Keeping the minimum frequency within 100–150 MHz of the maximum frequency stabilizes the clock state transitions, preventing aggressive micro-stutters. Increasing the power limit gives the card headroom to maintain these clocks, while the 1075 mV cap keeps heat in check. 2. The Aggressive Sweet Spot Settings (70% Success Rate)
Most RX 6800 XT cards ship with a stock voltage of , which is often higher than necessary for stability. Undervolting allows you to:
Because AMD’s boost algorithm (Precision Boost Overdrive/RDNA2 telemetry) is highly sensitive to thermal headroom, lowering the temperature often allows the card to sustain its maximum boost clocks for longer periods. The Real-World Benefits 6800xt undervolt settings work
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.
Note: Every GPU has different "silicon lottery" results. These settings are a baseline. Some users report stability as low as 1020mV, while others require 1060mV–1070mV. 1. The "Safe & Cool" Baseline Keeping the minimum frequency within 100–150 MHz of
Undervolting is generally safe because you are reducing voltage (not increasing it). However, crashes can cause data loss. Always save your work before stress testing. The author assumes no liability for aggressive tuning.
Counterintuitively, a successful undervolt often results in higher or more consistent clock speeds. Look at your frequency graph. If the line is flat and hovering near your target clock rather than fluctuating wildly, the undervolt is doing its job.

The best tool for this is the official AMD Adrenalin software. Open Adrenalin, go to the tab, then Tuning . Set Tuning Control to Manual .

Undervolting—the process of reducing the voltage supplied to the GPU while maintaining its clock speed—is the definitive way to tame this card. Here is a deep dive into whether 6800 XT undervolt settings actually work, how much performance you gain, and the exact settings to use. Do 6800 XT Undervolt Settings Work?
