Among all the mining programs that have come and gone, CGMiner still holds a kind of legendary status.
Version 4.11.1 was one of its last major releases — a stable, reliable build that miners stuck with long after newer forks appeared.
It’s lean, command-line based, and brutally efficient — no pretty interface, just raw control and performance.
CGMiner was originally written by Con Kolivas, a Linux kernel developer, and it shows — the tool behaves more like a professional system utility than a hobby project.
If you can live without a GUI and don’t mind typing commands, you’ll find it’s still one of the most precise and configurable mining programs ever built.
Technical Overview
| Attribute | Detail |

| Version | 4.11.1 (final major release supporting ASICs) |
| Purpose | Bitcoin and SHA-256 ASIC mining |
| Interface | Command-line (text-based) |
| Supported Devices | ASIC miners (Bitmain, Avalon, Antminer series, etc.) |
| Key Features | Stratum support, fan control, monitoring, overclock, failover pools |
| License | Open-source (GPLv3) |
| Risk Level | Low — stable and proven |
| Best Use Case | Dedicated Bitcoin mining with ASIC hardware |
What It’s Like to Use
Running CGMiner feels like stepping into the early days of crypto — when mining was still personal and raw.
You launch it from the terminal, see those green lines scroll by, and suddenly your hardware starts humming with purpose.
It gives real-time stats — hash rate, temperature, fan speed, and accepted shares — updating faster than most GUI miners ever could.
Everything is done through simple flags or configuration files: set your pool, your worker, maybe a fan speed or voltage tweak, and you’re mining.
No installers, no ads, no background junk.
Just one executable that does exactly what it’s supposed to.
The best part? It’s rock-solid. CGMiner 4.11.1 can run for weeks on end without crashing or losing connection, something even many newer miners can’t claim.
Typical Workflow
1. Download CGMiner 4.11.1 from the official GitHub or archived sources.
2. Extract it to a dedicated folder.
3. Create a .bat file (on Windows) or shell script (on Linux) with your configuration:
cgminer.exe -o stratum+tcp://pool.address:3333 -u worker -p password –api-listen
4. Save and run the script.
5. Watch real-time stats — accepted shares, hash rate, and temperature updates.
6. To stop mining, press Q in the console.
Where It’s Still Useful
– Running older Antminer or Avalon ASICs that rely on CGMiner’s protocols.
– Testing hardware performance or fan control on legacy rigs.
– Building minimal Linux-based mining systems.
– Educational setups for learning low-level mining configuration.
– Situations where lightweight, scriptable tools are preferred over GUIs.
Important Warnings
– GPU mining support was removed after version 3.7.2 — this build is ASIC-only.
– Always download from verified repositories — fake “CGMiner” packages often carry malware.
– Avoid editing low-level voltage settings unless you know your hardware.
– Keep pool credentials secure — CGMiner saves configs in plain text.
– Some USB-based ASICs require specific drivers (WinUSB or Zadig) before detection.
Even though it’s nearly a decade old, CGMiner 4.11.1 still represents what mining software should be — lightweight, transparent, and under your full control.
It’s not flashy, but it’s the benchmark by which many others were measured.
