6800xt Undervolt Settings — Work

Why does performance go up with less voltage? Lower voltage reduces thermal throttling and allows the boost algorithm to sustain higher clocks for longer.

A “100% stable” undervolt in benchmarks often crashes within 10 minutes of ray-traced gaming. For daily use, back off 15–20 mV from your lowest benchmark-stable voltage. 6800xt undervolt settings work

Because of the "silicon lottery," every card responds differently. However, these are the most common stable starting points: Profile Type Max Frequency VRAM / Timings 2350 - 2400 MHz 1050 - 1075 mV Stock / Default Balanced (Sweet Spot) 2400 - 2500 MHz 1020 - 1035 mV 2100 MHz / Fast Timings Extreme (High Performance) 980 - 1010 mV 2150 MHz / Fast Timings Why does performance go up with less voltage

Undervolting your RX 6800 XT is a win-win endeavor. It produces a cooler, quieter, and more efficient system that often performs just as well, if not better, than its stock configuration. Start with the stable daily driver settings, test for stability in your favorite games, and then decide if you want to push for more performance or ultimate silence. Your exact mileage will depend on your specific card, but the effort is well worth the reward. For daily use, back off 15–20 mV from

If you crash, increase voltage by 5mV. If you want lower temps, decrease voltage by 5mV until it crashes, then go back up 10mV.

This has led thousands of gamers to explore undervolting. If you are wondering whether 6800 XT undervolt settings actually work, the short answer is yes. When done correctly, undervolting can lower temperatures, reduce power consumption, and even increase your clock speeds.
