4434.28 0 23 33 oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooo
3 60 350 4281.28 0 22 31 oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooo
This is then a hardware problem. I am afraid you have to RMA the first board. My advice to keep mining on the two other boards (the latest custom firmware can run with 2 chains connected)
There is no reason to send it back to china is expensive to send and collect + time ti waitng.. So what one chain go rubish ? or there is posible to fix it ? .. i change place chain and show the same

So i thing yes chain is broken .... Where i can diagniostick one chain or fix ?
