Undervolt Settings Work |link| — 6800xt

Undervolting the Radeon RX 6800 XT effectively reduces power draw and heat—often improving sustained performance by avoiding thermal throttling—without significantly impacting clock speeds

2. Why Undervolting Works on Navi 21

• Factory voltage excess: AMD sets conservative voltages (1.150V–1.200V) to guarantee stability across all silicon qualities. Most 6800 XT chips are stable at 1.025V–1.075V at stock clocks.
• Power-limited architecture: Lower voltage reduces current draw, allowing the GPU to hit frequency limits longer before hitting power limits.
• Thermal headroom: Lower temperatures reduce leakage current and allow boost algorithm to stay active.

Undervolting is the process of reducing the voltage supplied to a GPU, CPU, or other electronic component, while maintaining or even increasing its performance. By lowering the voltage, you can decrease power consumption, heat generation, and noise levels, making your system more efficient, quiet, and environmentally friendly. 6800xt undervolt settings work

Min Frequency: Set this 100 MHz lower than your Max Frequency to keep clock speeds consistent. Undervolting the Radeon RX 6800 XT effectively reduces

Disclaimer: Undervolting is generally safe because you are reducing voltage (not increasing it). However, crashes can cause data loss. Always save your work before stress testing. The author assumes no liability for aggressive tuning. Factory voltage excess: AMD sets conservative voltages (1

At this voltage, the card draws around 300W to 330W under full load. This generates significant heat. When the GPU hits 85°C or higher (or a Junction/Hotspot temp of 105°C+), the boost algorithm panics. It starts dropping clocks aggressively to save the silicon.
