6800xt Undervolt Settings Work -

Your voltage is too low for the set frequency. Increase the voltage by +10 mV (e.g., from 1050 mV to 1060 mV) and try again.

Here are the settings that consistently work for the 6800 XT, along with a guide on how to apply them safely using AMD Adrenalin Software.

Undervolting the AMD Radeon RX 6800 XT reduces power draw and temperatures while often keeping near-stock performance. Aim: improve efficiency (higher performance-per-watt) and thermals with stable settings for typical silicon. Results vary by card, cooler, and workload.

Example settings:

If you encounter these issues while playing demanding modern titles, simply open AMD Software and raise your voltage by . Conclusion: A Must-Do Tweak

By finding the right undervolt settings, you can lower your card's power draw by 30 to 50 watts, drop temperatures by 5°C to 10°C, and allow the GPU to sustain higher boost clocks for longer periods.

If your card passes the initial test at 1075 mV, go back into the Radeon software and drop the voltage by another 10 mV to 25 mV (e.g., to 1050 mV). Repeat the testing process. Continue this cycle until a game or benchmark crashes. Once it crashes, back up by 15 mV to find your card's personal, rock-solid "sweet spot." Real-World Expected Results

Does it work? Yes. You aren't "underclocking." You are "optimizing efficiency." Your voltage is too low for the set frequency

Sometimes, a GPU will pass heavy benchmarks but crash when transitioning out of a game back to the Windows desktop. Leave your system idling for 10 minutes after a gaming session to test this.

AMD Adrenalin resets tuning profiles to stock values if the system detects an improper shutdown or a driver timeout. To prevent loss of progress, export your working configuration profile as an .xml file using the save icon in the top-right corner of the tuning menu. Black Screens and Hard Crashes

GPUs operate on a voltage-frequency curve. At a given frequency, the graphics card requires a specific amount of voltage to remain stable. AMD's stock settings lean heavily on the side of caution, pushing more voltage than necessary into the silicon.

Before applying any settings, it is vital to understand the concept of the silicon lottery. No two GPU chips are identical. One 6800 XT might run flawlessly at a deeply dropped voltage of 1025mV, while another identical model from the same brand might crash at anything below 1100mV.
