Undervolting the AMD Radeon RX 6800 XT consistently reduces power consumption (15–25%) and operating temperatures (5–10°C lower) while maintaining . In many cases, properly tuned undervolts improve clock stability, leading to higher sustained boost clocks than stock. This report confirms that undervolting works effectively for this GPU.
To undervolt, use the under the "Performance" > "Tuning" tab. Recommended Value Voltage 1025 mV – 1075 mV Stock is usually 1150 mV. Try dropping in 25 mV increments. Max Frequency 2300 – 2450 MHz 6800xt undervolt settings work
Enable . Set memory timing to Fast Timings and max frequency to 2100 MHz . Undervolting the AMD Radeon RX 6800 XT consistently
For most users, these settings provide a stable starting point that balances power savings with performance: 1050 mV to 1100 mV (Stock is typically 1150 mV). Max Frequency: 2400 MHz – 2500 MHz. To undervolt, use the under the "Performance" > "Tuning" tab
