ANTMINER S3+ Discussion and Support Thread

Yes, this is better.  Before it barely got up to 435GH/s with the low hashing board on the right side when looking at the RJ45 connector end.  The right side is the top chain and generally has the higher temperature and faster fan.  In this case it had lower temperature and slower fan than the lower chain.  So, taking the end plates and their fans, swapping ends and moving the controller board, put it back the way it was shipped, the questionable board on the cooler side.  

Almost right away the average went above 441GH/s and has remained above 440GH/s for the last 3h 23m and is presently 442.04 tho the utility is only 15.  No hardware errors in that time.  It was started as the afternoon cooled.  It remains to be seen what happens tonight as the humidity increases.

Oh well.  A minor improvement over yesterday morning and there's even greater humidity as it rained.  This morning the problem S3 is hashing at 434.15GH/s.  A nice improvement over finding it down at 419GH/s in the AM.  Guess I'll just have to settle with this hashrate.  The good S3 immediately next to it is at 440.85.


...1½ hrs after running /etc/init.d/cgminer stop, it restarts automatically after a minute or two, the hashrate of the problem is up to 442.18GH/s(avg).  It restarts with a fresh Elapsed duration.  So, I'll schedule this to run middle of the night and again in the AM.

Okay, I see this problem has been address in message #482 this forum with cgminer-avg-monitor script.  Kudos.

Okay, have written/modified the scripts and changed scheduled tasks.  By the time I was done the hashrate was down to 435.09GH/s  So, in about 22 minutes the script will run and it should restart leaving a record in /usr/bin/avg.log.  Nah, will try running from the command line...failed, typing errors I presume.

Okay, the lower case L was actually a one.  Runs fine.

darn, restarted with an x at position 8 of the 16 representing the problem board.

Sorry I don't mean to seem lazy, but I have looked and can't find it. Can someone kindly post where the instructions are to set the frequency setting above/outside what is listed on the drop down menu using the new firmware?

I know some of you have had decent results with frequency settings above 250. ie. 262.5.

Would like to give it a shot.

Thanks!

Miner Configuration, you'll see a gray'd out Advanced Setting to the right of General Settings.

A cold reboot with the machine off a minute allowed it to wake to 441.05GH/s and the x gone.  An x in the 8 position can only be in the center of the board if upper left ASIC is 1, lower far left ASIC is 2, second upper left ASIC is 3, etc.  This would put the eighth position of the chain at the center left bottom ASIC.  Next time I take it one apart I'll look at the component numbering and finding a component common to each ASIC, see how they progress.  Who knows, the ASICs themselves might be numbered.

Up 11 minutes and there's an x in a different position, now in the #2 position of the top chain.

[Stratobitz]

Does an x mean that the chip has shut down?  Or is it burning up?

Does an x mean that the chip has shut down?  Or is it burning up?

Likely means that it's completely shut down.  Not sure what the "-" means as a comparison.  I've found that completely turning off the miner and letting it cool generally gets an x to revert to an o.

Just rebooting works for me..

Just tried that and an x was changed to a -.  Wonder if they ever change to an o without a reboot or restart.

...the auto reboot for low hashrate by cgminer-avg-monitor at the half hour didn't clear the -.

weird, then try and shut them off for a while. If the "-" still appears, you've gotta do an RMA... But I think Bitmain will just send you a new chain board.

I know that 250 runs about 500 watts...and that three S3+s will cause a EVGA 1300 to shutdown.

 then that is a defective s-3+  my s-3+   that will run at freq 250 and keep the gh at 500gh use 390 watts on a platinum psu.


 I own a gold 1300 evga and it can run 3 at 243.75 no worries  1110 watts.

Since I only have 1 s-3 + that runs at 250/500gh I can not see if 3 will work on the evga.

 I suspect no.  as the evga ran  3-s-1's using 1215 watts   and doing 600 gh for about a month.  then did not want to continue at that clocking. I had to back off a bit.

yeah those numbers are a bit off... 250 should net u 505gh/s of course this is what a non overheating unit does. 38c/40c averages.
I highly doubt its drawing 500watts as my 750's are no hotter than the ones running some s1's
243.75 gets me 492gh/s on the ones that wont do 250

[MissouriMiner]

Just got my first two S3s. They're both running at about 455 GH out of the box, but GH.io is showing that one of them is sending about 200,000 duplicate shares per hour. Anybody ever see this before and know how to fix?

I think if you set the worker stratum difficulty to 256 on GHASH.IO Workers page, it will fix this.  256 works great for all of my S3's.  None have duplicates, and also the stale count is very low.

[bspurloc]

I have 2 s1's that after a few hours ALL the chips go to X. they are both overclocked and their hashrate stays at 200gh/s so I just leave them alone. They been like that for a few months. So I have to assume its a software glitch.

1 is at 10days 31k HW's which is extremely low. 216 rejected 6 stale.
other is 10days 114k HW 536 rejected 1 stale 
114k is very low also.

Is it  possible to run the s3 with 3G ? simcard + x (simstick , router Switch, Adapter?) + netbook = ?

A router and an internet connection is all that's needed for the S3 to run. However, you'll need to use your laptop to configure the IP address and pool information though.

Need help here. Anyone running multiple S3s on the same circuit, and if so, what are you powering them with? I have 6 of the new batch 8 S3's, and they are all on the same circuit. Running two pairs with a Corsair CX750M each and the other two with an EVGA bronze 1300W. Thought this would work well, and they mine perfectly, but the one outlet in the room that isn't being used for anything is warm to the touch. This obviously isn't good. I was a noob before this running two overclocked S1s with one Corsair CX750M and have apparently bit off more than I can chew.

Any help from one of you vets would be highly appreciated 

[mindtrip]

easy solution your overloading the circuit probably do to poor wiring in your house I would move one of those power supplies to a separate circuit right away to avoid a fire!!!

[bennynjetz]

Thanks, mindtrip. Obvious answer to a stupid question

[moss]

l took your advice and ordered the Thermalright TR-TY143...  Just out of interest I'd like to add that I think discussions about temperatures on this forum are a little over-hyped. 50C is a perfectly acceptable temperature for an asic to run at. Note that the menu shutdown temperature default is 80C. I worked for a computer manufacuturer and regularly changed ic's using hot-air guns where temperaturers attained hundreds of degrees C during the process and it never caused problems. You'd be surprised how much abuse ics can take. It's over-voltage kills them, not overheating.

Hi mate, I take your point, but I think you've done the right thing.  The asics in the S3s seem to be rather temperamental and someone posted a while back how just running without the case fitted was enough to 'x' out an asic that was distant from the inlet fan.

Need to know what amp circuit the room is using.  A 15A circuit has a max of 1800 watts, but you should probably keep it under 1440 watts.  A 20A circuit has a max of 2400 watts, which is what I have, and they say to keep below 1920 watts, but I'm running a little over 2000 watts.  (80% of max for continuous load.)   You could have the wrong grade of wiring.  A lower grade wire will get hot, and could even cause a fire if not up to specifications.  For example, if wire that was rated for a 15A circuit was used with a 20A circuit.  Even with 2000 watts, my outlets are not hot to the touch, and barely warm.

Your welcome not to get into a lot of detail but usually outlets are all linked together on a circuit so if your wiring gauge is incorrect or an outlet is not wired correctly it can cause a high load at a particular point in the line in your case that hot outlet is probably in between the outlet your using and the breaker. If the wiring is old this is a concern. I personally ran new dedicated 20 AMP Circuits for all my mining locations to ensure 1> Correct gauge wire and outlets were used 2> nothing else i wasn't aware of was on that circuit 3> Peace of mind
