How to Dual-Mine a GPU Coin + Monero at the Same Time (2026)

Guide · ~8 min read · by the Hydrax.GG team

Your mining rig has two engines, and most people only run one. While your GPU mines a coin, your CPU sits nearly idle — and it could be mining Monero. Dual mining puts both to work at once, for almost no extra effort.

This is the modern, sensible form of dual mining: not two coins fighting over one GPU, but a GPU coin and a CPU coin running on separate hardware so they don't step on each other. Here's why it works, how much it actually adds, and how to set it up.

What dual mining means (the version that actually makes sense)

"Dual mining" has meant different things over the years. The form worth doing in 2026 is cross-hardware: your GPU mines a GPU algorithm — KawPow coins like Ravencoin and Neoxa or Etchash for Ethereum Classic — while your CPU mines Monero with RandomX. Two different chips, two different coins, one rig.

The reason this is smart is simple: the GPU and CPU are separate pieces of hardware. Mining Monero on the CPU doesn't take cycles away from the GPU, so the GPU coin keeps earning almost exactly what it would alone — and the Monero is bonus income on top.

Why it works (and why it's nearly free money)

The only real cost is the extra electricity the CPU draws while it works. That means dual mining pays off most when your CPU is reasonably capable and your power rate is moderate — so, as always, check the numbers for your exact setup rather than assuming.

What you need

  1. An NVIDIA GPU for the GPU coin, and a CPU for Monero (any modern multi-core processor contributes).
  2. A wallet address for each coin — one for the GPU coin, one for Monero.
  3. A pool for each coin (a GPU-coin pool and a Monero pool).
  4. A dual-mining miner. We'll use the free HydraX miner, which runs a GPU coin and Monero together from one program.

How to set it up, step by step

  1. Download and unzip the miner to a folder you can find.
  2. Pick your GPU coin — Ravencoin, Neoxa, Neurai, Frencoin or Ethereum Classic — and set its pool and your wallet for it.
  3. Add Monero — set your Monero pool and your XMR wallet alongside the GPU coin.
  4. Choose the dual mode (for example, a GPU coin + XMR) so both engines start together.
  5. Run it and watch the console. You should see the GPU build its DAG and report a hashrate, and Monero start reporting its own hashrate on the CPU. Confirm accepted shares for both — that's proof each side is earning.

The one setting that matters: leave the GPU some CPU

This is the mistake that turns dual mining into a loss. If you let Monero mine on every CPU core, there's nothing left for the CPU to feed the GPU its work — and a starved GPU's hashrate can crater, costing you far more than the Monero you gained. A well-built dual miner automatically reserves a couple of CPU cores to keep the GPU fully fed, so the GPU coin holds its full hashrate while Monero uses the rest. HydraX does this reservation for you when a GPU coin is active, which is the whole point of running it as one integrated program rather than two miners fighting over your CPU.

Heat and power: the honest caveats

Running both engines means the whole machine works harder, so it draws more power and runs warmer than GPU-only mining. Keep airflow strong, watch both GPU and CPU temperatures, and remember the CPU's extra wattage is a real line on your power bill. None of this is a dealbreaker — it just means you should confirm the Monero income clears the added electricity, especially if your power is expensive. Run your numbers through the free mining calculators to track your profit and you'll know for sure.

Frequently asked

Which GPU coin should I pair with Monero? Whichever pays most for your card today — KawPow coins or Ethereum Classic. The Monero side is the same regardless. Compare GPU coins in the calculator and read the most-profitable-coin guide.

Can I dual-mine two GPU coins instead? You can mine one GPU coin at a time per card; the efficient pairing is a GPU coin plus a CPU coin, because they use different hardware. Two GPU coins would just split one GPU.

Do I need a powerful CPU? No, but a stronger multi-core CPU earns more Monero. Even a modest CPU adds something while your GPU does the heavy lifting on its coin.
