Work | 6800xt Undervolt Settings

Undervolting creates a unique stability curve. A card might be stable in Cyberpunk 2077 for an hour but crash instantly in Furmark or Superposition.

If you crash:

You cannot ignore memory tuning when asking if undervolt settings work. The Infinity Cache on the 6800XT loves low latency.

Warning: Overclocking VRAM adds heat to the memory controller. If you undervolt too aggressively (sub 1050mV) AND use Fast Timings at 2150Mhz, you will get "memory correction errors" (lower FPS despite higher clock). 6800xt undervolt settings work

can significantly reduce power consumption by up to 30% and drop junction temperatures by 20–30°C with negligible performance loss. While every card is unique due to the "silicon lottery," most stable undervolts for this card fall between 1025 mV and 1075 mV.

Undervolting the AMD Radeon RX 6800 XT can significantly reduce power consumption by up to 80W and drop temperatures by 10–15°C with minimal performance loss. Recommended Undervolt Settings

Because of the "silicon lottery," every card performs differently. Below are three tiers of settings users commonly find stable: If you crash: You cannot ignore memory tuning

| Setting | Value | Rationale | | :--- | :--- | :--- | | GPU Tuning | 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. |

Does this specific setting work? For a standard Sapphire Pulse or Gigabyte Gaming OC, yes. Run Time Spy or play Cyberpunk 2077 for 20 minutes. If you don’t crash, you are done.
