Announcement: Bitmain launches AntMiner solution, 0.68 J/GH on chip

Delivery of 2 S3's from batch 2 today

I followed Dogie's setup guide here: https://bitcointalk.org/index.php?topic=702653


The 1st S3 miner works perfectly at around 440Ghs.

The 2nd S3 initially only started with 1 chain visible with a hash rate of 200Ghs.

I tried a few different CX750 power supplies but same result. Now the S3 starts but does not hash at all, a bleep and it restarts

For the time it is running I can still only see chain 1 visible but showing 0.0Ghs

Emailed and posted here, hoping Bitmain will resolve the issue.

I had the same issue with one of my S3's, it also had a single line for the blades on initial start-up.  I removed the cover, pushed all the connectors between the controller and blades into the sockets, then reconnected power and now both blades are showing and hash rate is fine (about 431 GH/s avg after 1d 21hr at stock settings).  I suspect workmanship issues with the cables, so I asked Bitmain to send a replacement cable with my next order on B4.
While you wait for a reply, you could try removing the cover (just a few screws, simple) and check out these cables.

Cheers

Thanks for the advice

I did remove the cover and check the cables when I only saw 1 chain. Everything looked fine, cables all pushed in and connected OK, the mining pools are all setup and alive but still nothing

I wondered about removing the cables from the controller and re-seating them but wasn't sure if this would invalidate any warranty?

I've had to put all the screws back on other deliveries of the S1's so thought this might be a case of cables etc. coming loose in transit.

I will wait for Bitmain to reply and see what they say.

I did the math and by my estimate batch 4 contained

2258

s3 units

I calculate Bitmain made 1468.7884731 BTC then divide it by .65 per s3 = 2258 units

I know!
I got stung AU$211 for 3x miners coming in, thats about a 15% markup.
I had no dramas with the S1s when they came in from the same location.
Anyhoo, the s3 units have arrived, and they are hashing away happily. Only issue so far is it seems the temp probe on one of the boards is a bit off, it shows ~26 degrees after operating for 30 mins. All the others, including the other on the same unit, show ~38 degrees.

neX:)

I got 2x miners on B1, so there was no customs/GST charge.  Beastlymac also reported that he had no customs charges. My understanding is that the GST threshold is AUD1000, something to consider in future purchases.
This time BITMAIN labeled the boxes 'Bitcoin miner', while on S1 deliveries it was 'computer gateway'.  Perhaps this labeling caused the long delays in shipping, as it 'did not compute' for the customs people.
I emailed UPS to ask why the delay and the response was that these are security checks outside their control.

Other forum members reported improvement after removal of the top covers from the hashing boards and cleaup of excess thermal paste (or adding thermal paste on chips that had none).  I'm not sure that this will fix your 'dead blade' issue, but you may have nothing to lose.  My theory is that the IDC (insulation displacement contacts) of the controller-to-hashing board cables is marginal on some of these, causing intermittent connection (not picked up during factory tests, but 'wiggled' out of connection during transport).

Good luck

Batch 4 sold out!

Batch 5 available... I finally managed to purchase 2 of these units!

Since i saw yesterday the Antminer S3 manual i am in doubt about pci-e connections.

In my S1 i used to conect each pce-i in each side of machine. I did the same with the S3. Its hashing ok but is it right or i must connect both 2pci-e just in one side of the machine and leave the other 2 in other side of machine free?
Thanks.

No, each board needs at least one pci-e connector, if you choose to use both connections on each board, make sure each board is powered from the same PSU 12volt rail if its a dual rail PSU, do not power a single board from different PSU's. BUT, each board can be powered by their own PSU.

[adqsonline]

Thanks, everything ok now, just powered them. I allways use 1 psu for each board and that was what i did. 1 conection only in each board, in this case from diferent psu.

I made a triple metal net case very thin to protect from the eventual dust.

Ok, this one is just for curiosity (and who know challenge bitmain to make some improvments, if already possible sorry for my ignorance in this matter). SOLO MINING WITH s1, S2 OR S3. in this case with S3:

1. I created a config file and put it in the proper folder at appdata,etc.
2. I created a bat file to work as server to put in the same folder of the wallet.
3. Then it requested me to put also a bat file in cgminer folder with connection instructions as username, pass, ip and port connection (this one i dont know how to do it as Antminer S3 already have cgminer).

So i tried to overpass the point 3 and put in my s3 the pool conection details after i click in server bat file but it crashes and in the antminer it says dead.

Any ideia how to solo mine with Antminer S3? Regardless is profitable or not. Just for curiosity.

Thank you.

The  figure  may be 2300-2400  since many had a .075 btc coupon.   

 Still 2300 x 440 = around 1 ph

batch 5 will be 2300-2400 more

Removed the covers and tried re-seating the cables. Same

Only chain #1 is displayed and hashing is at around 200ghs.

Still no reply from my email, forum post or twitter to Bitmain

Hi,

I've had 2 of my S3's now stuck in China customs for 4 days.....?!?!  Has anyone else experienced this long of a delay?  Anything I can do to move it along?

Thanks.

Some people reported a change when they moved the power PCI-e connections from the front to rear (or whatever you define as front on these Antminers).
How is your power connected?  (assume front is the side with the Ethernet connector).
Did you try to look under the covers over the hashing ASICS?

Where are you located? I am in Portugal, the boxes says outside Bitcoin Miner but i never had those costums issues.

It would be nice if Bitmain could change that for 'Computer Processor'. This expression fits in almost every fiscal system of any country. I know it because its my job to know it.

I am guessing sooner or later this issue could be getting worse as EEUU is already to plan to 'attack' bitcoin mining pools.

My S3 made it to Alaska in the normal time.

[kkurtmann]

ordered 3 b1 and 2 b2, got 1 unit 2 days ago and the other 4 today. easy setup, way way way quieter than my cointerra and spondoolies s10, hashing averaged between all machines for the entire day at 444 Gh/s each.

[pantgr]

hi all ,run one day my 2 new s3 no problem to report, also check the power constipation on 228 v ac get readings 2,8 A on both miners ruining,  322 w +-10% per miner . The HW error is all most nothing ,both miners run at 440gh and put the new firmware update also (antMiner_S320140721.bin).

thanks a lot bitmain
