6800xt Undervolt Settings Work Jun 2026

: Run your benchmark again. If it finishes without crashing or visual glitches, drop another 25 mV .

For most users, these settings provide a stable starting point that balances power savings with performance: 1050 mV to 1100 mV (Stock is typically 1150 mV). Max Frequency: 2400 MHz – 2500 MHz. 6800xt undervolt settings work

Set to 2100–2150 MHz with "Fast Timings" enabled for a small performance boost. : Run your benchmark again

You applied 1075mV and your screen went black. Does this mean undervolting doesn't work? No. It means your specific chip needs a tiny bit more juice. Max Frequency: 2400 MHz – 2500 MHz

Why does performance go up with less voltage? Lower voltage reduces thermal throttling and allows the boost algorithm to sustain higher clocks for longer.

These users are lying or only ran Furmark for 30 seconds. True stability requires testing three distinct workloads:
