Set this to 100 MHz below your Max Frequency (e.g., 2300 MHz) to keep clocks stable during gaming.
However, there is an open secret among PC enthusiasts: the 6800XT runs hot, loud, and power-hungry out of the box. The solution isn't liquid nitrogen or a $400 water block. It’s a simple, free tweak called undervolting. But if you’ve spent any time on forums like r/AMD or Overclock.net, you’ve seen the frantic question repeated hundreds of times: “Do 6800XT undervolt settings actually work?” 6800xt undervolt settings work
Unlike overclocking, undervolting carries zero hardware risk and reduces fan noise significantly. Even if you only drop from 1150 mV → 1080 mV, you’ll shave off 40W and 6°C with no performance loss. Set this to 100 MHz below your Max Frequency (e
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. It’s a simple, free tweak called undervolting
can significantly reduce power consumption by up to and drop junction temperatures by 20–30°C with negligible performance loss . While every card is unique due to the "silicon lottery," most stable undervolts for this card fall between 1025 mV and 1075 mV . Recommended "Sweet Spot" Settings
A “100% stable” undervolt in benchmarks often crashes within 10 minutes of ray-traced gaming. For daily use, back off 15–20 mV from your lowest benchmark-stable voltage.
