: Decreases fan speeds due to lower thermal output.
Regardless of the model, the physics remain the same: Lower voltage equals lower temperature. Lower temperature equals higher sustained FPS. 6800xt undervolt settings work
AMD Adrenalin resets tuning profiles to stock values if the system detects an improper shutdown or a driver timeout. To prevent loss of progress, export your working configuration profile as an .xml file using the save icon in the top-right corner of the tuning menu. Black Screens and Hard Crashes

Let’s look at data from a standard reference 6800XT running Call of Duty: Modern Warfare II at 1440p Ultra.
is widely considered one of the most "undervolt-friendly" cards in recent years. By reducing the voltage, you can significantly lower power consumption and heat without losing performance—and in many cases, you actually gain performance by allowing the card to maintain higher boost clocks for longer. Lower temperature equals higher sustained FPS
Unlocking Efficiency: Do 6800XT Undervolt Settings Work? (2026 Guide)
Repeat this loop until the benchmark crashes or your PC restarts. Once it crashes, you have found your baseline limit. Reopen the software and raise the voltage by to guarantee day-to-day stability. Fine-Tuning Memory and Power Limits
