This guide provides a comprehensive overview of using NVIDIA's GTX 1660 and 1660 Super graphics cards for building a cryptocurrency mining operation. We'll cover their performance, profitability factors, and key considerations for both new and experienced miners.
Understanding the GTX 1660 for Mining
The NVIDIA GeForce GTX 1660 series, particularly the 1660 Super variant, has established itself as a reliable choice for cryptocurrency mining. These cards offer a balance between initial investment, power consumption, and mining performance that makes them attractive for specific algorithms.
Based on the Turing architecture, these GPUs provide efficient performance for certain mining algorithms without the premium cost associated with higher-end RTX models. Their 6GB of GDDR6 memory (on the Super model) is sufficient for many popular cryptocurrencies.
Key Performance Metrics
When evaluating GTX 1660 mining rigs, several performance metrics deserve attention:
- Hash Rate: The 1660 Super typically delivers approximately 30-32 MH/s on the Ethash algorithm (Ethereum Classic) when properly optimized
- Power Consumption: A single card generally draws between 75-90 watts when tuned for mining efficiency
- Efficiency Ratio: This combination results in an efficiency of around 0.35-0.40 MH per watt, which is competitive in its class
- Thermal Performance: These cards typically operate at temperatures between 50-65°C with adequate cooling
Building a Multi-GPU Mining Rig
A standard mining configuration often utilizes multiple GPUs to maximize output. Common setups include:
4-GPU Configuration: A balanced approach for beginners, offering manageable power requirements and heat output.
6-GPU Configuration: Provides increased hashing power while still maintaining reasonable infrastructure demands.
8-GPU Configuration: Maximizes output from a single mining frame but requires robust power delivery and cooling solutions.
Each additional GPU increases both computational power and the demands on your supporting infrastructure—particularly power supply capacity and cooling effectiveness.
Essential Mining Rig Components
Beyond the graphics cards themselves, a functional mining operation requires several key components:
- Motherboard: Specifically designed with multiple PCIe slots for GPU mining
- Power Supply Unit (PSU): High-wattage, efficient units (800W-2000W depending on GPU count) with adequate PCIe connectors
- Mining Frame: Open-air frame to ensure proper airflow and cooling
- CPU and RAM: Basic specifications are sufficient since mining primarily relies on GPU power
- Storage: SSD preferred for faster boot times and reliability
- Operating System: Typically Linux-based mining OS or Windows with mining software
Economic Considerations
The financial aspect of mining involves several variables:
Initial Investment: The cost of hardware, which varies based on GPU availability and market conditions.
Operational Costs: Primarily electricity consumption, which directly impacts profitability.
Cryptocurrency Market Conditions: Coin values and mining difficulty significantly affect potential returns.
Maintenance and Upkeep: Factor in occasional component replacement and system maintenance.
Before investing in mining equipment, carefully research current market conditions and calculate potential return on investment based on your specific electricity costs. 👉 Explore mining profitability calculators
Cooling and Maintenance Strategies
Proper thermal management is crucial for mining hardware longevity and efficiency:
- Airflow Optimization: Position rigs in well-ventilated areas with adequate space between components
- Environmental Control: Maintain ambient temperatures below 25°C (77°F) for optimal performance
- Regular Maintenance: Clean dust filters and components periodically to prevent overheating
- Undervolting: Reduce power limits while maintaining hash rates to decrease heat output
Frequently Asked Questions
What cryptocurrencies are most profitable to mine with GTX 1660 cards?
The GTX 1660 performs well with Ethereum Classic (ETC), Ravencoin (RVN), and Conflux (CFX). Profitability changes constantly based on market conditions and network difficulty, so regular monitoring is essential.
How long does a GTX 1660 typically last in a mining operation?
With proper cooling and maintenance, these cards can operate effectively for 3-5 years. Thermal management and power stability are the primary factors determining lifespan in continuous operation.
What is the power requirement for an 8-card GTX 1660 mining rig?
An 8-GPU rig typically requires a 1600-2000W power supply, accounting for the GPUs, motherboard, and other components. Always allow a 20% overhead beyond calculated maximum draw.
Can GTX 1660 mining be profitable with high electricity costs?
Profitability diminishes significantly as electricity rates exceed $0.15-$0.18 per kWh. Calculate your specific break-even point using online mining calculators before investing in equipment.
What software is needed to operate a mining rig?
You'll need mining software like T-Rex, PhoenixMiner, or NBminer, a cryptocurrency wallet, and potentially monitoring software to track performance and temperatures remotely.
How does the mining profitability of the 1660 Super compare to the RTX 3060?
While the RTX 3060 offers higher hash rates (approximately 45-50 MH/s), the 1660 Super often provides better efficiency per dollar invested initially. The choice depends on your budget and electricity costs.
Conclusion
The GTX 1660 series, particularly the Super variant, represents a solid entry point into cryptocurrency mining for those seeking a balance between performance and investment. While not the most powerful option available, these cards offer respectable efficiency and have proven durable in mining operations.
Success in cryptocurrency mining requires careful planning, ongoing monitoring of market conditions, and proper hardware maintenance. As the market evolves, staying informed about algorithm changes and new mining opportunities will help maximize your investment's potential.
