6800xt Undervolt Settings Work ((better)) Jun 2026

Finding the perfect undervolt settings for your AMD Radeon RX 6800 XT transforms the GPU. This process reduces power consumption, lowers temperatures, and keeps your PC quiet. It achieves all this without sacrificing your in-game frame rates.

Learning how to undervolt your RX 6800 XT is a skill that pays off immediately. By finding the right 6800XT undervolt settings for your specific card, you unlock a cooler, quieter, and more efficient GPU. The "working settings" aren't a single number, but a range you discover through a simple process of trial and error using a tool like AMD Adrenalin. Your card will thank you for it with lower temperatures and often higher, more stable performance.

What of 6800 XT do you have? (e.g., Reference, ASUS TUF, PowerColor Red Devil) What power supply wattage are you currently using? 6800xt undervolt settings work

: Run 3DMark Time Spy or Heaven Benchmark . If your score increases or stays the same while temperatures drop, the undervolt is working.

As you can see, the undervolted settings result in similar performance, but with significantly reduced power consumption and temperatures.

Avoid running MSI Afterburner simultaneously with AMD Adrenalin software for voltage control. They will fight for hardware hooks and cause resets. Use one or the other. [Open AMD Adrenalin] -> [Performance Tab] -> [Tuning]

Cooler silicon means the GPU fans do not need to spin at maximum RPM, resulting in a dramatically quieter gaming rig.

Since you are generating less heat, you can run fans slower for a quieter PC, or keep them high for max cooling.

| Symptom | Likely Cause | Fix | |---------|--------------|-----| | Driver timeout (black screen) | Voltage too low | Increase by 10–15 mV | | Artifacts / flickering | Unstable core or VRAM | Reduce VRAM clock or raise voltage | | Lower than expected performance | Clock stretching (throttling) | Raise voltage slightly (e.g., 1025 → 1040 mV) | | Crash only in Ray Tracing | Higher voltage needed for RT workloads | Use separate profile or add +20 mV | Learning how to undervolt your RX 6800 XT

These values represent common stable starting points for the RX 6800 XT AMD Software: Adrenalin Edition

This profile targets maximum power savings with zero performance loss. 2350–2400 MHz Voltage: 1025–1050 mV

Open AMD Adrenalin, go to Performance > Tuning , switch Tuning Control to Custom , and enable GPU Tuning and Advanced Control .

: Decreases fan speeds due to lower thermal output.

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
