you have a dead board.

try running braiins software and two boards.

I would tell you buy an epic controller from altairtech.io

https://altairtech.io/product/epic-umc/

but it is costly to do that. like $150

epic controller  will run 2 boards.


you could replace the control board to hashboard communication wire.

https://altairtech.io/product/antminer-ribbon-cable/

you could reseat the one not working. 


likely fix is either braiins and run two boards or epic and two boards.


a score is reseat the 18 pin ribbon and it works as that is free.

you have a dead board.

try running braiins software and two boards.

I would tell you buy an epic controller from altairtech.io

https://altairtech.io/product/epic-umc/

but it is costly to do that. like $150

epic controller  will run 2 boards.


you could replace the control board to hashboard communication wire.

https://altairtech.io/product/antminer-ribbon-cable/

you could reseat the one not working. 


likely fix is either braiins and run two boards or epic and two boards.


a score is reseat the 18 pin ribbon and it works as that is free.

Sir i’ve tried the HiveOs two of my boards are working(Hashing) the last one is still not finding the chips i guess..
I replaced control board with one of my other s19kpro even swapped the cables too.. but still the hashboard not working.
What kind of error is this In log i saw EEProm error still don’t understand.
Thanks for your reply sir

Since the first error said it's a mixed board then it's pointing to EEPROM and maybe the one hashboard is replaced. Did you buy it used unit?

Since you switch to another OS I don't think you still need to bother EEPROM error unless you want to stay using stock firmware? If you want to stay using the stock firmware you might need to use the hashboard code editor to fix that issue but it won't fix the other hashboard with 0 ASIC.
0 ASIC error is a hardware issue it needs to be replaced if you want to run the unit with 3 hashboard or like others do try to reflow all components on the broken hashboard with BGA hot air or put it on the oven but the chances to fix 0 ASIC issue is 50/50.

[philipma1957]

okay lets start from scratch.

You switched cables and no go. not a cable issue.

You put in a working bitmain controller and no go. not a bitmain controller issue.

So here is the issue the 1 board is dead is maybe

or the one board is mismatched and reads as dead. maybe


if it all worked fine for a while it is very likely the board died and is read as a mismatch.

bitmain firmware says fuck you all 3 run or we shut your ass down.

If you only want to run bitmain firmware if may mean you need to repair or reprogram the dead board.

But if you are willing to use after market products like braiins or epic both will allow you to run only 2 boards.

https://altairtech.io/product/epic-umc/.  the board is not cheap but you never pay a fee for it once you hook it up

look at my gear  all 3 boards are on. In your case you shut the dead on off and get 2 of 3 boards to work

Yes i bought this used from local market it was working fine from the past few weeks..
I have the chinese hashboard code editor can i give a try ?
The last part of your message is hard for me to understand can you please explain more i’m new to these miner thing .. Thanks for your time sir

[mikeywith]

You can try, what is the worst thing that can happen to a broken hashboard, however, unless you have messed the EEPROM before you bought the hashboard used, I don't see how flashing it would fix it, it's most likely a dead chip somewhere, which isn't going to be fixed on a code level, if you did the basic troubleshooting like swapping hashboard positions and still always get the same board then chances are it's just dead.

bitmain firmware says fuck you all 3 run or we shut your ass down.

Won't taking the dead board out of the miner solve this? since when did Bitmain start doing this stupid shit?

Well i will try the eeprom editor .. and i changed the position of the board still getting the error of that particular board and can you guys suggest me where to buy the single hashboard Online can’t find the hashboard for s19kpro ..
And i saw someone asking to put the hashboard in oven it may have solder Ball ?

I have had oem bitmain s19s refuse to run with 2 boards.

and run perfectly fine with braiins or epic.

braiins software is free to get and you pay a fee to use it,

epic controller is really good but costly to buy. No fees to use it. So if we get hot we save a lot in fees.
