6800xt Undervolt Settings Work !!top!! -

This guide covers how to safely undervolt your AMD Radeon RX 6800 XT to lower temperatures, reduce fan noise, and often improve performance (by allowing higher sustained boost clocks).

Profile A – Silent / Efficiency Focus

  • Voltage: 1025 mV
  • Max Freq: 2250 MHz (or stock)
  • VRAM: Fast Timing, 2100 MHz
  • Power draw: ~180–200W (stock: 250–270W)
  • Performance: 95% of stock
  • Temp drop: ~12°C

Step 3: Memory Tuning (Fast VRAM)

The 6800 XT has fast memory that can easily be overclocked. Undervolting the core saves power, which creates thermal headroom for the memory. 6800xt undervolt settings work

  1. Under VRAM Tuning, select Custom.
  2. Increase the Max Frequency.
    • Stock: 2000 MHz (effective 16 Gbps).
    • Safe Start: 2100 MHz (Fast Timing enabled).
    • Aggressive: 2150 MHz - 2200 MHz.
  3. Tip: If you enable "Fast Timing," you may need to lower the frequency slightly compared to standard timing.

Step-by-Step: How to Apply Your Undervolt

  1. Open AMD Software: Adrenalin Edition.
  2. Click Performance (top tab) > Tuning (sub-tab).
  3. Click Custom (under GPU Tuning).
  4. Enable GPU Tuning.
    • Enable Advanced Control.
    • Set Min Frequency (Mhz) to 2300.
    • Set Max Frequency (Mhz) to 2450.
    • Set Voltage (mV) to 1075.
  5. Enable VRAM Tuning.
    • Enable Advanced Control.
    • Set Max Frequency (Mhz) to 2110.
    • Click Enable Fast Timing.
  6. Enable Power Tuning.
    • Set Power Limit (%) to +10.
  7. Enable Fan Tuning.
    • Enable Advanced Control.
    • Set a "Tuning" curve (e.g., 30% at 30°C, 60% at 80°C).
  8. Click Apply Changes (Top right corner).

Overview

This examination analyzes undervolting an AMD Radeon RX 6800 XT to reduce power draw and temperatures while preserving—often improving—stable performance. It covers methodology, testing protocol, specific voltage/frequency targets, expected outcomes, monitoring, and troubleshooting. Follow carefully; results vary by silicon lottery, cooling, and PSU.

The "Universal" Starting Point: Settings That Work for 90% of Chips

If you want to skip the science and just get into a game, use this baseline profile. It is aggressive enough to matter, but conservative enough to avoid crashing in most DirectX 12 titles.

Software needed: AMD Software: Adrenalin Edition (no third-party tools required).
