eastshore tutorial for antminer S9

Antminer S9 is the newest and first 16nm bitcoin miners in the bitcoin mining market.

The AntMiner S9 is Bitmain’s newest version in the AntMiner series. It boasts a state-of-the-art BM1387 custom-made chip using 16nm technology. There are several submodels of Antminer S9. The submodel we got currently(07/26/2016) is: 11.85TH/s @ 1172w.

In this tutorial, we will introduce the setting-up for Antminer S9 16nm bitcoin miner.


{Before Start}

  • Please prepare PSUs (can afford the power >= 1500w and with 6pin x 10); You can use several PSUs to connect to one miner. But please DON’T connect 1 PSU to more than 1 miner or more than one hashing board.
  • Connect the miner to the router by internet cord.
  • For miner configuration, please 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)


{Update 2017-05-09}

  • The newest batch of the Antminer S9 is pre-installed with the latest firmware.
  • Miner needs about 10~20 minutes to initialize itself before start mining. While waiting, you may notice that the kernel log shown as “CRC error counter=0“, that means, there is no error with the CRC(Cyclic redundancy check), this is NOT an issues. Please waiting patience.
  • The fan of the miner won’t spin at high speed all the time. Generally, the fan will work at a speed around 2000~3500(NOT 5000+). The fan will NOT work at its FULL SPEED if not needed.
  • Generally, the temperature of the PCB will be around 65℃~90℃, the temperature of the chip will be around 80℃ ~115℃ which is normal.


{Miner Connection}

  • Please check if all the cables on the miner to make sure they are inserted tightly.

  • There are 10 x 6pin ports on the miner. All the 6pin ports are needed. You need to connect all the 6pin ports to your PSU. (Don’t forget to connect the 6pin port on the little green controller board)

three hashing boards of antminer s9

  • Important: there are 3 hashing boards in the miner, and 3 x 6pin ports on each hashing board. DON’T connect more than one PSU to one hashing board. (That’s means, the 6pin cords you connected to one hashing board should come from only one PSU.). See below pictures for the correct connection and the incorrect connection.
  • Correct Connection:


  • Incorrect Connection:


  • Insert the ethernet cord.
  • Miner connection DONE.

{Mining Guide}

  • Power on the miner. (Important: If you used several PSUs for the miner, you should power on the PSU which connected to the 6pin port on the little green controller FINALLY).
  • Wait for about 1~2 minutes.
  • Then, please use software to scan out the IP of the miner on your PC. For how to scan out the IP of the miner, check here: https://www.eastshore.xyz/how-to-scan-out-the-configuration-ip-address-of-the-miner/
  • Then, you can log into the miner configuration page for miner configuration. Please open your internet browser, such as Google Chrome, IE etc. and open the IP address you just scanned out (For example,  The username and the password are all “root
  • Navigating to the “Miner Status” page and keep refreshing the page until some data (Speed, miner account, pool etc.) is shown on the page (This means, the mining is starting. Generally, the miner need about 3~7 minutes to start mining). The fan of the miner maybe gets loudly and slowly for several times while you are waiting. And sometimes, the data on the page maybe disappear again just a few seconds or one minute after the mining starts, don’t worry, please waiting for the miner working constantly.
  • Navigating to the “Miner Configuration“ page, configuring your mining pool address, mining account, miner password etc. Then click “Save & Apply”.
  • Save the changes, then wait for about 1 minutes for the setting applying.
  • Change to the page “Miner Status” again, and please refreshing the page until there are some data shown on the page. Then the mining is starting.

  • The “Miner Status” page of Antminer S9 is quite different from the “Miner Status” page Antminer S7. You will find out that there are two temperatures here, one is “Temp(PCB)” and another is “Temp(Chip)“.

two temperatures of antminer s9

  • The “Temp(Chip)” may get as high as 100 degrees(or much higher than 100 degrees), that’s normal, please don’t worry.
  • The “Temp(PCB)” is the temperature of the miner.
  • If there is no any data shown for a very long time (for example 30 minutes) or there are a “BiBi” noise comes from the miner, please try to restart the miner (power off it, wait a minute, then power on it again). After restarted, please change to the page “Miner Status” page and waiting for data showing.
  • If you have any problem, please level us a comment, we will reply your comment to help you figure out the problem.


{Fix Socket Error}

Sometimes, when you use Antminer S9, you may get the socket error. For example, there may be something like “Socket connect failed: Connection refused” showing on the “Overview” page of the Antminer S9.

In fact, the socket error is quite normal, it means the miner is trying to set its own frequency automatically. (All the Antminer S9 produced after 2016-11-02 will set its own frequency automatically after powered on). In the most occasion, you can safely ignore this error. The miner will start mining automatically after 10~20 minutes and the socket error will be gone.

However, here are also some suggestions to fix those socket errors if the errors keep showing:

  • Wait longer. Please try to wait longer until the miner running. The miner needs about 10~20 minutes to initialize itself(In some occasion, it may need up to 30~40 minutes for initializing itself). During this period, the miner may show some message like “Socket error”. Don’t worry, please try to wait a longer time to see if the miner starting mining.
  • Try to restart the miner. When you first use the miner, if the miner doesn’t start to work for a really long time (for example, 30 minutes), please try to restart the miner. Sometimes, we do get this situation when we test the miner. Usually, after restarting, the miner will work perfectly.
  • Update firmware: If the socket errors keep showing, please try to upgrade the firmware to fix the error:
    • Down this edition of firmware: Antminer-S9-all-201610270319-autofreq-user.tar.gz
    • Navigating to “System –> Upgrade” to upgrade the firmware. Then modify the name of the worker, click Save&Apply (DON’T change frequency). After updating the firmware, the miner will need longer time (20 -30 minutes) to start working, wait patiently, don’t restart it or power off or change something else. Wait until you see some speed data on the miner status page. At the meantime, make sure the network is stable.
    • Then the miner will start mining automatically, and the socket errors will be gone.

{Mining Tip}

Please pay more attention to the following tips if you are running several miners(<= 10 miners) together:

  1. The heat dissipation
    • Please make sure all the hot wind which comes out of the fan(of the miner) will be exhausted timely.
    • And what’s more, all the hot wind would be exhausted in the same direction, and there is no hot wind will be blown into other miners’ air inlet end.
  2. If you connected several miners into one power strip which is connected to the socket on the wall, you need to:
    • Please check the maximum current rating of your power strip.
    • For example, in China, for some of the power strips, the maximum current rating is about 2000w. As the power consumption of the miner is nearly 1400w, so it is better to connect ONLY ONE miner into one power strip. Or the miner might stop working.


{Mining Speed Note}

(Update: this section is for the submodel 11.85 TH/s @ 1172w)

  • The submodel of Antminer S9 we got currently is “11.85 TH/s @ 1172w” with the “Default Frequency” set as “550M”.

specifics label of antminer s9

  • The rated speed of Antminer S7 is “11.85 TH/s ± 5%”, so the speed may fluctuate between “11.25 TH/s ~ 12.44 TH/s”.
  • In our test, the “GH/S(5s)” on the “Miner Status” page may change frequently, but the “GH/S(avg)” will keep stable. So please don’t worry about the frequently-changed speed of “GH/S(5s)”.
  • However, if both the “GH/S(5s)” and  “GH/S(5s)” are very low (eg. 10TH/s), please just restart the miner, and the speed will be normal.

{Trouble Shoot}

For all the troubles you get in the mining, please try the following suggestions:

  • Check your home network, the mining pool to make sure all the network are working well.
  • Check if all the cables on the miner inserted tightly. Especially the three cables connected to the hash board. They may get loose in the shipping.
  • Did you connect all the ten 6pin ports on the miner to your PSU? All the ten 6pin ports are needed for mining.
  • Have any heat sinks fallen off? Give the machine a gentle shake and double-check that no heat sinks have become loose or fallen off in transit.
  • Try to reset the miner. There is a reset hole beside the internet port. After the miner powered on and running, waiting for 5 minutes(until the miner start mining), please get a sharp pin and press the hole for about 10 seconds. Then please wait for about 5 minutes for the resetting. You may need to rescan the IP address of the miner after reset.

  • Try to upgrade the firmware: check tutorial here: https://www.eastshore.xyz/how-to-upgrade-the-firmware-for-a-bitcoin-miner/
  • Miner keeps restarting: If you also bought the Antminer 1600w PSU(APW3-12-1600-B2) for the miner, please make sure your home voltage is stable. The working voltage of this PSU should be >= 205V. If your home voltage is not stable, the PSU may stop working(or with the fun working but no power output). In this occasion, you may need to get a voltage stabilizer for the PSU.
