Play demanding games (e.g., Cyberpunk 2077, Metro Exodus, Starfield ) for an hour. If it Crashes: Raise the voltage by ) and test again. Conclusion: Are 6800XT Undervolt Settings Worth It?

Most RX 6800 XT cards ship with a stock voltage of , which is often higher than necessary for stability. Undervolting allows you to:

Because of the "silicon lottery," every card is slightly different, but most 6800 XT owners find stability within these ranges: Standard Stable Range Performance-Focused UV 1050 mV – 1100 mV 1015 mV – 1040 mV Min Frequency 2300 MHz – 2400 MHz 2400 MHz – 2500 MHz Max Frequency 2400 MHz – 2500 MHz 2600 MHz – 2700 MHz VRAM Clock 2000 MHz – 2100 MHz 2100 MHz – 2150 MHz VRAM Timing Fast Timings Power Limit 0% to +15% Step-by-Step Configuration Guide 6800xt undervolt settings work

This article dives into why undervolting works, provides actionable, stable settings, and explains how to test your 6800 XT for maximum efficiency. Why Undervolt the RX 6800 XT?

Undervolting works by finding the lowest voltage required for your specific card to operate stably at a desired frequency. Play demanding games (e

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

Here is a real-world example of the gains one user saw:

It is important to note that "6800xt undervolt settings work" differently depending on your specific model.

When you undervolt, you trim away this excess voltage. Because the chip runs cooler, AMD's Radeon Boost algorithms can maintain higher frequencies for longer durations before hitting thermal throttles. You end up with a card that is quieter, consumes 30 to 50 watts less power, and performs identically to—or better than—stock settings. The Best Baseline Undervolt Settings
