Wanted to share my experience so far.

Ordered and received an S2 on 4/29, received it very quickly, boards were loose but nothing damaged OR bent on the inside.  

Ordered another one on 5/20 and was set up to receive it on the 27th.  I didn't. I called UPS, they said it was in customs in CA but they didn't know why.  I received another call later that day, the 28th, from UPS saying that they needed to investigate the package and would reply via email once it clears customs.  I received no email or other communication from them.  

I got it less than 24 hours later and here's what arrived:

There are no scratches or dents anywhere on the case.

Inside:




Radial caps disconnected (presumably from being smacked by loose boards):


SMD caps detached from the board:


So I soldered the caps back to the backplace and fixed the bent braces.  Even the board with the missing capacitors seems to be okay.  Are there any negative long term effects that could happen by using that board?

After surgery it is happy and hashing:


I have to stress, the case was flawless, not a dent or scratch on it.  I was missing the 2 side screws, which I thought was slightly odd.  I just can't fathom how the braces on the side get bent like that during shipping without some damage to the outside.  The cable that connects the controller board to the lcd screen was also disconnected from the lcd screen, not the controller board.  One of the pci connectors on the psu side of the backplane was also disconnected.

How on Earth does damage like that (the braces) occur without any exterior damage?    

Please understand, this post wasn't mean to disparage BITMAIN, nor was it meant to discourage people from buying Antminers.  The unit I received today is currently hashing better than by first batch 4 unit.  I will likely be purchasing the coming "upgrade" package as well.

Happy hashing!

He paid for goods and they were damaged - it's normal to complain about that is it not? Albeit his miner mines so I see what you mean...

I care because i  factor resale into my ..ahem... "profit" happy to swap...cases

Seriously, why do you care? I have a miner that looks perfect, but only 9 out of 10 boards hash. Do you want to exchange? LOL

I ordered Sat, delivered wednesday to UK... not bad.

 Has anyone approached bitmain re damaged cases? i have two folded corners and a dent in the top.

......@bitmain ( shouts into the dark ) "Any replacement cases sent out?"

Looking forward to your photo !

The coupons seem to expire Shenzen time.
All my S1 coupons and most of my S2 coupons expired mid-day yesterday. And I expect my remaining 2 S2 coupons to expire "anytime now".

S2 received yesterday after ordering it on Friday evening.  The boards inside were all jiggled loose during shipment and the case itself was a little bent but everything works fine.  I wonder if Bitmain could consider shipping the boards secured together seperate from the case itself so there is less chance of damage from the boards clashing around in the case.

Everything works though after plugging them back in.

I dont think anyone has any s1 coupon that doesnt expire 29/5

I have ten (10) S2 coupons to give away, all of which expire tomorrow May 30.  PM me your bitmain ID and let me if you want one or more of them.

I am looking for S1 coupons (4 would be great).  Does anyone still have any and willing to part with?

Question @BITMAIN Any more info on the upgrades you will be offering? Technical details? possible Pricing?  It would be nice to know what is coming. Thanks

this is strange, I have not seen this. In fact, my second pool earned just 0.00009 BTC in several months on multiple miners, which also means that third would have earned essentially nothing.

bitmain DON'T do REFUND.
You are warned!

Then use a proper version of cgminer
https://github.com/kanoi/cgminer-binaries/tree/master/AntS1

P.S. it doesn't do what you described in any version.
The list of pools is passed to cgminer at startup.

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.

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

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.

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.

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.

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.
