Undervolting
Reducing the voltage supplied to a CPU or GPU to lower temperatures and power consumption while maintaining the same clock speeds. Free efficiency gains.
What is undervolting?
Undervolting reduces the voltage supplied to a processor while keeping clock speeds the same. Lower voltage means less power consumption and less heat — which can reduce fan noise, extend component lifespan, and sometimes even improve performance by preventing thermal throttling.
Undervolting is essentially the opposite of overclocking: instead of pushing for more speed, you push for the same speed with less energy. It's one of the most impactful free optimizations you can make to any PC.
Frequently Asked Questions
Is undervolting safe?
Yes. Undervolting cannot damage hardware — worst case, the system becomes unstable and crashes, which you fix by reducing the undervolt. It's safer than overclocking because you're reducing power, not increasing it.
