6800xt Undervolt Settings Work [new] Jun 2026

Run a benchmark at 100% stock settings. Note your score, max junction temperature, and average clock speeds.

If you have a high-quality chip (like the Sapphire Nitro+ or PowerColor Red Devil), you can push further: 1000 mV – 1025 mV. 6800xt undervolt settings work

: Continue until the benchmark crashes. Once it does, go back up by 15–20 mV to ensure "rock-solid" stability for daily gaming. Run a benchmark at 100% stock settings

The RX 6800 XT is a powerhouse, but it comes with a trade-off: heat and power draw. Out of the box, AMD pushes these cards to their limits, often resulting in fan curves that sound like a jet engine taking off. : Continue until the benchmark crashes

Graphics card manufacturers apply a generous voltage cushion to every GPU chip. This ensures stability across a wide variance of silicon quality (the "silicon lottery").
