Undervolting breaks this cycle. By feeding the chip only the voltage it actually needs (often 1.050V to 1.100V), you lower temperatures by 10-15°C. Lower temperatures allow the GPU to maintain its maximum boost clock for longer periods. 6800xt undervolt settings work
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 | Metric | Stock (1
