Solo mining with GUIMiner-Scrypt is possible but effectively pointless. Join a pool:
Windows Defender or other AV software may quarantine poclbm.exe because it detects “behavioral similarity to mining trojans.” To fix: GUIMiner-Scrypt Litecoin Mining Software For Windows Setup
Use a tool like MSI Afterburner to ensure your GPU stays below 75°C . 💡 Pro Tips for Success
Use GPU-Z or MSI Afterburner to monitor core clock, memory clock, and temperature while adjusting flags. Keep fans at 70-80% manually if needed. Keep fans at 70-80% manually if needed
Run for 1 hour, then check your pool’s dashboard for submitted shares. If you see “HW errors” (hardware errors) in the log, reduce intensity or thread concurrency. If it crashes, lower overclocks.
Download the latest version of from a trusted source (like the official GitHub or Bitcointalk thread). Extract the ZIP file directly into your excluded folder. Open the folder and run guiminer.exe . 3. Configure Your Mining Pool If it crashes, lower overclocks
You need a "pool" to combine your hashing power with others. Popular choices include or ViaBTC .
