Lower temperatures mean the GPU can sustain its boost clocks longer without dropping performance to cool down.
If your game crashes to the desktop or resets your PC, your voltage is too low. Re-open Adrenalin, raise the voltage by 10 mV (e.g., from 1050 mV to 1060 mV), and test again. Repeat this until the crashes stop. Expected Results and Benefits
Run UNIGINE Superposition on the "1080p Extreme" or "4K Optimized" preset.
You need the official AMD software to adjust voltage and frequency curves. 6800xt undervolt settings work
Finding the right 6800XT undervolt settings is a game-changer for thermal management and efficiency. By reducing the core voltage, you can significantly drop power consumption and heat—often while maintaining or even improving stock performance. Why Undervolt the RX 6800 XT?
While every single GPU chip behaves differently, community testing across hundreds of Big Navi cards has established a reliable baseline. Use the AMD Software: Adrenalin Edition to apply these values. The Balanced Blueprint (Best for Most Users) 2300 MHz Max Frequency: 2400 MHz Voltage: 1050 mV (Stock is usually 1150 mV) Memory Tuning: Enabled (Fast Timing, 2100–2150 MHz) Power Limit: +15%
Undervolting your 6800 XT is one of the best ways to get better performance, lower temperatures, and higher efficiency in 2026. By setting your voltage to roughly and managing your fan curves, you can keep this card competitive for years to come. Lower temperatures mean the GPU can sustain its
Are you prioritizing or maximum performance ?
Most RX 6800 XT cards ship with a stock voltage of , which is often higher than necessary for stability. Undervolting allows you to:
When you dial in an undervolt that works, the physical changes to your PC environment are immediate: Repeat this until the crashes stop
By reducing thermal throttling, the card can maintain higher clocks longer. Proven 6800 XT Undervolt Settings (2026)
This guide covers how to safely undervolt your AMD Radeon RX 6800 XT to lower temperatures, reduce fan noise, and often improve performance (by allowing higher sustained boost clocks).
| Setting | Conservative (Safe) | Aggressive (Max Performance) | | :--- | :--- | :--- | | | 1050 mV | 980 mV - 1000 mV | | Max Frequency | 2100 MHz | 2200 MHz - 2300 MHz | | Min Frequency | 500 MHz (Leave stock) | 2400 MHz (Memory OC usually required) |
