6800xt Undervolt Settings

AMD ships these cards with high "safety" voltages to ensure every single unit works out of the box, regardless of quality. Most 6800 XTs are over-volted by design. When you trim that excess, the card runs cooler. Because modern GPUs boost their speed based on thermal headroom, a cooler card often stays at its maximum clock speed longer than a hot one, leading to smoother gameplay. Power Limit is Key:

Keep in mind that these are just examples, and you should experiment with different settings to find the optimal balance for your system. 6800xt undervolt settings
