Bitmain Antminer L3, L3+, L3++ ASIC Miner

5.03.2026

Bitmain Antminer L3, L3+, and L3++ are ASIC miners for mining cryptocurrencies using the Scrypt algorithm, including Litecoin, Dogecoin, Pepecoin, Bellscoin and QUAI. Released by Bitmain in 2017–2018, these miners remain among the most popular Scrypt devices.

🔊 Noise Level:

The operating noise level is 62–76 dB: Antminer L3 — 62 dB, L3+ and L3++ — 76 dB. Due to the high noise level, the ASIC is not suitable for home use without a soundproof enclosure.

✅ Kryptex PPS+ Pool has tested and supports all Bitmain Antminer ASIC miners.

💎 On the Kryptex Pool, Scrypt ASIC miners can operate in merged mining mode (LTC+DOGE+PEP+BEL), allowing you to mine Litecoin, Dogecoin, Pepecoin, and Bellscoin simultaneously.

Setup Bitmain Antminer L3, L3+, L3++

  1. Prepare the equipment:

    • Connect the Antminer L3 to a power outlet.
    • Connect an Ethernet cable (network cable) from your router to the ASIC.

  2. Power on the device:

    • Turn on the miner. You will hear the fans spinning, indicating that it has started.

  3. Find the device's IP address:

    • On a computer connected to the same network as the ASIC, download the Bitmain Antminer IP Reporter Tool.

    • Launch the program and click "Start".

    • On the ASIC itself, press and hold the "IP Report" button for a few seconds.

    • The utility will display your device's IP address.

  4. Access the management interface:

    • Open a browser and enter the IP address you found. This will direct you to the Antminer management interface.

    • Log in using the default credentials: username: root, password: root.

  5. Configure pool settings:

    • In the interface, navigate to the "Miner Configuration" section.

    • Enter the pool data (pool address, wallet address, and worker name). Use the data from the table below.

    • Worker — specify wallet and worker name in the format: LgETtY86dfiWsgD3Mmcx1PtzhCdeYUVBaL.AntminerL3, where LgETtY86dfiWsgD3Mmcx1PtzhCdeYUVBaL is your LTC wallet address, AntminerL3 is the name of your ASIC.

      Coin Mining Address — Pool Address Miner Name — Wallet Address and Worker Password
      LTC+DOGE+BEL+PEP ltc.kryptex.network:7016 or ltc-eu.kryptex.network:7016 or ltc-ru.kryptex.network:7016 or ltc-us.kryptex.network:7016 or ltc-sg.kryptex.network:7016 LTC_WALLET_ADDRESS.WORKER_NAME x or leave blank
      QUAI quai-scrypt.kryptex.network:7042 or quai-scrypt-eu.kryptex.network:7042 or quai-scrypt-ru.kryptex.network:7042 or quai-scrypt-us.kryptex.network:7042 or quai-scrypt-sh.kryptex.network:7042 or quai-scrypt-hk.kryptex.network:7042 QUAI_WALLET_ADDRESS.WORKER_NAME x or leave blank

  6. Make sure to complete all three lines with the settings of the same pool. Click "Save & Apply" to save the settings and restart the ASIC.

  7. Verify ASIC operation.

    • Once the restart is complete, wait a few minutes, then open the ASIC interface in your browser again.

    • On the "Miner Status" page, you'll see the current status: hash rate, uptime, temperature, and other metrics.
