Set to 2100–2150 MHz with "Fast Timings" enabled for a small performance boost.
Boot up a graphically intense game. Play for 30 to 60 minutes. Look out for micro-stutters, driver timeouts, or hard crashes to the desktop.
Play demanding games (e.g., Cyberpunk 2077, Starfield) for at least 30 minutes.
If your PC force-reboots or crashes, AMD Adrenalin will reset your performance tuning to factory defaults. This is a safety feature. To avoid losing your progress, use the button in the top right of the tuning menu to save your stable configurations to a file on your desktop. Game-Specific Instability

Set the Power Limit to maximum (+15%) to allow the card flexibility for stability.
Every 6800 XT is different (the "silicon lottery"), but most cards can handle a significant reduction. ≈1150mV - 1200mV
The best tool for this is the official AMD Adrenalin software. Open Adrenalin, go to the tab, then Tuning . Set Tuning Control to Manual .
Set this roughly 100 MHz below your Max Frequency (e.g., 2300 MHz) for consistent performance. VRAM Tuning: Fast Timing and set frequency to 2100–2150 MHz. Power Limit: Increase to Set to 2100–2150 MHz with "Fast Timings" enabled
Increase fan speeds slightly to keep the card cooler, allowing the voltage to stay low. Test Stability: Run a 3DMark stress test. If it crashes: Raise the voltage by 10mV and try again.
Stuttering occurs when the minimum and maximum GPU frequencies are too far apart, causing the card to constantly shift power states. Ensure your minimum clock frequency remains within 100 to 150 MHz of your maximum clock speed to stabilize frame delivery.

The AMD Radeon RX 6800 XT is a powerhouse of a graphics card. Built on the RDNA 2 architecture, it delivers exceptional 1440p and 4K gaming performance. However, out of the box, many cards run hotter and draw more power than necessary. Look out for micro-stutters, driver timeouts, or hard
Because every GPU is different ("silicon lottery"), you should use these community-tested ranges as a starting point within the software.
Every individual GPU behaves differently due to manufacturing variances. However, the RX 6800 XT community has established reliable baseline settings that serve as an excellent starting point for most cards. Stock vs. Target Settings 1150 mV Safe Target Undervolt: 1025 mV to 1075 mV Aggressive Target Undervolt: 1000 mV to 1025 mV Recommended Starting Profile
Because the card runs cooler, your fan curve can be flattened, resulting in a significantly quieter gaming PC.
