The question of whether to dual mine Ethereum and Zcash is a recurring one among cryptocurrency miners. This practice involves simultaneously mining two different cryptocurrencies, aiming to maximize hardware utilization and potential profits. While technically feasible, the profitability and efficiency of such a strategy depend on a variety of factors, including hardware capabilities, electricity costs, and the current market conditions for both currencies.

Understanding Hash Rates and Algorithms
When discussing mining performance, hash rate is a crucial metric. It represents the speed at which a mining rig can perform calculations. For instance, a hash rate of 65.6 MH/s across three cards equates to approximately 21.9 MH/s per card. This is often compared to the performance of specific GPUs, like the NVIDIA GTX 1070 or 1080. It’s important to note that different cryptocurrencies utilize different hashing algorithms. Ethereum, for example, uses Ethash, while Zcash employs Equihash. The hash rates achieved on one algorithm do not directly translate to another, which can sometimes lead to confusion or inflated perceived performance if not properly accounted for.
A hash rate of 7482 MH/s for 6x 1070s on a specific algorithm (e.g., -dcri 4) translates to about 1,247 MH/s per card. A 1080 might offer a marginally better performance at 1,353 MH/s. However, the significant price difference between these cards (the 1080 often costing considerably more than the 1070) can negate the slight performance advantage, making the 1070 a more cost-effective choice for many miners.
Dual Mining Considerations
The feasibility of dual mining Ethereum and Zcash hinges on several key aspects:
- Hardware: The effectiveness of dual mining is directly tied to the capabilities of your graphics processing units (GPUs). More powerful GPUs can handle the computational demands of two algorithms simultaneously, though they may still have limitations.
- Algorithms: As mentioned, different coins use different algorithms. Successfully dual mining requires hardware that can efficiently process both.
- Profitability: The ultimate goal is to increase earnings. This involves calculating the potential revenue from both currencies against the costs of electricity and hardware depreciation.
- Software and Configuration: Specialized mining software is required to manage the process. Inputting correct values for hash rates and other parameters is critical to avoid inflated or inaccurate profit calculations.
It’s also worth considering that specialized hardware, such as ASICs (Application-Specific Integrated Circuits), are designed for mining specific algorithms and can often outperform GPUs in terms of efficiency and hash rate for those particular coins. However, ASICs are typically less versatile and cannot be used for dual mining different types of coins in the same way GPUs can.
Maximizing Profitability
To achieve optimal results when dual mining Ethereum and Zcash, miners should:
- Utilize Reliable Data: Source hash rate and profitability data from reputable mining pools and calculators.
- Understand Algorithm Differences: Be aware that hash rates are algorithm-specific and do not directly transfer between different coins.
- Continuously Optimize: Regularly review and adjust mining settings, including overclocking and undervolting, to balance performance and power consumption.
- Monitor Market Prices: Stay informed about the fluctuating market prices of both Ethereum and Zcash, as this directly impacts profitability.
While dual mining Ethereum and Zcash can be a profitable venture, it requires careful planning, accurate calculations, and ongoing management. By implementing the right strategies and staying informed, miners can potentially enhance their earnings through this method.
