Topic: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order - page 221. (Read 531173 times)

the socket connection error will show up until the miner starts hashing away. if you havent upgraded your firmware the auto tune feature can take the better part of an hour to complete so you might see that error for a long while....if its been more than an hour something is wrong.

They keep releasing new firmware almost every day?  
I tried the October 25 one in my S9, batch 2 because it has problems reaching the nominal 12.93Th/s hash rate.
The update was no good for my miner.
I usually need dosens of restarts with the miner to reach the nominal hash rate.

Typical Chinese customer service, they find a new bug that is in the firmware, and then will work on it. The next release, the same bug will still be there, and they will work to fix it.... and on and on. Now who thinks that they have an internal firmware for their machines to run better. 

AFAIK, the socket connection error refers to a Virtual data port/connection setup between Linux/CG or BM miner/ and the hash boards themselves. Because the hash boards are busy and not taking calls right now, the full connection to the GUI cannot be setup.

The OS/miner firmware will keep trying to talk to the boards. Before the auto0tune update it normally took maybe 30-45 sec for first (warmup) connection, followed by a restart at normal settings.

After auto-tune... 'whole new ballgame as to when the connection can be made. It (a good Socket connection) comes and goes each time a board is tested before things settle down...

I've wondered the same thing. All firmware I have tried suffered from this problem.

what causes this "socket connect failed..."?

Is there a firmware to get rid of this?

No autotune for me on old releases. I am currently testing the new release, I'll let you know if anything changes.

I am curious if any of these newer autotune firmwares have actually worked to autotune the older model miners.  So far from all of the posts I have seen, installing the new firmwares on older miners does not actually get them to autotune at all.

You might want to "open" up the file and see what's inside. I don't mean try and install it, but within a file named like .tar.gz there can actually be multiple files. While it might be a stretch to hope for, many companies will include a TXT with info about what's changed and possible installation info.

You can't count on Bitmain to do that, but it won't hurt to look inside.

If you are a Windows centric person, 7-Zip can help out.

Looks like another day, another build.  Antminer-S9-all-201610250334-autofreq-user.tar.gz

Any idea what's in this one?

that would be true if i paid for power and if i were using a typical home ac unit. the units i have in each room are industrial roof mounted chillers. they do bio research here so the labs have to be very cold so since they are running all of the time the building manager diverts some of the cold air into each of the rooms i use ontop of the dedicated ac unit for each of the rooms so i get double the cooling and also if one were to have issues the other is there to pick up the slack until the first is repaired. better safe than sorry i suppose.


its getting cold here at nights though so i started running some of the s7's i upgraded at lower clock speeds with fan filters (home mining it dusty. the ac units in the offices do all the air filtration so those miners dont need filters on them because they dont get dusty ever) an use them as space heaters for my bedroom and the basement and so on. they work quite well for keeping rooms warm and will offset my electricity bill for sure. i used to run a 1500w IR space heater in my bedroom which would run alot and wasted tons of power. now i run my s7 and use 700w and i make some btc on the side while doing it.

as for overclocking the s9's....if you have an older version of the s9 you can but like others said its risky and not really worth it. you may be able to squeeze a few extra gh/s out of the miner but is it really worth risking your miner for a few gigs?? i sure dont think so lol. with the new version of s9 it auto clocks itself so you cant set the speed of anything manually like you could before. one thing that is interesting is that by clocking itself to whatever speeds you can see which boards are the top performing ones and if your into this sorta thing you can take the good boards and combine them into 1 single miner that runs very well instead of 1 miner having 1-2 good boards and another miner having 1 good board and so on but it might be best to not consolidate them.

If you have a 650 batch then you probably could. I have a 600 batch miner running at 606 without a problem. Just keep in mind that the S9's in general are known for a high failure rate so you are taking a bit of a risk.

1. Remember that you are voiding the warranty
2. There could be some stability issues
3. If you are in safe zone temperature wise and don't have to worry about the warranty any more, go ahead carefully.

Anyone tried to overclock this one above 650? I have mine running very cool so was thinking if it would stand a little overclocking. What do you think?

It's here already:

they are probably selling it to a large buyer, like viabtc, so, who knows.
It is overpriced anyway.

Someone have a real experience? How long need to wait for return of buying price?

i hope someone send my this versions
