XMRig setup and tuning

Get XMRig only from xmrig.com or github.com/xmrig/xmrig/releases and compare the SHA-256 with the published one. Antivirus tools often flag miners; never download "unlocked" or repackaged builds.

{
  "autosave": true,
  "cpu": { "enabled": true, "huge-pages": true },
  "randomx": { "1gb-pages": false },
  "donate-level": 1,
  "pools": [
    { "url": "pool.example.com:3333", "user": "YOUR_XMR_ADDRESS", "pass": "rig1", "tls": false }
  ]
}

For P2Pool, the pool url is 127.0.0.1:3333 (your own P2Pool). The default donate-level of 1% goes to XMRig's developers.

sudo sysctl -w vm.nr_hugepages=1280      # ~2.5 GB of 2 MB pages; adjust to threads
echo 'vm.nr_hugepages=1280' | sudo tee /etc/sysctl.d/60-hugepages.conf
# XMRig prints "huge pages 100%" when it worked. Running XMRig as root also enables the MSR mod (extra speed on many CPUs).

• Low hashrate: check huge pages %, thermal throttling, and threads (≈ L3 MB / 2)
• Rejected shares: unstable overclock or wrong algorithm/port
• Connection errors: firewall, wrong port, or TLS mismatch
• Laptop: expect throttling; mining on battery is a bad idea
