6800xt Undervolt Settings Work |top| Jun 2026

The 6800 XT is voltage-limited, not frequency-limited. By lowering the voltage, you reduce the heat density, allowing the GPU to sustain its boost clocks longer without hitting the thermal or power limits.

slightly higher than stock (e.g., 2400 MHz) for better performance. Memory & Power VRAM Tuning , set it to , and select Fast Timings for a free performance boost. Max out the Power Limit slider (+15%) to give the card breathing room under load. Stress Test : Use benchmarks like 3DMark Time Spy or built-in game benchmarks (like Cyberpunk 2077 6800xt undervolt settings work

Increasing this allows the card to breathe even with lower voltage. Enabled Located in VRAM tuning; provides a "free" performance bump. Step-by-Step Optimization Process The 6800 XT is voltage-limited, not frequency-limited

Does it work? The data proves it. You are getting more performance (because the clock holds steady) using less electricity, with quieter fans. Memory & Power VRAM Tuning , set it

This is the secret weapon that many guides miss. One global undervolt does not work for every game.
