Unlocking the True Potential of RDNA 2: Why 6800XT Undervolt Settings Work (And How to Find Yours)

In this article, we'll explore the world of undervolting the AMD Radeon RX 6800 XT, discussing the benefits, risks, and, most importantly, the optimal undervolt settings that work.

Example safe settings (starting template — adjust per card)

Voltage (mV)

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
