someone in bitmain support i beat him before
now all my tickets that assign to any one else they transfer it to him and he replied to me after 1 week and say anything not related to what i am asked for
what should i do ?
|
|
|
|
|
i have 2 boards went to repair from one machine under warranty ( worked for 1 month )
and they told me one board is scraped
every time i send message to ticket i get answer after 7 days or more
they are the worst technical support I've ever dealt with
|

I understand that you are a fan of all things BMT, but what makes you to be an expert on S9?  1) I'm not a "fan". 2) Experience with ~1,000 units? 1% number could be accurate with regards to recent batches of autotuning 13.5Th machines, but initial batches (last summer, not autotuning) had up to 10% (or even a bit higher) board failure rate (within first couple of months) according to multiple sources, which was amply documented here and elsewhere. Perhaps, most machines that you got were purchased during later part of 2016 or in 2017. In summary, we have a better S9 in modification (from 12TH to 14TH) which have reducing the failure rate each batch, do we? i have 3 machines from the earlier batches and i lost 5 boards from 9 1 of them sent for repair 2 times 2 of them sent for repair 3 times! after repairing it and return it take from 1 to 3 months to stop hashing again now i have one board on the way to then for the 4 time and i have one with them it stopped after 3 days from repair and sent again under warranty to china ( the paid for shipping ) i have 6 autotune machine + 2 R4 and not lost a single board i have room with digital control to make temp not exceeded 30C so temp on my room between 18 to 30C |

Sorry to hear that.
Have they said what the damage is? I can think of many things such as blown internal traces, lifted pad, etc.
Again, this is why Bitmain Warranty (and Bitmain factory service) need to provide a report that says more than 'Fixed" or "Unrepairable"...
no they just told me it cannot fix so i paid 300$ for 8 hours of hashing with 4.6TH |
|
|
|
they told me to send it to them for repair
and today they told me it's damaged and unfixable
It's fastest 300$ i lost in my entire life
where did you send it? China? or Colorado, USA I just got a bill for mine which I sent to Colorado 25 to ship to them 175 to repair 25 to ship back = 225 cost. I am in New Jersey. They did give me some mining for the 1 board about 50 bucks but could have been more if they did 1 send of btc with 1 fee for 0.0002 instead of 4 smaller payments and 4 tx id payments of 0.0002 all in all an okay experience . Since I did not send to China USA |

Ya if you have had that much bad luck with the same board in the same miner you should start trying to narrow down the cause of the problem and start looking at your power supplys as well as all the wires and plugs going to the board in ? that keeps dieing on you. esp now that they have had to of been plugged in and unplugged a few times now just from dealing with the board issue so many times. PCI-e female plugs are only rated for a maximum life of 30 cycles of plugging them in and unplugging them before failure even in the best conditions. They really are not meant to be unplugged more then a few times in their life before they need to be repined. and really not even meant to be pushing as much amps as they do when used in something as power hungry as an s9
and if its not a power supply issue or plug and wireing issue I would start looking at things such as the fan or what sort of temps the air intake air is at where ever you are running the miner that keeps haveing a board die on you over and over.
Or you could just have really really bad luck. Which can happen.
before i get the board i moved this machine to new apartment that have more good air flow because we are on summer now and changed the PSU too from EVGA 1600G2 to APW3 which i get it from one month from bitmain ( i have only one APW3 ) when this board stopped hashing i tested it on another data cable and start the machine with it only but it still not working |
|

|
i think problem is from your psu, i have 3 s9 but all of them are working fine for me
its better that you chenge your psu
another possibility is from power oscillation
before i connect the new board i changed the place of this machine to another apartment and i connect it to APW3 the evga 1600G2 that used with it before is used now with another machine with no issues |
|
|
|
pretty bad luck. are you sure your PSUs are OK?
EVGA 1600 G2 for 5 months then replaced to APW3 |

hi,
i have 7 S9 and 2 R4
all of them working fine except first one S9 Batch 9
after 2 weeks from getting it i lost one board and they repaired it under warranty
after 2 months it stopped hashing again ( same board )
they told me it out of warranty so i send it to paid repair
after i get it and install it the all machine stopped working!
after reset i found the 3 boards stopped!!
i told them and they told me to send the 3 boards to free repair and they will cover the shipment cost
after 2 months one of them stopped again!
i send it to repair but they told me it damaged and cannot be repair or replace because it out of warranty
i told them to give me new board but they told me to purchase anew one from bitmainwarranty
i send message to bitmainwarranty to purchase a new board
i get answer from Ashli told me it will cost 175$ + 25$ for shipping
i paid using BTC
and after that he told me that he told me wrong price and the correct price is 550$
i told him to recover my BTC and i don't need this board
he told me ( My apologies I will go ahead and just ship the order to you. )
after i get my new board and installed it by 8 horus it stopped hashing!
i send bitmainwarranty a message from 2 days and i don't get response until now

after shipping your miner back take screen shot for FedEx bill and drop it on you support ticket they will give you a coupon with the same price of shipping
and they will ship your package back for free
