: Use stress testing tools like 3DMark Time Spy or OCCT's 3D Adaptive test for at least 10 minutes.
: Lower the voltage slider. Most 6800 XT cards are stable at 1050 mV , but "golden chips" can sometimes reach 950 mV or lower.
: Open AMD Adrenalin, go to the Performance tab, then select Tuning .
: Change Tuning Control to Manual and enable GPU Tuning , Advanced Control , and Voltage .
While every chip varies due to the "silicon lottery," these values are common stable starting points for the AMD Software: Adrenalin Edition : Recommended Value 1025 mV – 1100 mV Start at 1100 mV and work down in 5–10 mV increments. Max Frequency 2350 – 2450 MHz Roughly matches stock boost for maximum stability. Min Frequency 2250 – 2350 MHz Keep this ~100 MHz below your Max Frequency. VRAM Tuning 2100 – 2150 MHz Enable "Fast Timings" for a free performance bump. Power Limit 0% to +15% Higher limits help maintain clocks without throttling. How to Apply Undervolt Settings
Undervolting the Radeon RX 6800 XT is widely considered the most effective way to optimize the card, as it can reduce power draw by up to and lower junction temperatures from with minimal performance loss. Recommended 6800 XT Undervolt Settings
