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.

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 ?

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?

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!

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?

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.

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!!!!!!

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 chip size 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

I had 2 ship on June 12th they will be off warranty on Sept 12th > one dead board after 70 days
I had 2 ship on June 21st they will be off warranty on Sept 21st
I had 1 ship on June 27th it will be off warranty on Sept 27th
I had 1 ship on Aug 17th it will be off warranty on Nov 17th >>>> this had a dead board in under 10 hours

This gear could be very painful if it continues to fail for lots of us.

So I get the dreaded x.
In the past this has lead to a failed hash board.
This is a B1 unit. The default freq is 650. It is possible this started a few weeks or so back. I know it wasn't there when I installed or shortly after.
I have changed the freq all the way down to 500 in increments of 50 with the same results.
The odd thing is something I think I learned from the sidehack thread regarding the way Bitmain has the voltage sent after it boots and does a couple of other things.
I get the x at exactly one minute displayed on the status screen timer.
Or maybe it is a cold solder joint, bad ASIC, or loose connection. That is why I am asking for input from the best minds in the game regarding the options.
I guess the ASIC # does not mean the current number of running ASICs?

I have also ran it in slightly cooler and much cooler temperatures.

Any opinions are appreciated.

Have you tried plugging the ribbon cable into a different socket on the controller?
