What is a Dual Bios?
Dual Bios feature was about overclocking. How so? Users would leave Bios1 default as a fallback while they would flash a custom Bios on Bios2 for overclocking purposes.
But the Dual Bios functionality has changed over the years. The Dual Bios function now is more about performance
Example
ZOTAC GAMING GPUs feature two profiles: AMPLIFY and QUIET[1]
- AMPLIFY, the default bios out of the box, enables a more aggressive fan profile allowing the fans to spin faster to maintain the GPU at cooler temperatures. When the GPU is running cooler, it has the potential to perform faster with more headroom for the boost clock to boost further and for more sustained periods. The negating benefit to cooler temperatures is an increase in noise because the fans are spinning faster.
- QUIET, does exactly what it says. It will enable quieter performance by reducing the speeds the fans spin at, while also allowing warmer GPU temperatures. You can still expect great GPU performance but at quieter noise levels.
