  • Lower Power Limit to 80–90% and leave voltage curve alone. This reduces power draw and can keep clocks similar due to better boost behavior.
  • Test performance drop; many users see <2–5% loss with 15–20% power reduction.

Power Limit:

Increasing the power limit to +15% is recommended to ensure the card isn't artificially throttled while you are testing for voltage stability. 6800xt undervolt settings work

  • Draft a full-length paper (introduction, methods, detailed results table, charts, references, sample test logs) tailored to academic or enthusiast audiences.
  • Or produce a one-page printable guide with step-by-step screenshots for Radeon Software or MSI Afterburner.

Voltage:

For most users looking for a balance of lower heat and rock-solid performance, these settings are widely reported as a reliable starting point. (Stock is typically Max Frequency: Min Frequency: Set to lower than your Max Frequency (e.g., ) to maintain consistent frame times. Power Limit: RX 6800 XT Go to product viewer dialog for this item

1050 mV

Of course, stability is the key challenge. Not every 6800 XT chip is identical; a golden sample might run stable at 990 mV, while an average card may crash below 1040 mV. The most reliable and widely reported working settings involve a three-step process: setting the voltage to , raising the power limit to +15% (to allow transient spikes), and leaving the VRAM frequency at its default 2100 MHz (or a mild 2110 MHz with Fast Timing). Users should then stress test with demanding benchmarks like Time Spy Extreme or games known for voltage sensitivity, such as Red Dead Redemption 2 . If a crash or driver timeout occurs, increasing voltage by 10 mV steps until stable is the standard fix. Lower Power Limit to 80–90% and leave voltage curve alone

  • Min Frequency: 500 MHz (Leave at stock)
  • Max Frequency: 2400 MHz (Often stock is 2250 MHz; raising this slightly prevents the card from power throttling).
  • Voltage (mV): 1050 mV (Stock is usually 1150 mV. This is a 100mV drop).

Enable Manual Mode

: Change Tuning Control to Manual and enable GPU Tuning , Advanced Control , and Voltage .

If you have a model with exceptional cooling (like the Nitro+ or Strix), or if you want to push the efficiency further, try these aggressive settings. Note: This may require a slightly higher fan curve.
