Undervolting is the process of reducing the voltage supplied to a GPU, CPU, or other electronic component, while maintaining or even increasing its performance. By lowering the voltage, you can decrease power consumption, heat generation, and noise levels, making your system more efficient, quiet, and environmentally friendly.
Use the Radeon Software Curve Editor or Afterburner voltage/frequency control. This method assumes you want to keep similar clocks with lower voltage. 6800xt undervolt settings work
This guide covers how to safely undervolt your AMD Radeon RX 6800 XT to lower temperatures, reduce fan noise, and often improve performance (by allowing higher sustained boost clocks). Undervolting is the process of reducing the voltage
. While stock voltage is usually 1150 mV, undervolting can significantly reduce temperatures and power draw—often by 40–50W—with minimal impact on performance. Recommended "Starting Point" Settings This method assumes you want to keep similar
Unlike overclocking, undervolting carries zero hardware risk and reduces fan noise significantly. Even if you only drop from 1150 mV → 1080 mV, you’ll shave off 40W and 6°C with no performance loss.
: If your screen flickers or the PC restarts, the voltage is too low. The AMD driver will usually reset to default. Simply increase the voltage by 5–10 mV and re-test.
