The Rise of Cryptocurrency Mining
The 2017 global Bitcoin ransomware attack ("Eternal Blue") reignited interest in cryptocurrency markets, causing significant price surges across major coins including Ethereum, Litecoin, and Zcoin. This mining resurgence created unprecedented demand for graphics cards, leading to widespread shortages and price inflation.
Mining PC Hardware Essentials
Core Components Overview
| Component | Recommendation | Notes |
|---|---|---|
| CPU | Intel Celeron G3900/G3930 | Entry-level dual-core sufficient |
| GPU | GTX 1060 3G/RX470 or better | Prioritize Samsung memory chips |
| RAM | 4GB DDR4 | Minimal system requirements |
| Storage | 120GB SSD | Avoids HDD heat/mechanical issues |
| Motherboard | Gigabyte H110-D3A | Supports 6+ GPUs via PCIe extensions |
| PSU | 1250W+ Full Modular | Accommodates multi-GPU power needs |
Critical Mining Considerations
GPU Selection:
- AMD RX 470/580 and NVIDIA GTX 1060+ offer best price/hashrate ratios
- Professional mining cards (no display outputs) provide higher efficiency
Thermal Management:
- Custom open-air mining frames recommended
- Maintain minimum 3-inch GPU spacing
- Supplemental case fans crucial for 24/7 operation
Infrastructure:
- PCIe 1X-to-16X riser cards required (buy 20% extra for failures)
- Well-ventilated location mandatory
GPU Hashrate Performance Table
| Model | Ethereum Hashrate (MH/s) | Power Draw (W) |
|---|---|---|
| GTX 1060 3G | 18 | 120 |
| RX 470 | 20 | 150 |
| GTX 1070 | 25 | 150 |
| RX 580 | 22 | 185 |
Pro Tip: Overclocking GPUs can yield 10-15% higher hashrates, but requires careful thermal monitoring.
Optimizing Your Mining Rig
👉 Essential mining equipment checklist
- Memory Selection: Samsung GDDR5 chips demonstrate 5-8% better performance
- Power Efficiency: Calculate total system draw (GPUs x TDP + 100W overhead)
- Maintenance: Blow dust monthly, replace thermal paste annually
Frequently Asked Questions
What's the ROI timeframe for Ethereum mining?
With current difficulty levels and ETH prices, most rigs break even in 8-12 months. Factors include electricity costs, hardware efficiency, and cryptocurrency market volatility.
How many GPUs can one motherboard support?
Specialized mining boards support 6-12 GPUs via PCIe risers. The Gigabyte H110-D3A in our guide handles 6 cards optimally.
Is liquid cooling better for mining rigs?
Generally not recommended. Air cooling with open frames provides better reliability and lower maintenance for 24/7 operation.
Should I buy used mining GPUs?
Exercise extreme caution. Mining cards often have degraded memory from continuous thermal cycling. Request benchmark tests and warranty verification.
