Setting this to 2400–2450 MHz is a common stable range for a daily undervolt.
Here’s a reliable process to find your card's perfect settings using the most common approach.
If you have a well-binned card, this profile maximizes power savings and runs incredibly cool. 2400 MHz Voltage (mV): 1025 mV – 1050 mV Memory Tuning: Fast Timing, 2120 MHz Power Limit: +15% Step-by-Step Guide to Undervolting the 6800 XT
As one user noted, you must test in both high-demand, low-FPS games (e.g., Cyberpunk ), and low-demand, high-FPS competitive games (e.g., Overwatch 2 or Valorant ). Sometimes an undervolt that works in a heavy game will crash in a light game, as the card acts differently at high frame rates. Conclusion 6800xt undervolt settings work
Based on user results and expert testing, these are common targets for an undervolt:
This profile focuses on maximum stability while still yielding great thermal drops. 2350 MHz Voltage (mV): 1075 mV – 1100 mV Memory Tuning: Fast Timing, 2100 MHz
) for 15–30 minutes. If it crashes, increase the voltage by 10 mV and try again. Why Undervolt? Setting this to 2400–2450 MHz is a common
1025mV - 1050mV (Start at 1050mV and work down). Max Frequency: 2400MHz - 2500MHz
Fast Timing enabled, Max Frequency at 2100 MHz
GPU edge temperatures generally drop by 5°C, while the critical Hotspot/Junction temperature can plummet by 10°C to 15°C. 2400 MHz Voltage (mV): 1025 mV – 1050
If you have a decent chip, aim for higher clocks with lower voltage. Max Frequency: VRAM Clock: (Fast Timing Enabled). Power Limit: How to Apply Settings (AMD Adrenalin Software)
Stability testing is the most critical step.
You need a reliable way to test stability and log your baseline metrics. Download or Superposition , alongside HWMonitor or HWInfo64 to track temperatures. Step 2: Establish a Baseline
remains a formidable GPU in 2026, often nicknamed part of AMD's "Fine Wine" lineup. However, out of the box, it often runs hot and pulls excessive power to maintain high clock speeds. —the process of reducing the voltage supplied to the GPU while maintaining the same or higher performance—is the best way to optimize this card.
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 ?
