Overview

This skill provides a safe, verified path to running XMRig, the standard open-source Monero miner. It focuses on:

• Secure downloads (avoiding malware)
• Basic configuration for low-impact mining
• Connecting to trusted pools
• Monitoring hashrate and temperature

⚠️ Important Disclaimer

• Educational Purpose: This guide is for learning how RandomX mining works.
• Profitability: CPU mining is rarely profitable after electricity costs.
• Hardware Safety: Monitor temperatures. Do not mine on laptops without adequate cooling.
• Ownership: Only mine on hardware you own and control.

Step 1: Download XMRig Safely

NEVER use curl | bash or download from unofficial sites.

1. Go to the official GitHub releases: https://github.com/xmrig/xmrig/releases
2. Download the latest stable version for your OS.
3. Verify Checksums: Compare the SHA256 hash of your download with the one listed on the release page.

Step 2: Create a Configuration File

Create a file named config.json in the same folder as XMRig.

Basic Low-Impact Config (20% CPU Usage)

{
    "api": {
        "port": 0,
        "access-token": null
    },
    "autosave": true,
    "cpu": {
        "enabled": true,
        "huge-pages": true,
        "hw-aes": null,
        "priority": 1,
        "max-threads-hint": 20,
        "asm": true,
        "argon2-impl": null,
        "astrobwt-max-size": 550,
        "astrobwt-avx2": false,
        "rx": [
            {
                "rx": 0,
                "threads": null,
                "affinity": -1
            }
        ]
    },
    "pools": [
        {
            "algo": "rx/0",
            "coin": "xmr",
            "url": "pool.supportxmr.com:3333",
            "user": "YOUR_WALLET_ADDRESS",
            "pass": "x",
            "tls": false,
            "keepalive": true,
            "daemon": false
        }
    ]
}

Replace YOUR_WALLET_ADDRESS with your actual Monero address.

Step 3: Run XMRig

Windows

1. Open PowerShell in the XMRig folder.
2. Run: .\xmrig.exe

Linux/macOS

1. Open Terminal in the XMRig folder.
2. Make executable: chmod +x xmrig
3. Run: ./xmrig

Step 4: Monitor Performance

• Hashrate: Look for speed 10s/60s/15m in the output.
• Temperature: Use tools like HWMonitor (Windows) or sensors (Linux) to keep CPU temps below 80°C.
• Pool Stats: Check your pool’s website (e.g., supportxmr.com) with your wallet address to see accepted shares.

Troubleshooting

Security Best Practices

1. Firewall: Allow XMRig only outbound connections to pool ports.
2. Updates: Check GitHub regularly for security patches.
3. Anti-Virus: XMRig is often flagged as "HackTool" or "CoinMiner." This is a false positive for legitimate use, but be aware. Add an exception if you trust the source.
