GPU Miners: Undervolt to reduce power usage and heat by 10%-20% In this insightful YouTube video titled "GPU Miners: Undervolt to reduce power usage and heat by 10%-20%," Lee from IM Blocks shares practical strategies for optimizing GPU mining efficiency. Through undervolting, miners can reduce both power consumption and heat production, leading to significant savings in electricity and a cooler operating environment.

Key Takeaways​

1. Understanding Undervolting: Lee explains that undervolting involves lowering the voltage supplied to the GPU while maintaining performance levels. This process can effectively cut power usage by 10% to 20%, which is crucial for high-performance graphics cards like the RX470, particularly under mining loads.
2. Step-by-Step Guide:
   • The video begins with an overview of current power draw metrics, noting that the RX470 typically operates at around 138-140 watts during dual mining.
   • Lee utilizes software tools to adjust the GPU voltage incrementally, recommending a reduction of about 25 millivolts (mV) to start.
   • Throughout the demonstration, he monitors the impact on power draw and temperature, finding that after undervolting, the GPU’s power consumption can drop below 100 watts.
   []Temperature Management: One of the compelling benefits of undervolting, aside from energy efficiency, is the reduction in heat output. In the demo, he shows a decrease in GPU temperatures from 73°C to 68°C, highlighting how undervolting also leads to less fan noise and a more stable mining operation. []Testing and Safety: Lee emphasizes the importance of testing stability after adjusting settings. If any crashes or graphical glitches occur, users are advised to revert to default settings or make smaller voltage adjustments until an optimal balance is achieved.
3. Community Insight: The video fosters a sense of community among miners by encouraging experimentation and sharing results. Lee mentions that many users have achieved even lower power draw levels, down to 70-75 watts on the RX470, showcasing the variability and potential of undervolting.
