Resetting System Setup (BIOS) Defaults Clears Overclocking Settings on the Alienware Aurora and Area 51

When resetting the System Setup (BIOS) to its default settings on the Alienware Aurora and Area 51, 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.

Intel Extreme Tuning Utility
Dell recommends only using the AutoTune feature and that you choose the 1st option, "Stay within the manufacturer's limits". If you decide to use the Manual Tune feature, users should be knowledgeable about advanced PC hardware settings. Improper settings can permanently damage the PC.

Use the Intel Turbo Mode tech with the Balanced Power setting. Let it clock down. There is no reason to run it at 3.6,3.7,3.8 or whatever all the time. You can go for the 4.0 or 4.1 just don't make it run like that all the time.

* Adjusting the CPU BClk to values higher than 160MHz

In case of PC failures due to Overclocking
The Bios will try to recover itself by setting the system to factory defaults, after a third post failure. In case the Bios cannot be recovered, then the CMOS has to be manually reset by moving the CMOS jumper and removing the Coin Cell battery. Once the system is able to complete the post, access the Bios and reset Load Level 1 Settings to load the factory 3.20GHz configuration. When resetting the System Setup (BIOS) to its default settings on the Alienware Aurora and Area 51, 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.
