Undervolt Settings Work - 6800xt

You will see forum posts saying: "My 6800XT runs at 2500Mhz @ 1000mV, you just have a bad chip."

These users are lying or only ran Furmark for 30 seconds. True stability requires testing three distinct workloads:

If you pass all three, your settings work. If you only pass Time Spy, your settings are fragile.

| Setting | Conservative (Safe) | Aggressive (Max Performance) | | :--- | :--- | :--- | | Voltage (mV) | 1050 mV | 980 mV - 1000 mV | | Max Frequency | 2100 MHz | 2200 MHz - 2300 MHz | | Min Frequency | 500 MHz (Leave stock) | 2400 MHz (Memory OC usually required) | 6800xt undervolt settings work

Undervolting the AMD Radeon RX 6800 XT consistently reduces power consumption (15–25%) and operating temperatures (5–10°C lower) while maintaining 97–100% of stock performance. In many cases, properly tuned undervolts improve clock stability, leading to higher sustained boost clocks than stock. This report confirms that undervolting works effectively for this GPU.

Yes — undervolt settings on the RX 6800 XT work reliably and are strongly recommended.

End of report.

Undervolting the Radeon RX 6800 XT can significantly reduce power consumption and heat while maintaining—or even improving—performance through better thermal headroom Recommended Undervolt Settings

While "silicon lottery" means every card varies, most users find stability within these ranges: 1025 mV to 1075 mV (Stock is typically 1150 mV). Max Frequency: 2350 MHz to 2500 MHz. Min Frequency:

Set this roughly 100 MHz below your Max Frequency (e.g., 2300 MHz) for consistent performance. VRAM Tuning: Fast Timing and set frequency to 2100–2150 MHz. Power Limit: Increase to You will see forum posts saying: "My 6800XT
