If your card has average silicon quality, use this profile to guarantee stability while still cutting heat. 2350 MHz Voltage: 1075 mV VRAM Tuning: Default Timing, Max Frequency at 2000 MHz Power Limit: 0% 3. The Aggressive Profile (High Silicon Quality)
If you are looking to lower your temps, reduce fan noise, and even gain a few extra frames, understanding is crucial. This guide will take you through the principles, safe settings, and the methodology to make it stable. What Does Undervolting a 6800 XT Actually Do?
Here is the paradox:
If the driver detects even a microsecond of instability, it resets to factory defaults as a safety measure. If this happens, raise your voltage by +10mV and test again.
A setting might work on your desktop but crash during a heavy gaming session. You must stress test your changes. 6800xt undervolt settings work
Performance stays within 1% to 2% of stock values, or slightly improves due to consistent clock speeds. If you want to fine-tune your card further, let me know:
Increasing the power limit to +15% is recommended to ensure the card isn't artificially throttled while you are testing for voltage stability.
Expected outcomes
Start here. These settings mimic the average silicon capabilities of the Navi 21 XT chip and work for almost every card. 2300 MHz Max Frequency (MHz): 2450 MHz Voltage (mV): 1075 mV (Stock is 1150 mV) Power Limit (%): +15% If your card has average silicon quality, use
Operating at lower voltages and temperatures can theoretically extend the hardware's lifespan. Recommended "Sweet Spot" Settings How to UNDERVOLT AMD RX 6000 Series GPUs
: Run 3DMark Time Spy or Heaven Benchmark . If your score increases or stays the same while temperatures drop, the undervolt is working.
| 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 |
Synthetics load the GPU uniformly, but games feature variable loads that stress the voltage regulators during sudden transitions (e.g., opening a menu or loading a new zone). This guide will take you through the principles,
You can perform these steps directly within the under the Performance > Tuning tab. How to UNDERVOLT AMD RX 6000 Series GPUs
However, there is an open secret among PC enthusiasts: the 6800XT runs hot, loud, and power-hungry out of the box. The solution isn't liquid nitrogen or a $400 water block. It’s a simple, free tweak called undervolting. But if you’ve spent any time on forums like r/AMD or Overclock.net, you’ve seen the frantic question repeated hundreds of times: “Do 6800XT undervolt settings actually work?”
Test the safe profile in demanding titles that utilize heavy ray tracing or high GPU compute loads, such as Cyberpunk 2077 , Metro Exodus , or Alan Wake 2 . Play for at least two hours to confirm long-term stability. Troubleshooting Common Issues Settings Reset After Reboot
