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

[Biodom]

If you've got one S9 hooked upto the APW3 PSU then if you unplug the PSU from the wall then it will stop mining and switch off. Possibly run for a second or two once power is off as the capacitors will have to discharge.

just don't touch that plug with your hand after you disconnected or you will get a fine memory...not.

Two 11.85th boards arrived today. Will crank them up later.

so, so far what is your % of boards that went bad?

Very good point I should have mentioned that. Some things are common sense to me, but sometimes I must remember everyone hasn't quite got the same sense

Hey team,

I noticed my S9 today (for a few hours) experienced a drop in hashrate for 1 board. It went from a typical 4600 GH/s down to 1250 for about 3 hours until I noticed. There were no xxx or anything. I restarted the miner and it is hashing like normal again. I will continue to monitor. I've had the miner for about 2 weeks.

Should I be concerned? Do you think the hashboard would have recovered on it's own eventually? Do you think it would have been bad to continue without restarting?

Thanks

I would guess that the temperature of the chips dipped too low. It is a common problem for the S7 as well. You will not usually see any Xs when it happens either.

You may be right the ambient temp in my garage is 4 deg C at the moment. I am working to increase the ambient temperature.

Cheers

I wonder if you could redirect some of the heat output back into the input.

Good idea man! This is what I ended up doing, I put my S9 on a shelf and enclosed it in a bed sheet. Much of the airflow is returned to the intake, and much is replaced with fresh cold air. Simple and cheap

i just don't see a on/ off switch on the BITMAIN APW3-12-1600-B2....what do i do ?

It just occurred to me that you did not even connect a power strip to the wall before connecting your APW3 to it.
A good power strip has an on/off switch, which you can use.
Using high power power supplies connected to expensive equipment without an adequate power strip (or PDU) is a good way to get your equipment ruined if there is a lightning nearby. I use APC:

not sure if it is enough, but was OK so far when lightning shutdown everything on multiple occasions.
It also has an electrical noise filtering (EMI/RFI) and would indicate a faulty circuit.

Not sure, pretty low. 90 boards, 4 bad after a while. 2 warranty, 2 not.
Have batch ones and up.
They are not as reliable as s7's were.
But they use a POOPload less power.

Perfect, I was going to say put in a cardboard box with adjustable hole on top.
Bedsheet provides pretty good insulation, heat containment.

Looks like they are confiscating gold from India's people. Jewelry also.

I had a S9 mining at around 5.6TH, so decided I'd try the newest firmware.
Now I get this:
Hardware Version   Socket connect failed: Connection refused
Kernel Version   Linux 3.10.31-ltsi-00003-gcf03eb9 #81 SMP Mon Apr 25 11:20:36 CST 2016
File System Version   Tue Nov 29 06:13:15 EST 2016
BMminer Version   
Uptime   1
Load Average   0.13, 0.04, 0.01

Tried power reset, leaving it unplugged, everything I could think of.
What should I do?

And to balance that with the Official stance:

It is Gold from undisclosed income they are after.

New "self tuning" firmware takes up to 20minutes to start mining after a reboot, during which time it gives that error. Try leaving it running for half an hour and see if its ok.

Also check what batch of miner it was, some firmware is only for the later batches.

A screenshot of the 5th running would be helpful.
It takes 7  minutes to boot on the new firmware for me.
Is this a 11.85th or 12.93th? 12th seems to work but 11th not as much. Better to keep the original firmware on older s9's
Sounds like one board dead one board running and one board running crippled (just a few chips running)
New firmware won't help 5.6th
Sounds like 2 boards need repair.
Without screenshot cannot be sure.

Apparently, Bitmain stocked 12.5Th miners for Hashnest at $1699 a pop.
I don't remember such setting in the batches that they sold, or was it there?
I remember seeing 14, 12.93, 11.85, 11.
Maybe 12.5 is something new, but it would be grossly overpriced at $1699 considering that they were selling 11th for $1232 a couple of weeks ago.

[PeaMine]

You were right, just takes much longer than I expected to boot up fully.
Though on the new autoset firmware, even 20 minutes still didn't connect.
Rolled back for now.

Still at 5.6th?

I have a batch 23 S9.

What should I expect the board temperatures to read? The miner status page reads 87, 84 and 101. One board is consistently hotter. Any concerns?

The board temps seem to change if I power down and restart, where other boards become consistently hotter / colder and generally stay that way until the next time I power cycle. Seems like odd behavior to me, but I assume it has something to do with the firmware.

Also is there an ideal temperature for hashrate or for long life?

Thx

strange behaviour.
why they do not spread the news this time?

Temps look perfectly normal.
With the auto-tune firmware Bitmain has used since batch-16 there is nothing we as users can do anymore to change hashrate or temps.

And no mention of Batch number. How very weird. Even the s2's had batch numbers, wonder why the change?
