Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order

[yslyung]

it magically comes & go at the same spot ! jeeez

"X" marks the spot ? i noticed few are seeing the magical "X"

well before bmt posts, my voltage is 12.4V on load ! so it ain't a PSU problem.

nope I am guessing this gear is simply less durable due to chip size of 14-16 nm

I think a lot of units are going to fail at a higher rate then any other bitmaintech product.

Symptoms seem to be happening with many miners in many places.

I suggest to down clock  a bit always keep temps at 65-95 as best you can.
Hope for the best with the gear.

makes no or little difference imo. agree on the chipsize though.

let's hope it does not spread ....

my prediction for next batches . . .

price is gonna go UP ! not expecting them to be cheaper .

you could be right   always a down clock on the august batch and it died in under a day.

I will be holding back for now on the s-9 and the r4.

I may get an avalon 7 or 2.

Meanwhile gpu mining seems to be saving me.

I may expand the gpus as the s-9's fail

It doesn't go away unless I reboot or apply changes from the configuration screen.
Then exactly one minute on the timer and it appears.

Mine aint a PSU problem either. It is running on a Jabber 4K setup from Finsky with 12.3 at the pci plugs going in the miner recept.

Phil, - I have dropped it back but I hate doing it. Warranty is not something I am not currently prepared to deal with mentally - even if it was covered. It has always been the worst company in warranty situations. I have been compensated in other ways well after, and I mention it because of full transparency and all of that.

Thanks for the comments and please let me know of any other ideas.

Gpu mine XMR AND ETH then convert to Btc.

I do not think these chips are going to be really durable.
So prepare for them to,die not so slowly.
This is all based on reports here and on my s-9s
No earlier gear has had this type of symptom.
My dead boards looked fine as did a lot of other s-9 board photos

Yep,looks like they saw the chumps coming & buying,so Bitmain cheaped up the design & parts list to squeeze you home miners even more & then hose who ever they can on the warranty & voilia, MO MONEY!!!!!!

Hi all,

Recently I bought some of the S9 B12 miners. They seems to be pretty unstable and some of the miners require restarting and rebooting.

The other problem I have is that on few miners only 2 out of 3 boards are beeing deteted, one board is not shown in the stats at all. I'm using Bitmain PSU and I tried replacing the PSU as well as rebooting the miner and updating the software. Does anyone has any solution to this problem ?

Also on one S9 there're not boards detected at all and in the Hardware Version it shows: "   Socket connect failed: Connection refused"

Thank you for your help

you were officially owned by bitmain.
think twice next time buying crap with 3 month "warranty"

To be fair  problems did not show for most people until two months in.

So if you purchased from June 1 to Aug 1   you did not know this gear would break easier then the older s-1 s-3 s- 5 s-7 broke.

If you buy after Aug 1 you kind of asked for it.

I had 5 machines running fine from June to August and I purchased a sixth on on August 9th  since then a lot of problems.

Hey all,
Can anyone recommend a good source for folks trying to fix an S9 hashboard. I've had some boards go bad and wanted to get an idea of the technical know-how required to troubleshoot a board. Any assistance or references to credible resources would be much appreciated.
Thanks all,
MM

If you're in warranty, contacting BITMAIN would be the logical first step. I think they've got some troubleshooting steps outlined in the manual. What problems you having?

[mountainminer333]

Hey Fusion,
The boards had X'd out and then upon reboot, would simply not show. For example, one of my S9's will only hash with 2 boards instead of 3 and the hashrate is around 8.6th. I've sent some boards back to Bitmain already (under warranty), but given the wait time and high international shipping costs, I was looking to fix it myself. I'm familiar with the troubleshooting process, but wanted to know about actually fixing a board.
Thanks,
MM

Gotcha, well i've never done that, dont plan to, so i cant be of much help. From what i understand, IF they can, they'll re-attach heatsinks and remove\resolder chips. Thats about all that i know, best of luck to you!

[not.you]

So what is the deal with posting images? I am unable to all of a sudden.




Why does this machine say it found a block?

recently I bought 7 s9. 5 of them are working fine, one of them is hashing is only on two boards caus I'm getting only 8THs and the other one is configured properly but it kind of restarting itself, the interesting thing is I have no time outs during pings when I can't log in into second one. And whats the max temperature of PCB and chips to run on ?

[mamiakimo]

i get message today that my board repaired and sent to me, but ..
yesterday i get my miner stopped and after restarting i found one board from the both still i have get temp higher then the other by 10C
and getting many HW errors 0.0023%
from 2 days the highest HW i get is 0.0003
i down clocked my miner from 550 to 529 ( its B9-600 Freq)
now one board have 87C and the other have 97C
can i under clock one board only ?

[MyRig]

Are you hashing with 2 hash PCB in the case instead of all 3?

yes, in a room with air condition and down rated from 600 to 529
is that wrong ?

I believe he is pointing out that if the missing board is not the middle (in other words one of the side boards) then the air flow in the cabinet would very likely account for one board running a lot hotter than the other.  One board would have lots of space on one side of it for air flow and heat dissipation (the center board) and the other would not (because it has the center board close on one side and the cabinet close on the other).  So the air flow differences from the missing board could account for the heat difference.

exactly what happen after removing third board so i decreased frequency a lot to make its temp in acceptable range
but after a week i suddenly get 10X more HW than what i get from it in the past

[mamiakimo]

here is picture from 3 days before what happen to the middle board ( on 550 Freq)
after 3 days and half i get 0.0001% Hw errors
now i get no lower than 0.0023%


i think i can't restore this board to the old situation
i tried restart or close the miners for hours
still have same HW error

[NotFuzzyWarm]

now i get no lower than 0.0023%

Ja that is more than you were originally seeing and is puzzlement why, but -- still perfectly acceptable and I'd say is fine. My s9's range from 0.0002% up to around 0.003% after a few days/weeks of running. 3 of them are running stock speed, 4 are slightly under clocked to keep chip temps below 100C.

Start pushing 0.005 and then I'd start poking around.
