ANTMINER S2 Discussion and Support Thread

[dogie]

Thought I'd post an update on my unit, been rock solid. As always if anyone has technical problems, please post in the help thread.

I have lots and lots of S1 and S2 coupons available.  Contact me ASAP if you want one or more because the S1 coupons expire May 29 and the S2 coupons expire May 30.  Just PM me your Bitmain ID and let me know how many you want of each.

They are free for the taking, although tips are appreciated:

Well, look what turned up in one of the S2's I ordered today!



I'll open it up tomorrow and get a photo of it.

This was in dmesg, for anyone who's interested

^^^ Interesting! What's your total hashrate?

[edgar]

just a heads up - its only been 36 hrs but swapping the 4Gb class 4 SD for an 8Gb class 10 seems to have stopped the daily beepings.


so yea, saving a dollar per rig on cheaper SD cards causes miners to suffer untold downtime - must be worth it.

[klondike_bar]

i upgraded to a 2000W and overclocked to 1100GH

What frequency setting for 1100 ?

Im running 215.625MHz (any higher was >1% errors) and the S2 says 1100GH average but pool says 1068GH average.

doing the math now, its current error rate is 1.06% so i may need to tune it down to 212.5MHz

Thanks. What are reported temps ?

A question: out of 3 tar files on bitmain site, do you need only the last (from 20140410) to put on backup SD or all three of them. Instructions are unclear to me.
Do I just put the tar file directly there or decompress it first?
What is the use of SD partition tool? Much obliged for any help.

No change. The Kernel is treating it as a 64 chip board (which is why I posted the dmesg output). I'm running with 0881 as the flags (225mhz) and it's hashing nicely at about 1100gh.

Had an S2 shipped on the 22nd, now it's sitting in customs in California.  UPS can't give me an estimate as to when it will be released.  Any US buyers run into this?  How long did your package take to clear?

Thanks,
Dave

this seems to be an ongoing issue with regards any mining equipment, i'm reading it all over the forum

Ontario, CA.....I went to Montclair High, though that was 35 years ago   

I had relatives that lived off of Euclid, just below Holt Blvd in Ontario.

I have over 20 S2 coupons that are about to expire on 5-30. Send me a PM with your bitmain userid, let me know how many you need, and they are yours for free.

[Biodom]

I've got an S2 with only 9 slots working. I know that it is the slot and not the board because i switched the boards around to no positive effect.
Anybody had the same?



Is this somehow fixable or a lost cause and I will have to endure a 90% miner. I will ask bitmain for some compensation. Was anything ever given in cases like this?

Where is LOGOUT on the web gui? I don't see it. It is too minimized in comparison with S1, in my opinion.

try putting one of your pools on line 3..  you only have two pools.  copy line one and have it on 1 and 3.


did you always try to run all 10 cards     or did you try   slot 1 and slot 2 only?   just run 2 cards   to see if slot 1 works.


your psu may be only able to run 9 cards and slot one is the one that gets the least power.

Thanks. interesting..., no, did not try to run just two cards-will try. re pools, i usually don't bother with a third pool. it never affected anything in a good way, but I certainly got some trouble when I specified btcguild as third at one point.

[edgar]

i found they want to failover to the 3rd pool at times - after removing the 3rd pool i have considerably less ppc income...

yeah on the s-1's  if you do 2 not three and the second one fails  there is a longer delay   as it goes to line 3 finds nothing  then goes back up to line 1. 

you can lose 5-10 minutes of mining   each time that happens.
