Advantages of Overclocking Mining Machine：

1. Increased Hashrate → Increased Profit: Overclocking directly increases hash rate, resulting in higher output and higher daily profits in the short term.

2. Shortened Payback Period: Increased profit per unit time accelerates the payback period.

3. Enhanced Competitiveness: Gaining an advantage during periods of rising network difficulty or intense mining competition, allowing you to capture a larger market share.

4. Higher Resource Utilization: Unleashing the full potential of hardware, especially effective for equipment with conservative performance settings.

5. Adjustable to Adapt to Market/Electricity Prices: Dynamic frequency adjustment based on coin prices, electricity costs, or cooling conditions allows for flexible operations.

6. (Can be combined with voltage reduction) Improved Energy Efficiency: Appropriate overclocking and voltage reduction can sometimes improve hashrate while optimizing J/T performance, thereby increasing revenue per watt.

Advantages of Overclocking Mining Machine：

1. Reduced Power Consumption: Frequency downscaling can significantly reduce power consumption and lower electricity costs, making it particularly suitable for areas with high electricity prices.

2. Reduced Heat: When the frequency is reduced, the chip temperature drops, helping to improve the cooling environment of the mining machine and extend the hardware life.

3. Improved Stability: In high-temperature environments or when the voltage is unstable, frequency downscaling can reduce problems such as freezes, board failures, and hashrate fluctuations.

4. Extended Service Life: Reduced operating pressure reduces wear and tear on hardware such as chips and fans, extending the overall lifespan.

5. Adaptation to Market Conditions: When coin prices are low and electricity costs are high, frequency downscaling can reduce mining costs and maintain positive returns.

6. Quieter: When power consumption and temperature drop, fan speed also decreases, reducing operating noise.
