[walkeraki]

Hey,
So i see one of my chains isnt working.. It does not appear to be any broken chips as everything is "O"
Any solutions? I tried restarting it..

A copy of the kernel log would be helpful in this manner, we will not be able to help from that screenshot.

It looks like your first hashing board is not running properly and maybe the hashing board gets too hot that leads to thermal protection so that the hashing board stopped.

Could you perform a factory reset?
Follow this method and maybe it can solve your issue.

• First restart your miner then wait for 2 to 3 minutes
• After powering on the miner for 3 minutes, press the reset button in your miner for 5 seconds then release
• The miner will restart its own automatically for 5 minutes
• Then monitor and check if the issue still persist

You can follow trouble shooting guide from bitmain if ever the issue not solve.

More likely you need to RMA this unit.


If you look here you can see that the software is detecting failed chips on your first board.

chain[5]: some chip cores are not opened FAILED!
Test Patten on chain[5]: FAILED!
chain[6]: All chip cores are opened OK!
Test Patten on chain[6]: FAILED!
chain[7]: All chip cores are opened OK!
Test Patten on chain[7]: OK!

Looking here we see that it is not able to query the hashing board for its temperature either, which is why there is no temp shown on the status page.

do read temp on Chain[5]
Chain[5] Chip[62] TempTypeID=55 middle offset=27
read failed, old value: Chain[5] Chip[62] local Temp=0
read failed on Chain[5] Chip[62] middle Temp old value:0
Done read temp on Chain[5]
do read temp on Chain[6]
Chain[6] Chip[62] TempTypeID=55 middle offset=26
Chain[6] Chip[62] local Temp=70
Chain[6] Chip[62] middle Temp=81
Done read temp on Chain[6]
do read temp on Chain[7]
Chain[7] Chip[62] TempTypeID=55 middle offset=27
Chain[7] Chip[62] local Temp=70
Chain[7] Chip[62] middle Temp=80
Done read temp on Chain[7]

How long will take take them to RMA it? And thera are no X or - on chips so i figured they are ok ?

I cant speak as to why its not showing bad chips, I just pointed out the errors the system itself is showing in the kernel log. If you are in the US you can ship to the California depot and from what I have heard recently its a 3-4 week turnaround

Ok thanks for the help.. I am trying to send it to hong kong for warrenty but I dont understand something.. It says on their website i have to print repair ticket and put it on the box, but in order to make a ticket i have to write tracking number.. I cant get tracking number before i send the package therefore I cannot put repair ticket on the box before sending the package.
Did i understand something wrong?

Hmm its seems to be working now.. after hard resting it few times and changing cables from psu

Hard resetting a few times solves a whole lot of antminer problems.
