Antminer S9 13.5T

[SkaWeasel]

Hi guys,

I have 2 antminers S9 13.5T, I updated the firmware of those machines and I noticed they started to fail. Currently they one miner only detect 2 hashing boards but the third HB works, and the other one detect 3 HB but one it's not hashing.

I investigate a lot, I have made a lot of tests and I couldn't find any phisical damage.

I was wondering if someone has that version of Antminer, without firmware update, can you please share a backup of your firmare??? This because I started to think this is a S.O issue not a hardware issue.

Please help!!
Thanks guys.

First things first, what psu are you using?

Hi,

thanks for your reply.
Im usign the bitmain official PSU, I bought it together, from Bitmain.com

Also I have 5 PSU all from bitmain, and I did try to change to check if it was the PSU but it's not, because I have L3 miners and they work just fine with the same PSU.

220VAC input or 110VAC input?  L3 only pulls 800W, while the S9 will want more power than the Bitmain PSU can deliver on 110VAC.

Sorry, all runs with 220 including my L3

Ah, then probably not a psu issue.  You might just have a wonky board unfortunately...

Make sure that you are not going over the capacity of the delivering equipment. Someone here said that they had the same problem and it turned out they were capping the capacity of the transformer.

Hi all,

thanks for your replies.

Actually I thougt it was the electricity but I discconected everything and just put one S9 to work and it behave the same way.

and other very strange thing it's that all my miners stop working correctly at the same week.... thats very odd

If someone has that version of antminer S9 13.5T without firmware update, can please backup your firmware and share a copy, just to make sure the firmware it's working propertly. Because I did test everything except that..

thanks

Just go on bitmains site and grab older firmware, you dont need someone to back it up for you.

Stay away from the Nov 17th firmware, it has been confirmed that this version has a ton of problems.

Hi,

I did, but I think that causes the issue, so that's why I want the original firmaware without updates...

It's just for testing because I have tried everything so far except this...

Thanks

There is no "original" firmware. The miners ship with whatever is most current firmware available, sometimes the default firmware is so new they havent publicly released it.

I see, so I guess I'm f**k whit those 3 miners...

 

I guess I need to send those to bitmain for repair..

Thanks guys!
