Official Manual

  • You can also get the official manual here

Before Start

  • Please prepare a ATX PSU ( >=550w and with 6pin x 2)
  • Connect the miner to the router by internet cord.
  • The default configuration IP of the miner is “192.168.1.xxx”, so, plz make sure the IP your router is “192.168.1.1”. (for how to find the configuration IP, see section {Configuration IP} below)
  • For miner configuration, plz use the ethernet cord to connect the miner to the same router which your PC also connected. (Your PC is just needed for miner configuration)
  • If you have many miners, you need to change the IP address of those miners to avoid the IP address conflict. (For how to change the IP of the miner, see the section {WAN setting} in the official manual above)

Check Your Network

  • Pressing the windows key + the R key. So ‘Windows + R’. This should give you a small window called ‘run’.
  • Enter ‘cmd’ in the window, and hit the enter key. This should open a new window.

  • Input command “ipconfig”, it will show the details of your network.
  • Make sure the “Default Gateway” is “192.168.1.xx”.
  • If the default gateway is not “192.168.1.xx”, please change to another router (which give a default gateway as “192.168.1.xx”), or, change the IP of your router to “192.168.1.xx”

PSU NEEDED


  • Plz prepare a ATX PSU ( >=550w; with 6pin x 2)
  • Plz make sure your PSU is powerful enough; 12V DC is above 45.5A is very great!
  • check out this PSU

Setting Up the PSU

  • Suppose you use an ATX Computer Power Supply as your mining PSU.
  • You will need 1 jumper wire. On the PSU’s 24pin motherboard power cable, you have to cross the “Green” line and the “Black” line. (The PSU has a computer inside and it communicates with the motherboard. For this setup, there is no computer motherboard to connect to, so, we have to make the PSU think it’s connected to the motherboard and the PCI and PCI-Express ports are needing the +12 V power.


Miner Connection

  • There are 4 x 6pin connectors in 2 rows. But actually, you need only 2 of them.


  • Then the most important thing is:
    • Please plug each of the 6pin cords of your PSU into a 6pin port in each row (Don’t plug into ports in the same row or the mining will never start…).
    • Don’t plug cords into all the four port.


  • Why? Because there are 2 blades inside the miner, each blade needs a 6pin as power input.


4Configuration IP

  • The default IP is “192.168.1.99”.
  • However, the IP might have changed when testing, so please use IP scanner to scan the configuration IP if you can’t log in the configuration page via default IP, check here for how to scan out the IP address of the miner.

MINING GUILD

(This section is published on 22th July 2014. The miner may not act exactly as we described below with the passage of time or the improvement of the miner. In that case, please don’t worry.)


  • Connect all the cords and ethernet cord.
  • Power on the PSU.
  • The fan will run, but, just a few seconds, and then the fan will stop running. YES, it’s normal. Don’t worry.
  • Just wait for about 1~3 minutes, the fan will run again (and the miner maybe beep twice or once)…
  • (After you configured the miner when you first time use it, the mining will start automatically. Every time, you power on the miner, the miner will act as above description, and then mining will start)
  • Now, we can configure the miner now.
  • Login the configuration page via the configuration IP(eg. 192.168.1.99). The default username is “root” and password is “root” too, and then click “Login”. (ps: sometimes, maybe you will get a page full of error message when you open the login page, plz don’t worry, just power off your miner, wait for some seconds, then power on again…)

  • In the “Miner Configuration”, configure your mining pool address, mining account, miner password etc. And click “Save & Apply”.


  • Wait for about 1~2 minutes.(ps: while you are waiting, you’d better not to click anything, in our test, sometimes(just sometimes), I click something while I am waiting, the mining will not start, the miner status page has no any data, I don’t know why…)
  • While waiting, the miner may be beep for a while(or maybe not beep, in any case , plz don’t click anything and wait for about 1~2 minutes). Just let it beep…
  • When the miner stops beep, the mining is starting… You can check the mining status in the “Miner Status” page. (ps: sometimes, the page may show no any data, it just occur sometimes, however, in that situation, plz just power off your miner, and then power on it again.)


  • The miner will get a speed about 441GH/s at the frequency “218.75”, and will get a speed about 478GH/s when to overclock.
  • The mining will start automatically when power on after you configure it.
  • Sometimes, the ASIC status on the miner configuration page may show as “xxx” or “—“, please don’t worry, just try to wait for a longer time or restart the miner and the miner will be ok. And please make sure you put the miner in some places cooling.
  • Sometimes, the speed of the miner may get shown as a very low speed(eg. 27g or something like this), this is a known display bug of the Antminer S3, don’t worry, the speed in your pool will be normal. (Also, you can try to restart the miner)

Upgrade Firmware

If your miner works very well, please skip this section.


  • Then click “Proceed” in the next page.


  • Waiting for 1~3 minutes for changes to be applied.


  • Then the page will go to the login page. Firmware upgrade success.


  • Use the default password “root” to log in and configure your miner.
  • Important: After you upgrade the firmware, you need to go to the “Advanced Settings” and set the Frequency, or the mining will not start…

  • The default frequency is “218.75”.
  • We suggest setting the frequency as “218.75”. And also, you can also try other frequencies.

  • The default frequency is “218.75”.
  • We suggest setting the frequency as “218.75”. And also, you can also try other frequencies.

OVERCLOCK

  • Anyway, overclock is very easy now… The only thing you need to do is: go to “Miner Configuration” –> “Advanced Settings” page and select a frequency for your miner.

  • The default frequency is “218.75”. Any frequency > 218.75 is overclocked…
  • If your miner has no the page (“Miner Configuration” –> “Advanced Settings”), please upgrade your firmware first. For how to upgrade the firmware, please see the section {Upgrade Firmware} above.

Other Reference

  • How to make the miner cooler ? You can open the case and lose the case.

  • Sometimes, I got an unbelievable speed at the “Miner Status” page, but at the same time, I get a normal speed at the pool(like below pictures showing). I just restarted the miner (actually, I reboot the miner via WinSCP), and then everything is ok… I don’t know why, but it just happened. So, I think maybe there is still some problem with the AntMiner mining system at the speed display function. Don’t worry, when it happened, just restart the miner…

Sometimes, the display of the fan speed is inaccurate, while the temperature of the miner is not so high. However, the inaccurate display of the speed of the fan happened sometimes; So, if you get this, plz don’t worry…

  • Unbelievable Speed at Miner Status Page

  • Normal Speed at Pool

speed02
speed03
  • Sometimes, there is no any data showing on the “Miner Status” page, in that case, plz:
    • Check your home network setting, is it normal?
    • Power off the miner, then wait for some seconds, and power on the miner again.
    • Upgrade the firmware. (some old version of the mining system maybe get this “no data” problem, plz upgrade the firmware to the newest ones)
    • Check if all the cables inside the miner are connected tightly.
    • Check the mining pool address you set in the “Miner Configuration”, can your home network connect to the pool?
    • After you set the pool address etc, and click “Save&Apply”, while you wait the setting applied, plz don’t click anything.
    • Try to reset the miner.

Reset Antminer


If your miner works very well, please skip this section. You don’t need to reset the miner if it works well.
Anyway, if your miner got any troubles, you can try to reset it first. Here are the steps to reset the miner:
  • Power on the miner.
  • Wait for 1 minutes, until the miner start mining.
  • Take a paper clip and press the reset button (as shown in the following picture) for 10 seconds.
  • Then the red light will keep flashing and then miner reset successfully.
  • Wait for minutes and then you can log in the configuration page via the default IP 192.168.1.99.



Trouble Shoot

We are very sorry for the trouble you got, the miner industry is a new industry, so the products are not so perfect sometimes. Anyway, if you got any troubles, please try to check:

  • Sometimes, there is no any data showing on the “Miner Status” page, in that case, plz:
    • Check your home network setting, is it normal?
    • Check the mining pool address you set in the “Miner Configuration”, can your home network connect to the pool?
    • 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.
    • Upgrade the firmware. (some old version of the mining system maybe get this “no data” problem, plz upgrade the firmware to the newest ones)
    • Check if all the cables inside the miner are connected tightly.
    • After you set the pool address etc, and click “Save&Apply”, while you wait the setting applied, plz don’t click anything.
    • Try to reset the miner.
  • Sometimes, maybe you will get a page full of error message when you open the login page, plz don’t worry, just power off your miner, wait for some seconds, then power on again
  • Change to another two 6pin ports on the box of the miner. (eg. In the following picture, you used the port “A”, “B” as power input port, so, plz try to change to port “C”, “D”. Because the port may be poor contact)


  • Make sure all the cords inside the miner are connected tightly. (those cords are data transfer cord and fan cords)


  • Is the heat dissipation of the miner normal? Because the miner maybe stop mining if the temperature is too high. So, please:
    • Reset the miner. See section {Reset Antminer} above.
    • Upgrade the firmware. See section {Upgrade Firmware} above.
    • Check the PSU: Is the 12V DC of your PSU enough to run the miner?
      • If the PSU you using run several miners, plz try to use the PSU only for 1 miner, see if the miner works well. If the miner do works well when the PSU only run 1 miner, then the PSU you are using may have no a strong 12DC for several miners.
      • Try to get another PSU for the miner.
    • Try to run the miner at a lower “frequency”. If you overclock it, please try to run it in a normal frequency.
    • Configuration all correct? Please try to reconfigure the miner.
    • Is your network environment normal? (If the miner can’t connect to the pool, it will stop mining and trying to reconnect to the pool). Please check the network settings, especially the setting of the router and DNS. If the DNS setting is not correct, then the Pi in the miner maybe cannot recognize it, which leads to a failure of connection to the pool. Is the miner directly connected to the router? Have any other devices occupied the IP of the miner? To check the networking environment or change to a new networking environment is suggested.
    • Does the pool you use is normal? try to change to another pool.
    • Check the cords inside the box. Open the box, there are some cord inside. Plug tightly every cord.
    • Check section {Q & A} below for more information about problems may get when mining.

Q & A

1. How do I reset my Antminer?

  • Please see the section {Reset Antminer} for how to reset it.

2. How do I upgrade my firmware?

  • Please see the section {Frimware Upgrade} for how to upgrade the miner.

3. My Mining Pool Speed is slower than 441GH

  • Please check your AntMiner’s Mining Status Page. If the status showed 418.95GH/s – 441GH/s, your miner is working as it should. The rated speed of Antminer S3 is 441GH/s and a speed around 441GH ± %5 is normal.
  • The mining pool speed calculation is based on what you transmit to the pool after the hashing. It is normal to see the mining pool GH/s speed fracture and sometimes it may show significant lower hashing speed. Please check your network condition and maintain a stable internet connection. In our test, I have seen 420GH/s speed at BTCGUILD when my Internet connection was cutting in-out for a short period of time due to the ISP problems.

4. AntMiner Keeps Shutting Down…

  • AntMiner could be powered on for 50 minutes before it shuts itself down. OR It could be powered on for about 30 seconds then it shuts down: Your problem is more than likely in the PSU. Please check the jumper cable to make sure the PIN16 (Green) and PIN17(Black) are crossed. (Make sure you are not using the thin loose wire or paperclip for this) If the Jumper Cable is jammed in and set correctly, it could be your power supply unit.
  • Please make sure the 12V DC of your PSU is strong enough. To check the PSU, run your AntMiner in 1 Blade Mode. Disconnect all the power cables from the 2nd Blade. Disconnect the white plug on the top from the 2nd Blade. Then Power On the AntMiner. If the problem was in your PSU, AntMiner will power on and it will start mining at about 220GH/S.

5. I see “x” in the ASIC Status For the ASIC status wise, “x” doesn’t necessary means the chip is faulty or failing.

  • If the hashing power seems to be affected, please check your PSU and wiring and reboot and check the status a few times. It should go back to an average 441 ± 5% GH/s per AntMiner. when you are getting “x” on the ASIC chip status, please turn off the Antminer and double check your PSU cables are connected well and restart.
  • Check the status in about 5 minutes and every 30 minutes for a few hours and see if the “x” are showing up constantly at the same chip or randomly changes or completely disappear.
