The first tab, which also happens to be the most interesting one, is named Extreme Tweaker. If you're looking to extract more performance out of your computer, this is where you'll want to hang out. The first third of the page is all about clock speeds, whether it is the processor's multiplier, base clock, memory divider, uncore or QPI clock, it's all there. Up top are the target processor and memory clocks, no more need to keep a calculator at hand. The BIOS does the math for you and clearly displays it.

The first few options are geared toward beginners and offer some extremely simple, yet effective, overclocking possibilities. For example, Asus includes some presets so you can simply choose to upgrade to a 940 or even a 965 and the BIOS will do all the required adjustments. The board also supports Intel's XMP, eXtreme Memory Profiles.

The second part offers more advanced options including settings regarding the EPU, Energy Processing Unit. It can be set to automatically monitor and adjust voltages as the load changes or you can simply set it off and use the full blown power distribution system. Lower down the list, Extreme OV, for OverVoltage, allows voltage settings to be set much higher than you normally could. For example, the processor's core voltage can be set up to 2.5V, which is obviously not recommended for anything other the extreme cooling.

The last third of the page is where the rest of the voltage tweaking is done. The list isn't overwhelming and is complete enough to satisfy everyone. If Extreme OV was previously enabled, voltages can be set incredibly high and will please even the most extreme overclockers. At the bottom are some more advanced tweaking options including spread spectrum, which should be disabled if you're seeking high clocks, and clock skew adjustments.

The DRAM Timing Control page has a whole bunch of timings that can be manually set. The most important ones are the first four as well as the DRAM Timing Mode.

The second half of the page has some even more obscure subtimings.

DRAM REF Voltages is another page for advanced memory tweaking. Those settings are mostly for people wanting to get every last Hertz out of their memory.

Moving to the boring stuff, the Main tab is where the date, time and language can be set. It also displays the installed components on the SATA ports, whether they are hard or optical drives.

In the Storage Configuration page, one can set the drives in IDE, AHCI or RAID mode.
