6800xt Undervolt Settings Work [new]

Stuttering occurs when the minimum and maximum GPU frequencies are too far apart, causing the card to constantly shift power states. Ensure your minimum clock frequency remains within 100 to 150 MHz of your maximum clock speed to stabilize frame delivery.

Use 3DMark Time Spy or Superposition to test stability.

To undervolt, use the under the "Performance" > "Tuning" tab. Recommended Value Voltage 1025 mV – 1075 mV Stock is usually 1150 mV. Try dropping in 25 mV increments. Max Frequency 2300 – 2450 MHz

You cannot ignore memory tuning when asking if undervolt settings work. The Infinity Cache on the 6800XT loves low latency. 6800xt undervolt settings work

Less heat and lower voltage put less degradation strain on the VRMs and GPU core.

Increase the Power Limit slider to +5% . This prevents the card from throttling during intense rendering spikes.

Less heat means the card hits its thermal ceiling less often, resulting in higher, more stable boost clocks rather than aggressive throttling. Stuttering occurs when the minimum and maximum GPU

Change the Voltage slider from 1150 mV to 1050 mV .

You applied 1075mV and your screen went black. Does this mean undervolting doesn't work? No. It means your specific chip needs a tiny bit more juice.

0% (or +15% to prevent power limits from clipping boost clocks) The "Free Performance" Profile (Mild Overclock + Undervolt) To undervolt, use the under the "Performance" > "Tuning" tab

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.

Run 3DMark Time Spy or Superposition back-to-back three times. Watch for hitching, black screens, or visual artifacts.

The AMD Radeon RX 6800 XT is a powerful graphics card that offers exceptional performance for 1440p and 4K gaming. However, like many high-performance GPUs, it can also be a power-hungry beast, consuming more electricity than necessary to deliver smooth frame rates. This is where undervolting comes in – a technique that allows you to reduce the voltage supplied to the GPU, resulting in lower power consumption, reduced temperatures, and potentially, increased performance.
