Resetting System Setup (BIOS) Defaults Clears Overclocking Settings on the XPS 730x

When resetting the System Setup (BIOS) to its default settings on the XPS 730x and XPS 730x H2C, whether using the jumper or in BIOS keyboard commands, the factory shipped overclocked settings are reverted to a non-overclocked state. After defaults are loaded, the factory overclocked settings must be manually input.

Once the system has been overclocked, this does not mean that it will always run at the overclocked speed. The system will automatically throttle the speed when required, such as during performance taxing video games or applications. The only reliable place to determine the maximum speed once the system has been overclocked is in the system BIOS as many software applications may not reliably determine the maximum speed.
