How to dual mine ETH and RVN with T-Rex?

In this guide we will show you how to set up dual mining of Ethereum and RVN on minerstat with your LHR cards. Keep in mind that this tutorial required GPUs with 8 GB VRAM or more for msOS and 10 GB VRAM or more on Windows.

About dual mining In dual mining two coins are mined at the same time at different pools of your choosing. The coins don't have to be of same algorithm, but to be able to dual mine, your mining client needs to support dual mining.

1. Pools

First, open the address editor and add a new tags (POOL:ETH) which will hold ETH stratum address and (POOL:RVN) will hold the RVN stratum address. In this example, we will use Ethermine and 2Miners:

  • ETH: stratum+tcp://
  • RVN: stratum+tcp://

4. TREX config

Click on [Advanced] tab and update the mining client's configuration so that it will be defined as:

"pools": [
"user": "(WALLET:ETH)⁣.(WORKER)",
"worker": "(WORKER)⁣",
"url": "(POOL:ETH)⁣",
"pass": "x"
"no-nvml": false,
"api-bind-http": "",
"json-response": true,
"retries": 3,
"retry-pause": 5,
"timeout": 500,
"algo": "ethash",
"lhr-algo": "kawpow",
"user2": "(WALLET:RVN).(WORKER)",
"url2": "(POOL:RVN)",
"pass2": "x",
"exit-on-cuda-error": true,
"exit-on-connection-lost": false
