This tutorial is intended for the Antminer G2 Ethereum Miner of AMD RX570 GPU Miner. This Antminer G2 Ethereum GPU Miner is recently developed by Bitmain, it supports multi-currency mining including ETH, Zcash, XMR and so on. It hits a speed of 220MHash ±10% for ETH mining with EIGHT AMD Radeon RX570 video cards which makes it undoubtedly a pioneer machine in the field.

 

{Miner Specifics}

  • Brand: Antminer G2
  • Hash Rate: 220MHash ±10% (198MH/s ~ 240MH/s) for ETH mining
  • Operating System: CentOS 7.0 (Linux)
  • Pre-installed mining software: claymore9.7
  • Network Connection: Ethernet
  • PSU: with PSU

 

{Before Start}

The following background knowledge would be helpful to use the miner:

  • Knowledge regarding GPU and the GPU miners.
  • Knowledge regarding how to mine with a PC and how to mine with a video card.
  • Knowledge regarding CentOS 7.0 or Linux operating system.
  • Knowledge regarding ETH/ETC/ZEC or any others cryptocurrencies coins you are interested.
  • Knowledge regarding cryptocurrency such as wallet address, mining pools etc.

 

{Miner Connection}

  • This is the miner you will receive from EastShore.

  • A monitor is required (and a keyboard, a mouse) for configuration. (only needed when you configure the miner).
  • All the ports needed are on one side of the miner. Those ports are:
    • VGA port: for the monitor connection (HDMI is not supported)
    • USB port x 2: for the keyboard and mouse connection
    • Ethernet port

  • Connect the power cable of the PSU.
  • Tah-dah, connection done.

 

{Start Mining in ONE Minutes}

  • Power on the miner.

  • Wait for 3 ~ 5 minutes, then the operating system will start.
  • The mining system of the miner is the “CentOS 7.0” operating system. Generally, the operating system will start automatically, and the Desktop will show.

  • However, in some case, there may be an error occurred during the system starting. Don’t worry, just clicking the “Log Out” in the following picture.

  • If there is a pop-up window titled as “Computers & Contacts” appear after the operating system starts, just close it.

  • We will take ETH mining setting as an example in the following tutorial.
  • Setting up your own mining account:
    • Open folder “claymore9.7” on the Desktop
    • Right-click on the file “start.sh
    • Run “Open With gedit

  • The following command  is the ETH mining command

  • Set your own mining pool, wallet address and mining worker, then save the changes.

  • Close the file, and restart the miner (otherwise the mining settings will not be applied).

  • The pre-installed mining software “claymore9.7” will start automatically after 1 minute the operating system restarted.
  • However, the “claymore” works as a background program, so the GUI window will not appear. To get the mining details shown, we need to:
    • Open a terminal window on the Desktop
    • Input command: tail -f a.txt
    • Then the mining details will be shown

  • You can also use other mining software(should be Linux version) for the mining. 

 

{Troubleshoot}

Q: The hashing speed is lower than usual(eg. 100MH/s for ETH). / There are only 7 (or less) GPU works, not all the eight.

A:

  • First, please make sure if all the video cards are working. 
    • Right-click on the desktop, click “Open Terminal” on the pop-up menu.
    • In the pop-up windows, input command “lspci | grep -i vga
    • There should be EIGHT AMD video cards details shown in the windows (it will be showing as “RX 470/480 Series”)

  • If there are not EIGHT AMD video cards shown, then maybe some video cards in the case loosened up during shipping.
  • In that case, power off the miner first, open the case of the miner to insert those video cards properly and tightly. 
  • There is a screw on the case of the miner.

  • Take the screws out, and slide out the case.

  • There are eight video cards in the miner. Please make sure all the cards and cables are inserted tightly.
  • Power on the miner again to check if all the video cards appear. The problem would be solved.
