6800xt Undervolt Settings Work |top|

Start by setting the to 1075 mV (stock is usually 1150 mV).

You get similar or better performance for less wattage. Step-by-Step: How to Undervolt in AMD Adrenalin

The best tool for this is the official AMD Adrenalin software. Open Adrenalin, go to the tab, then Tuning . Set Tuning Control to Manual .

) for 15–30 minutes. If it crashes, increase the voltage by 10 mV and try again. Why Undervolt? 6800xt undervolt settings work

If you’d like, give your card’s baseline numbers and I’ll produce a step-by-step, numbered undervolt profile to try.

Don't neglect the VRAM in Adrenalin. Enabling provides a nice memory bandwidth boost. Aim for frequencies between 2100 MHz and 2150 MHz. Going higher (2150 MHz+) can introduce memory errors or crashes, even if the core undervolt is stable.

| Parameter | Default Settings | After Undervolt | Improvement | | :--- | :--- | :--- | :--- | | | 2400 MHz | 2500 MHz | +100 MHz | | Voltage | 1150 mV | 975 mV | -175 mV | | GPU Temperature | 70°C | 55°C | -15°C | | Junction Temp | 85°C | 70°C | -15°C | | Power Consumption | ~300W | ~200W | -100W | | Fan Speed | 2400+ RPM | ~1700 RPM | Quieter | Start by setting the to 1075 mV (stock is usually 1150 mV)

Every individual GPU behaves differently due to manufacturing variances. However, the RX 6800 XT community has established reliable baseline settings that serve as an excellent starting point for most cards. Stock vs. Target Settings 1150 mV Safe Target Undervolt: 1025 mV to 1075 mV Aggressive Target Undervolt: 1000 mV to 1025 mV Recommended Starting Profile

: Test in both demanding titles like Cyberpunk 2077 and high-FPS competitive games like Overwatch 2 , as cards can sometimes crash at high frame rates even if they pass stress tests. Troubleshooting

This method manually lowers the voltage limit while keeping high frequencies. This is how you get better performance and lower temps. Open Adrenalin, go to the tab, then Tuning

Passing a quick 10-minute benchmark does not mean your settings are stable. True stability requires testing across different graphics APIs, loads, and engines.

Because of the "silicon lottery," every card responds differently. However, these are the most common stable starting points: Profile Type Max Frequency VRAM / Timings 2350 - 2400 MHz 1050 - 1075 mV Stock / Default Balanced (Sweet Spot) 2400 - 2500 MHz 1020 - 1035 mV 2100 MHz / Fast Timings Extreme (High Performance) 980 - 1010 mV 2150 MHz / Fast Timings

What is your (e.g., XFX Merc, Sapphire Nitro, Reference)? What is your power supply (PSU) wattage ? Are you experiencing crashes or just high noise ?
