Question ASUS BIOS Default Settings vs Load Optimized Defaults?

[Redbird2012]

Can someone explain what the difference is between ASUS Default(F5) in EZ Mode vs Load Optimized Defaults in Advanced Mode (F7) under Exit tab? If you were going to do a BIOS update what would you choose to reset to factory settings for a clean BIOS update? Are they the same?

Default uses that, the default values embedded by the board manufacturer.
Optimized Defaults uses basic settings designed to get the most out of your installed hardware.

i would always use Optimized
unless troubleshooting odd behavior.
