For a balanced profile that yields immediate results without sacrificing stability, try these parameters in AMD Software: Adrenalin Edition: 2300 – 2400 MHz Voltage (mV): 1050 mV
Run UNIGINE Superposition on the "1080p Extreme" or "4K Optimized" preset.
Set the Power Limit to maximum (+15%) to allow the card flexibility for stability. 6800xt undervolt settings work
| Metric | Stock Defaults (1150 mV) | Working Undervolt (970 mV) | | :--- | :--- | :--- | | | 1150 mV | 970 mV (-180 mV) | | GPU Clock Speed | ~2260 MHz (throttled) | ~2395 MHz (sustained) | | Power Consumption | 255 Watts | 210 Watts | | GPU Temperature | 80°C | 73°C | | Junction Temp | 106°C (Hot) | 85°C (Safe) | | Fan Speed | ~1730 RPM (Loud) | Quieter |
Because AMD’s boost algorithm (Precision Boost Overdrive/RDNA2 telemetry) is highly sensitive to thermal headroom, lowering the temperature often allows the card to sustain its maximum boost clocks for longer periods. The Real-World Benefits For a balanced profile that yields immediate results
Here’s a reliable process to find your card's perfect settings using the most common approach.
Based on user results and expert testing, these are common targets for an undervolt: The Real-World Benefits Here’s a reliable process to
. Stable settings depend on the specific GPU (the "silicon lottery"), but many cards operate efficiently between 1025 mV and 1075 mV Recommended Target Settings
Before discussing settings, you must understand the enemy: the stock voltage curve. AMD, like NVIDIA, ships its cards with a conservative voltage buffer. For the Navi 21 chip (the heart of the 6800XT), the stock voltage typically sits between .
Many users report stability around 1025 mV to 1050 mV while holding a solid 2400-2500 MHz core clock.
