6800xt Undervolt Settings Work

Power consumption typically drops by 30 to 50 watts.

Regardless of the model, the physics remain the same: Lower voltage equals lower temperature. Lower temperature equals higher sustained FPS.

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.

Finding the Sweet Spot: Do Your 6800 XT Undervolt Settings Actually Work?

Lower temps allow fan curves to run at lower RPMs. 6800xt undervolt settings work

Note: Every GPU has different "silicon lottery" results. These settings are a baseline. Some users report stability as low as 1020mV, while others require 1060mV–1070mV. 1. The "Safe & Cool" Baseline

Quick checklist

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)

This profile provides the best balance of power savings and stability for 90% of 6800 XT cards. 2400 MHz Voltage: 1050 mV (A 100mV drop from stock) VRAM Tuning: Fast Timing enabled, Max Frequency at 2100 MHz Power Limit: 0% or +5% 2. The Conservative Profile (Maximum Stability) Power consumption typically drops by 30 to 50 watts

: Use the built-in AMD Stress Test for 60 seconds to catch immediate crashes.

If your PC force-reboots or crashes, AMD Adrenalin will reset your performance tuning to factory defaults. This is a safety feature. To avoid losing your progress, use the button in the top right of the tuning menu to save your stable configurations to a file on your desktop. Game-Specific Instability

If your core temp is 65°C but your Hot Spot reads 95°C+ (a delta of over 30°C), your graphics card likely has poor thermal paste application or uneven mounting pressure. Undervolting helps mitigate this, but hardware maintenance may be required for a permanent fix. You applied 1075mV and your screen went black
