How to use SimpleMining OS (SMOS)? (Setup Tutorial)

Understanding SMOS Architecture

1. SimpleMining OS is a Linux-based operating system specifically designed for GPU and ASIC mining operations. It boots directly from a USB drive and loads into RAM, leaving no footprint on internal storage.

2. The system relies on a web-based interface accessible via HTTP on port 80, eliminating the need for SSH or command-line interaction in most routine tasks.

3. Core components include the SMOS daemon, miner configuration manager, hardware monitoring engine, and auto-update scheduler—all running as lightweight background services.

4. Network initialization occurs through DHCP by default; static IP assignment requires editing the network configuration file located at /etc/network/interfaces via the web console.

5. GPU detection uses custom PCI-e enumeration routines that bypass standard kernel modules to ensure compatibility with legacy and overclocked video cards.

Initial Installation Process

1. Download the latest SMOS ISO image from the official SimpleMining website and verify its SHA256 checksum before proceeding.

2. Use BalenaEtcher or Rufus to write the ISO to a USB flash drive with minimum 8GB capacity and USB 3.0 support.

3. Insert the prepared USB into the target mining rig, power on the machine, and enter BIOS/UEFI to set USB as primary boot device.

4. Upon first boot, SMOS automatically detects connected GPUs and displays their model names, VRAM size, and PCIe lane configuration on the welcome screen.

5. The system assigns a local IP address and displays it alongside the default credentials: username admin, password admin.

Configuring Mining Pools and Wallets

1. Navigate to the “Miners” tab in the web interface and select the appropriate miner binary—Claymore, T-Rex, GMiner, or BFGMiner depending on algorithm and hardware.

2. Enter the pool URL using the format stratum+tcp://pool.example.com:3333, ensuring protocol and port match the pool’s requirements.

3. Input the wallet address in the designated field; SMOS validates address format against known cryptocurrency standards before saving.

4. Set worker name and password fields if required by the pool; some pools accept empty passwords while others mandate non-null values.

5. Adjust intensity, fan speed, and core/memory clock offsets under the “Tuning” section—values persist across reboots unless overwritten by auto-tune scripts.

Monitoring and Diagnostics

1. Real-time metrics appear on the dashboard: GPU temperature, fan RPM, hashrate per device, accepted/rejected shares, and uptime since last reboot.

2. Clicking any GPU row expands detailed logs showing miner startup output, driver version, and memory bandwidth utilization.

3. The “System Logs” page archives all daemon messages, including watchdog triggers, thermal throttling events, and pool connection retries.

4. Hardware alerts activate when GPU temperature exceeds 85°C or fan speed drops below 20% of maximum for more than 60 seconds.

5. Export raw sensor data as CSV via the “Export Metrics” button located in the upper-right corner of the monitoring view.

Frequently Asked Questions

Q: Can SMOS run on systems with AMD APUs integrated graphics?A: Yes, but only discrete GPUs are utilized for mining; integrated graphics remain inactive during operation unless explicitly enabled for display output.

Q: Is it possible to run multiple mining algorithms simultaneously on different GPUs within one SMOS instance?A: No, SMOS enforces a single global miner configuration; each rig must run identical algorithms across all active devices.

Q: What happens during an automatic OS update?A: Updates download in the background, then apply during the next scheduled reboot; miner processes stop gracefully, and configuration files remain untouched.

Q: Does SMOS support NVMe-based swap partitions for memory-constrained rigs?A: Not natively; the system avoids disk-based swap entirely and relies on RAM-only execution to prevent wear on USB drives and maintain stability.
