: Test in both demanding titles like Cyberpunk 2077 and high-FPS competitive games like Overwatch 2 , as cards can sometimes crash at high frame rates even if they pass stress tests. Troubleshooting
| Setting | Value | Rationale | | :--- | :--- | :--- | | | Enabled | Unlocks manual control. | | Min Frequency (Mhz) | 2300 | Prevents clock dropping too low. | | Max Frequency (Mhz) | 2450 | Sweet spot for thermal efficiency. | | Voltage (mV) | 1075 | The magic number. (Start here). | | VRAM Tuning | Enabled (Fast Timing) | Free performance. | | VRAM Max Frequency | 2110 Mhz | Stable for 90% of Samsung/ Micron dies. | | Power Limit (%) | +5% or +10% | Gives headroom for voltage dips. | | Fan Tuning | Enabled (Advanced) | 40% baseline, 70% at 80°C. |

Try lowering it by 10mV more until you find the minimum stable voltage. Crucial Note: Test Both Scenarios : Test in both demanding titles like Cyberpunk
Undervolting—the process of reducing the voltage supplied to the GPU while maintaining its clock speeds—is the most effective way to optimize this card. Here is a comprehensive look at how 6800 XT undervolt settings work, what results you can expect, and how to find the perfect balance for your rig. Why Undervolting the 6800 XT Works
Follow these steps within the AMD Adrenalin tuning menu to isolate your optimal stable voltage. 1. Enable Manual Tuning | | Max Frequency (Mhz) | 2450 |
Play demanding games (e.g., Cyberpunk 2077, Starfield) for at least 30 minutes.
Set this to 100 MHz below your Max Frequency (e.g., 2300 MHz) to keep clocks stable during gaming.
Sometimes, a GPU will pass heavy benchmarks but crash when transitioning out of a game back to the Windows desktop. Leave your system idling for 10 minutes after a gaming session to test this.
