| Metric | Stock (1.150V) | Undervolt (1.075V) | Change | | :--- | :--- | :--- | :--- | | | 138 fps | 150 fps | +12 fps | | GPU Power Draw | 312W | 258W | -54W | | GPU Hotspot Temp | 104°C | 88°C | -16°C | | Fan Noise | 2,400 RPM (Loud) | 1,600 RPM (Quiet) | -33% |
As you can see, the undervolted settings result in similar performance, but with significantly reduced power consumption and temperatures.
Undervolting the Radeon RX 6800 XT is widely considered the most effective way to optimize the card, as it can reduce power draw by up to and lower junction temperatures from with minimal performance loss. Recommended 6800 XT Undervolt Settings 6800xt undervolt settings work
By finding the right undervolt settings, you can lower your card's power draw by 30 to 50 watts, drop temperatures by 5°C to 10°C, and allow the GPU to sustain higher boost clocks for longer periods.
The stock RX 6800 XT typically runs at a maximum voltage of 1150 millivolts (mV). A stable undervolt aims to drop this value while maintaining stable clock speeds.

Disable "Zero RPM" mode if you prioritize thermal longevity. Create a progressive curve that hits 65% fan speed when the GPU Hot Spot reaches 85°C. The Stability Testing Methodology
If the driver crashes or the game closes, increase your voltage by 10 mV increments until stable. Conclusion Undervolting your
Lower heat allows for a less aggressive fan curve, reducing system noise. The stock RX 6800 XT typically runs at
GPU edge temperatures generally drop by 5°C, while the critical Hotspot/Junction temperature can plummet by 10°C to 15°C.
