6800xt Undervolt Settings Work Access

If you want to skip the science and just get into a game, use this baseline profile. It is aggressive enough to matter, but conservative enough to avoid crashing in most DirectX 12 titles.

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

The AMD Radeon RX 6800 XT is a performance beast, but out of the box, it often runs hot and pulls significant power, leading to loud fans and potentially thermal throttling. —reducing the voltage supplied to the GPU while maintaining or increasing clock speeds—is a popular technique to combat this. 6800xt undervolt settings work

You can perform these steps directly within the under the Performance > Tuning tab. How to UNDERVOLT AMD RX 6000 Series GPUs

However, silicon lottery is real. If you have a high-quality chip (or an excellent bin like an ASRock Phantom), you can push lower. Here are the tiers of working settings reported by users:

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 If you want to skip the science and

Set to 2450 MHz and Min Frequency to 2350 MHz (keeping them within 100 MHz of each other helps with stability). VRAM & Power :

The AMD Radeon RX 6800 XT, built on the RDNA 2 architecture, remains a beloved GPU for its potent 1440p and entry-level 4K gaming performance. However, like many high-performance cards, its default "out-of-the-box" settings are engineered for stability above all else. This conservative approach results in excessive voltage being fed to the GPU core, leading to higher temperatures, increased fan noise, and reduced power headroom for performance boosting. The most effective solution to unlock the card's true potential is not overclocking, but rather a carefully tuned undervolt. For the RX 6800 XT, a stable undervolt in the range of (down from the stock ~1150-1200 mV) reliably works to deliver a cooler, quieter, and often faster gaming experience.

Since you are generating less heat, you can run fans slower for a quieter PC, or keep them high for max cooling. This link or copies made by others cannot be deleted

Change the Tuning Control from Automatic to Manual . Enable Controls: Enable GPU Tuning and Fan Tuning .

If your undervolt is active, TGP should drop to roughly .

. While stock voltage is usually 1150 mV, undervolting can significantly reduce temperatures and power draw—often by 40–50W—with minimal impact on performance. Recommended "Starting Point" Settings

For those looking for a quick starting point, these settings represent a "safe middle ground" that a vast majority of RX 6800 XT cards can achieve stably using AMD Software: Adrenalin Edition. Safe Conservative Profile (High Stability)
