Title: Antminer S9 13.5T Post by: SkaWeasel on April 16, 2018, 02:35:13 PM 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.

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. Regards Title: Re: Antminer S9 13.5T Post by: VRobb on April 16, 2018, 09:08:46 PM 220VAC input or 110VAC input? L3 only pulls 800W, while the S9 will want more power than the Bitmain PSU can deliver on 110VAC.

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 Title: Re: Antminer S9 13.5T Post by: fanatic26 on April 17, 2018, 09:09:47 PM 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. Title: Re: Antminer S9 13.5T Post by: SkaWeasel on April 18, 2018, 01:59:23 PM 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 Title: Re: Antminer S9 13.5T Post by: fanatic26 on April 18, 2018, 04:41:30 PM Hi, I did, but I think that causes the issue, so that's why I want the original firmaware without updates...

The miners ship with whatever is most current firmware available, sometimes the default firmware is so new they havent publicly released it. Title: Re: Antminer S9 13.5T Post by: SkaWeasel on April 18, 2018, 04:47:48 PM 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! |
