AntMiner S4 2TH/s for sales shipping before September 29th

Only Available at bitmaintech.com

Published on September 1st, 2014,





The enormously powerful and power efficient AntMiner S4 2TH/s is now available for sale globally.
The 1st Batch of AntMiner S4 is 1,450 USD per unit (excluding shipping), with dispatch estimated September 29th. Batch 1 will go on sale at 22:00pm Sept. 25th Beijing (UTC +8 Time Zone)

The AntMiner S4 is the fourth generation Bitcoin mining rig by Bitmain. It uses the state of the art BM1382 chip powered by the 28nm tech process with ultra-low power consumption.

Power efficiency progress is reflected from the S1 to the S4 and is our focus to improve your investment and save on electricity bills.


Update:  The typical conditions of BM1382 are indicated in below table. We were trying to share its best power efficiency, which is less than 0.5W/GH/s.
 

But it seems to be potentially misleading. so we have edited the graph.



The AntMiner S4 is built into 3U size box, although its hashrate is twice that of the S2. The S4’s design is hugely improved from S2’s experiences, using less hash blades and adjusting the space structure in each box to bring a light and portable model. It will be very convenient to deploy.

Specifications:
* Chip Operating Voltage: 0.72V
* Chip Quantity per unit: 160
* Hash Rate: 2,000GH/s guaranteed
* Power Efficiency: 0.69Watt/GH/s at the wall
* Over clocking: About 10%, but not guaranteed
* 3U Rack  432mm*442mm*133mm
* PSU inside: 1400W, 80PLUS gold. Power line not included. You may look for one line with no less than 16A in your local market
* Temperature: 40-50 degree Celsius tested in the mining farm
* Fan Speed: 3900RPM
* Stable but a little bit noisy
* Ethernet connection, Stand alone
* Certificate Compliance: FCC/CE



Notification for S2 Upgrade Kit - Coupons being issued

To all customers that ordered AntMiner S2s: We analysed the business case for S2 upgrade kits for end users and determined that it would not be worthwhile for either party.
* The S4 runs at 0.69 W/Gh/s power efficiency, which is significantly improved compared with the S2’s 1W/Gh/s. Even though the upgrade kits used the newest BM1382 chips manufactured at 28nm process, it was not a significant leap in power efficiency.
However, the next generation chip is more likely to be worth doing upgrade kits with.
* The S2 is still profitable to run for the next several months with its 1W/Gh/s power efficiency and so now is not a good time to replace them.

Coupons will be issued to express our sincere thank you for supporting Bitmain over the year. Each coupon has a value of $200 and will be issued for each S2 unit purchased. These coupons are only applicable for the purchase of S4s and only one coupon can be used per S4.
If you ordered an S2 on bitmaintech.com, please check the coupons automatically added to your account. If you ordered an S2 from our authorized partners, please contact them directly to get your coupons. Below is the list of the authorized partners:

FAQ and Technical Support

Power cables required:
USA Cable | UK Cable

Dogie's comprehensive setup guide now up in super HD!

Configuration
Quote
Wiring:
  • Plug in a power cable from the AntMiner to the mains
  • Plug in an ethernet cable from the AntMiner to you router.

Configuration:
  • Power on the power supply using its push button at the back.
  • Make sure that your router's subnet is 1, ie 192.168.1.x. If not then change it to 1, this is just temporary. ***If this is not possible, see below***
  • Using a browser, navigate to 192.168.1.99 - this goes to the S4's configuration page.
  • Login using "root" as both the username and password.
  • Navigate to Network -> Settings.
  • Change protocol to DHCP and click "Save & Apply".
  • Using a browser, navigate to your router and find the IP it has assigned the S4 and navigate to that IP. This IP will also be displayed on the LCD.
  • Navigate to the page Miner Configuration -> General Settings. Enter your pool information in the below format.
  • Select "Beeper ringing" to "false" and click "Save & Apply".
  • Navigate to the page "Miner Status" to check mining has started.
  • You can then change your router subnet back to whatever you are used to using.

Alternative Subnet Change:
  • Unplug your computer from all internet sources.
  • Plug in an ethernet cable from the AntMiner to your computer.
  • Navigate to Control Panel -> Network and Sharing Centre -> Change Adapter Settings.
  • Right click on your ethernet adapter -> Properties.
  • Click on "Internet Protocol Version 4" and click properties.
  • Select "Use the following IP address" and enter the following:
  • IP Address: 192.168.1.1, Subnet Mask: 255.255.255.0, Default Gateway: 192.168.1.99.
  • Plug in an ethernet cable from the AntMiner to you router.
  • Restart the configuration instructions as above.

***There is currently a firmware issue that prevents the S4 achieving its full hash rate on pools with variable difficulty.
Until a new firmware is issued, its recommended that you use BTCGuild or GHash IO with 2048 difficulty manually set***


FAQ
Quote
ProblemSolution
"x".in.a.row.on.miner.configuration.page- There is a faulty chip - nothing we can do. Hash rate will be affected by ~3%.
Almost all "x" on one row of "Chips"- A hashing board may be mispowered or faulty. Recheck your cabling and PSU.
How do I change the login password?- Navigate to System -> Administration. Enter the current password and enter your new one twice.
What is the SSH login?- Username is "root", password is "admin".
Can I turn the beeping off when the miner stops mining?- Yes. Navigate to Miner configuration and turn "Beeper Ringing" to false.
I can connect to the AntMiner but its not hashing?- Set the protocol to DHCP via Navigate to Network -> Interfaces -> WAN -> Edit. If you
don't want to use DHCP, navigate to Network -> Settings and make sure "Gateway" is set to the
IP of your router.
What temperatures should I aim for?- Try and achieve <60 for best hash rates, and <70 for long lifetimes. Temperatures should not be
 let to rise above 80C.
Where can I get the latest firmware?- Download from Bitmain's Github.
How can I tell what firmware version I have now?- Navigate to System -> Overview and look at "File System Version".
How do I install the latest firmware?- Download firmware as above. Navigate to System -> Upgrade and click "browse". Select the
downloaded file and click "Flash image". Do NOT interrupt this process or you will brick the unit.
How do I reset settings to default?- Once the unit has been on for a few minutes, use a paperclip to press the reset button for
5-10 seconds. It is located in the bottom left hole on the LCD. The miner will then reset with
stock settings.

SD card image if you need it.

Hello all,

Bitmain has employed me to help liaise with the community and later provide technical support. They have done this in order to help provide:

1) timely technical support
2) provide better feedback (if I don't know, I can find out from the people within Bitmain who will)
3) provide product and sales input from you guys directly into the company. If something is going wrong, YOU can fix it
4) provide native English press releases - less ManderEnglish, more sense.

This is a paid position, however it will in no way affect my independence or freedom in being critical towards Bitmain outside of this thread. My contract specifically stipulates:

Quote
Dogie will speak on behalf of BITMAIN and will not criticize BITMAIN in these threads. Dogie still reserves the right to criticize BITMAIN in his other threads. Both parties acknowledge that this relationship has no impact whatsoever on BITMAIN’s rating or standing in “Dogie’s ‘Manufacturer Trustworthiness” thread.

This means I won't sit here and reply to every post saying Bitmain is a scam, don't buy from Bitmain etc etc, in this thread. It does NOT prohibit me from saying that in my own threads, if that is what I believe. It also has absolutely no impact on their rating in the Manufacturer trustworthiness thread [in which Bitmain just went down 10 points].

Continuation from previous thread: https://bitcointalk.org/index.php?topic=784897.0
When we compare the price of mining devices, we believe we should take all these factors into consideration.

1.   Cash cost
a)   Mining device sales price. This is the most obvious cost.
b)   Shipping cost. Shipping cost is trick, different shipping service will have different shipping time, and it will influence the time cost discussed in 2. Time cost.
c)   Incremental investment on PSU
d)   Tax: Some miners will have to pay VAT or other import tax.

2.   Time cost: We can estimate the time cost based on the projected gross mining revenue during the waiting time.
a)   Time on waiting period of pre-order. You know, shipping in two weeks.
b)   Time on shipping. Some shipping methods is much slower than our UPS shipping service, and the shipping time lost usually much larger the shipping cost we can save from choosing the slower carrier.

3.   Unstable cost: the unexpected downtime will cost the mining revenue. Usually a family miner will have full time job and family members to take care of. Hosting service will let the experts do the job.

S4+Umisoo Hosting has advantage on:
1) Shipping cost;
2) No PSU investment;
3) No VAT or import tax;
4) Pre-order waiting time cost is negligible
5) Shipping and deployment is seamless and fast.
6) S4 now has option for hosting.

According to our analysis frame, our S4 is still competitive against other options on the market if we take every factors into consideration for most of the miners around the world, assuming you have to buy PSU and electricity is not free.


So much parameters for you to compute and that may be correct and you may have a very little margin.
But customers have only two parameters to compute, the money goes out and the money earns, the ROI.
So your statement can't be justified even though if this is the lowest priced miner than others.
Hosting may be opted to save cost but that cannot offset buying miners.

The never ending progress picture is misleading because it shows S4 power efficiency coming in at under .5W/GH, but your official specs say the power efficiency is .69W/GH.

I don't think miners will buy this like crazy if they have brains. No offence to Bitmain.
Already discussed the about price a lot in the previous S4 thread and,
I think we should stop talking about the price of S4 now.
Let it passed, buy with your brain and not with your mind.

On a side note: I like the case and design, very tempting to buy on that side. Grin

I thought the S1 had the same efficiency as the S2?   Huh   I think that graph might be misleading?

Too expensive Bitmain, sorry.

Have you upgraded the firmware to the latest cgminer with these & other models, as you promised to do many weeks ago but still haven't - or are you still using the old, security vulnerable version?

Please post a link to the firmware.

I can't even buy spares for my S2 - what are the spares availability for this model - if any?

This is definitely not for the home miner.  Will just wait for the next batch of S3+ unless the price for that goes up as well.
