Lower temps allow fan curves to run at lower RPMs.
However, using MPT carries more risk and can be complicated, often requiring you to edit and flash custom registry files. If this is your first time undervolting, the Adrenalin Software method is more than sufficient to see massive benefits.
While every single GPU chip behaves differently, community testing across hundreds of Big Navi cards has established a reliable baseline. Use the AMD Software: Adrenalin Edition to apply these values. The Balanced Blueprint (Best for Most Users) 2300 MHz Max Frequency: 2400 MHz Voltage: 1050 mV (Stock is usually 1150 mV) Memory Tuning: Enabled (Fast Timing, 2100–2150 MHz) Power Limit: +15%
Run Time Spy Stress Test + 20 minutes of Cyberpunk’s built-in benchmark. If no crash, drop voltage by 10 mV and repeat. Stop at 1020 mV or first crash—then add back 15 mV for daily stability. 6800xt undervolt settings work
You might find a setting that appears stable in benchmarks like FurMark, but your actual gaming performance is terrible. You are likely experiencing a phenomenon called .
: Lower the Voltage slider to 1075 mV and hit "Apply".
Undervolt settings work , but not every game plays nice. The 6800 XT’s RDNA2 architecture is voltage-sensitive across different workloads: Lower temps allow fan curves to run at lower RPMs
: Open AMD Adrenalin, go to the Performance tab, then select Tuning .
To complement your undervolt, adjust these secondary settings:
: Reduces core and junction temperatures by 5°C to 15°C. While every single GPU chip behaves differently, community
Since you are generating less heat, you can run fans slower for a quieter PC, or keep them high for max cooling.
You need a reliable way to test stability and log your baseline metrics. Download or Superposition , alongside HWMonitor or HWInfo64 to track temperatures. Step 2: Establish a Baseline
Drop the voltage slider from the stock 1150 mV down to for your first test iteration. 4. Adjust Power and Memory
