An explanation of advanced BIOS setting (Aurora R3)

If your Bios has the Load Lvl 1/2/3 etc, those are 'factory' pre-set over-clocks, already dialed in; using those is a set-it & forget-it OC, no need for manual tuning from the other menus/sub-menus

Generally, memory is overclocked by enabling the XMP profile; or, manual settings in the overclocking menus you asked about

Due to four different Intel CPU sockets there are 4 Auroras: R1-R4. I don't know how the R3 Bios differs from let us say the R1, I don't know if the R3 got its own 'over-clocking' articles by AlienTech, but below is over-clocking information for Aurora R1 & A51 R1. The settings below are for a Gen1 i7, so they would never be appropriate for your R3, but as you can see, you can manually overclock the CPU & memory in the Bios. Most settings fine-tune the voltage & parameters; figuring out the right settings / parameters is what over-clocking is all about, since each CPU is unique, & needs dialed-in based on its own terms

You can do a forum search here in the top right search box, example 'overclocking Aurora R3' or insert your cpu model, see what u scare up. From there, I would use Bing/Google & do a similar search. Next, I might edit this post & change the title to: how do I overclock my Aurora R3, next I might make a companion post on AlienArena with the same title, OK?

CPU Overclocking

Overclocking on the Alienware Aurora R1 and Area 51 R1 - KB Article - 359781

Resetting System Setup (BIOS) Defaults Clears Overclocking Settings on Aurora & A51

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.

Overclock the Alienware Aurora or Area 51 to the Factory Overclocked Settings

1. 
   Reboot the computer.
2. 
   When prompted during POST, press the key to enter the setup screen.
3. 
   On the System Setup screen, use the and keys until Frequency/Voltage Control is highlighted, then press the key.
4. 
   On the Frequency/Voltage Control screen, press the key to highlight Load Level X OC setting (where X is the overclock level as received from the factory) and press the key ( Figure 1).
   

   	Note:
   	On the Alienware Aurora, only Load Level 1 OC setting is available. On the Alienware Area-51, Levels 1 through 3 are available.

5. 
   On the Load Level X OC setting? screen, press the key on [Ok].
6. 
   Press the key to return to the System Setup main screen.
7. 
   On the System Setup screen, use the key until Save Changes and Exit is highlighted, then press the key.
8. 
   On the Save configuration changes and exit setup? screen, press the key on Ok to restart the system.

Solution 2:

Overclocking the Area-51 and Aurora Manually

Alternatively, the below tables (Table 1, 2, 3 and 4) and instructions detail how to manually configure the factory overclocked settings on the Alienware Aurora or Area 51.

	Note:
	Alienware Aurora or Area 51 computers shipped with a processor other than the Intel Core i7 920 D0 and i7-975 XE are not factory overclocked.

1. 
   Reboot the computer.
2. 
   When prompted during POST, press the key to enter the setup screen.
3. 
   On the System Setupscreen, press the key to load setup defaults.
4. 
   On the Load Optimal Defaults? screen, press the key on Ok.
5. 
   On the System Setup screen, use the and keys until Frequency/ Voltage Control is highlighted, then press the key.
6. 
   On the Frequency/ Voltage Control screen, press the key to highlight Overclock Configuration and press the key.
7. 
   On the Overclock Configuration screen (Figure 2), press the key to highlight Intel (R) TurboMode Tech and press the key.
   
   Figure 2: The Overclock Configuration Screen with Factory Defaults for Overclock Level 1 Displayed
8. 
   On the Options menu, press the key to highlight Enabled and press the key.
9. 
   Press the key to highlight 1 Core CPU Turbo Ratio Limit and press the or keys to adjust Core Ratio to the value defined in Table 1, Table 2 or Table 3. Repeat this step for 2, 3, and 4 Core CPU Turbo Ratio Limit values.
   

   	Note:
   	For the Alienware Aurora, reference only Table 1. For the Alienware Area-51, whether Table 1, 2 or 3 are used, ensure the same table is used for all of the manual overclocking steps.

10. 
    Press the key to highlight Turbo Mode TDC Limit Override and use the number pad to adjust TDC to the value defined in Table 1, 2 or 3 and press the key once complete.
11. 
    Press the key to highlight Turbo Mode TDP Limit Override and use the number pad to adjust TDC to the value defined in Table 1, 2 or 3 and press the key once complete.
12. 
    Press the key to return to the Frequency/ Voltage Controlscreen.
13. 
    On the Frequency/ Voltage Control screen, press the key to highlight Overvoltage Configurationand press the key.
14. 
    Press the key on Dynamic CPU Vcore Offset ( Figure 3).
    
    Figure 3: The Overvoltage Configuration Screen with Factory Defaults for Overclock Level 1 Displayed
15. 
    On the Options screen, press the key to highlight the Dynamic CPU Vcore Offset value as defined in Table 1, 2 or 3and press the key to select the value.
16. 
    Press the key twice to return to the System Setup main screen.
17. 
    On the System Setup screen, use the key until Save Changes and Exit is highlighted, then press the key.
18. 
    On the Save configuration changes and exit setup? screen, press the key on Ok to restart the system.

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.

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.
