How can I restore your BIOS tuning after a BIOS update? Depends on the motherboard and the update, BIOS updates may reset certain or all BIOS settings. Also, it is generally recommended to perform a BIOS reset after BIOS updates – this reset will definitely set settings back to the mainboard vendor's factory defaults. So you will need to check certain settings before and after:RAM: Selecting the XMP or EXPO profile.Reloading or selecting any customised fan profiles.Checking other performance-related settings.For motherboards whose BIOS setup offers a corresponding import/export function (this applies to almost all motherboards; the only exceptions at present are AMD Threadripper models), the settings are also saved as a BIOS profile file on a USB stick provided with the motherboard.Alternatively, you can also take a photo of the relevant menus yourself before a BIOS update or a BIOS reset, or export a current profile.
