Ethereum: Better or Worse to Mine Multiple Workers on a Single Machine?

As a cryptocurrency enthusiast and miner, you are probably familiar with the process of running multiple mining rigs on your computer. In this article, we will find out whether it is better or worse to mine multiple workers on a single machine using different mining software.

What is CGMiner?

CGMiner is a popular mining software that allows users to install and run multiple instances of the mining algorithm on their computer. This setup is commonly used in cryptocurrency mining pools to increase the overall hashing power and earn more from each coin mined.

The Scenario: Running Multiple Instances of CGMiner on a Single Machine

Let’s say you have a computer with an Intel Core i5 processor, 8GB of RAM, and an NVIDIA GeForce GTX 1060 graphics card. You are using Ubuntu 12.10 as your operating system and you want to set up multiple instances of CGMiner to mine Bitcoin (BTC) in the 50 BTC pool.

Three-worker setup

You create three separate instances of CGMiner:

Worker #1: Mining on CPU

Worker #2: Mining on GPU (GeForce GTX 1060)

Worker #3: Mining on CPU (again, for redundancy)

The question: which is better or worse?

In this setup, you are essentially mining Bitcoin using three different algorithms:

CPU (on worker #1): Mining SHA-256 algorithm

GPU (GeForce GTX 1060) (on worker #2): Mining SHA-256 and Scrypt (for Ethereum) algorithms

CPU (again, on worker #3): Mining the same SHA-256 algorithm

Benefits of running multiple workers

Running multiple workers has several advantages:

Increased hash power: With three instances running together, you can significantly increase your overall hash rate and earn more from each coin mined.

Improved profitability

: By spreading costs across multiple rigs, you can potentially reduce your electricity bill and increase your profitability.

Disadvantages of running multiple workers

However, there are also some disadvantages to consider:

Increased complexity: Running multiple workers requires more setup, monitoring, and maintenance than a single setup.

Potential overheating: With multiple GPUs or CPU cores running simultaneously, you may experience overheating issues, especially if your computer is not properly cooled.

Limited profitability: If the pool payout per block remains constant, it is possible that running multiple workers will result in lower profit margins compared to a single setup.

Conclusion

In conclusion, running multiple workers on a single machine can be beneficial for increasing hash rate and earning more from each coin mined. However, it also comes with added complexity and potential drawbacks. Ultimately, the decision to run multiple workers depends on your specific mining setup, pool payout, and personal preference.

If you are already using CGMiner and have a reliable power supply and cooling system, running three instances may be a good option for you. However, if you are new to cryptocurrency mining or are unsure of the costs involved, it is recommended to start with a single setup and gradually expand it as needed.

Recommendation

To minimize potential drawbacks and maximize benefits, consider the following:
