What is Dual Mining? Explained with Palit GeForce RTX 4070 Dual 12GB

Dual Mining: A Smarter Way to Mine

Dual mining, or merged mining, means simultaneously mining two different coins using a single graphics card. This allows miners to increase overall profit by efficiently distributing computational resources between two algorithms.

This method became popular in 2017 when mining difficulty was rising, and coin prices were falling. Miners started exploring new approaches to maintain profitability. We'll provide information on current cryptocurrency pairs for dual mining and the features and settings for the Palit GeForce RTX 4070 Dual 12GB graphics card.

Top Cryptocurrency Pairs for Maximum Efficiency in Dual Mining

The popularity of various pairs for dual mining changes over time, depending on network difficulty and cryptocurrency market value. In 2017, miners often combined Ethereum mining with coins like Decred, SiaCoin, or Pascal. However, these combinations gradually lost relevance. In 2022, amid falling cryptocurrency prices, dual mining regained attention. For example, it was profitable to mine ETH along with TON for a while.

However, TON mining ceased in summer 2022, and ETH mining stopped in September 2022. Interest in dual mining was also fueled by the release of Nvidia's new line of graphics cards, which artificially reduced the hash rate of GPUs for mining using the LHR (Low Hashrate) algorithm.

As of early 2025, these dual mining setups offer optimal efficiency, allowing miners to maximize hardware utilization. The table below lists popular coin pairs, their algorithms, and key benefits.

Mining Bitcoin with graphics cards is always unprofitable; it's better to choose alternative coins that can be exchanged for Bitcoin.

How to Start Dual Mining

It's important to understand that different resources of a graphics card are used for calculating the hashing algorithms of various coins. For example, when mining ETC with the Ethash algorithm, the main load is on the graphics card's memory, while its GPU is minimally loaded. Utilizing different GPU resources during mining opens up possibilities for simultaneously mining two or more coins.

To start dual mining, you need good software. Here are the steps to begin dual mining:

1. Choose a suitable graphics card. Ensure your graphics card supports dual mining and has enough power to mine two coins simultaneously
2. Install the necessary software. Download and install software that supports dual mining. One of the most popular programs for dual mining is T-Rex. It's optimized for the mining process, especially with Nvidia cards, and supports many popular algorithms. There's also LoLMiner, which is well-suited for AMD cards and successfully bypasses hash rate limitations on Nvidia cards
3. Configure the miner. Set it up for simultaneous mining of the two selected coins. Specify the pool for each coin, and configure overclocking and power limit parameter
4. Create wallets for each mined coin. This is necessary to receive mining income
5. Monitor and optimize processes. Regularly track system performance, GPU temperature, and overall stability. Adjust settings as needed for optimal efficiency

The efficiency of dual mining depends on algorithm compatibility, hardware capabilities, and current market conditions. Be sure to conduct thorough analysis and testing before starting dual mining.

Exchanges and specialized websites provide calculators and statistics for selecting programs and coins to mine.

After downloading and launching multiple mining programs, you need to configure the .bat file for your rig (graphics cards) and the mined coins.

You can engage in dual mining solo, meaning completely autonomously, but this is unlikely to be profitable. Currently, the most profitable way to dual mine crypto is by joining one of the mining pools. Working in a pool increases the likelihood of receiving rewards.

Optimal Dual Mining Configurations

For optimal dual mining settings, you first need to overclock the graphics card appropriately. The graphics card parameters should support maximum performance and stability. You should also automate cooling processes and reduce load when the system overheats.

Crypto mining programs that allow dual mining usually come with instructions. In almost all such programs, you need to create an executable file with a .bat extension, where the main parameters of dual mining are recorded. This file contains information about the mined coins, mining pools, wallets, etc.

This process is not complicated. All you need to do is replace the variable indicators in the template file with your data.

For effective dual mining, it's recommended to make the following settings:

• Memory overclocking. Increasing memory frequency by 1000-1500 MHz can boost the hash rate when mining coins that require high memory bandwidth
• Reducing power consumption. Setting the power limit to 70-80% helps reduce power consumption and temperature without significant performance loss
• Core tuning. For some algorithms, it's useful to lower the core frequency by 200-300 MHz, making power consumption and heat generation less active
• Temperature control. Ensure adequate system cooling, keeping the GPU temperature below 70°C for stable operation
