Altcoin GPU Mining

GPU Mining — Tutorial

GPU mining uses your graphics card to mine. For Scrypt-based coins, the classic GPU miner is SGMiner. SGMiner is explicitly a “Scrypt GPU miner” and is based on cgminer/cpuminer lineage. Important: Only download miners from official sources of SGMiner. Avoid random “miner packs” and unknown mirrors.

What you need:

Steps

Step 1 — Get an Altcoin wallet address

Download and Install the official Altcoin wallet (desktop / linux) and create a receiving address: open the wallet → Receive → generate/copy a new address. Save that wallet address.

Step 2 — Download GPUminer - SGMiner

  • SGMiner is a multi-threaded multi-pool GPU miner designed for Scrypt-based cryptocurrency.
    Download from Official repo: sgminer-dev/sgminer.
  • Step 3 — Install GPU drivers

    Make sure your GPU drivers are installed and up to date. SGMiner is historically strongest with AMD/OpenCL-style setups, but the key concept is: your system must have working GPU compute drivers installed before mining will work.

    Step 4 — Create a simple config file

  • Download from the official Releases page (above), extract into a folder like: C:\Altcoin\miners\sgminer\ or ~/altcoin/miners/sgminer/
  • In the SGMiner folder, create a file named sgminer.conf and paste this template
    (edit POOL + USER):
  • {
      "pools": [
        {
          "url": "stratum+tcp://POOL_HOST:POOL_PORT",
          "user": "YOUR_ALTCOIN_WALLET_ADDRESS",
          "pass": "x"
        }
      ],
      "kernel": "scrypt",
      "intensity": "13",
      "worksize": "256",
      "thread-concurrency": "0"
    }
    Warning: Beginner tip: If you’re not sure what intensity/worksize means, keep the defaults above. You can tune later once you confirm it runs.

    Step 5 — Start SGMiner

  • Windows:
    sgminer.exe --config sgminer.conf
  • Linux:
    ./sgminer --config sgminer.conf
  • ---

    GPU Pool Mining - CGMiner command template

    • Example:
      cgminer -o stratum+tcp://POOL_HOST:POOL_PORT -u YOUR_ALTCOIN_WALLET_ADDRESS -p x --scrypt
    • Expected behavior: the miner opens, connects to the pool, and shows GPU hashrate. If it fails to detect GPU or crashes, that’s usually a driver / OpenCL compatibility issue (common on modern systems).

    GPU Safety & Troubleshooting

    • Heat & power: GPU mining can pull significant power and generate heat; monitor temps.
    • Driver issues: Most GPU mining failures are driver/OpenCL problems.
    • Start conservative: If it’s unstable, lower intensity or stop and fix cooling/driver first.
