8 Phase Power Design
The ASUS 8-Phase Power Design provides highly efficient operation to generate less heat (at least 15°C (59°F)) than other conventional power solutions. It reduces input ripple current and output ripple voltage, which keeps CPU and power module from suffering the risk of high power stress. It has the advantages of quick transient response and stability, especially beneficial when CPU requires more current immediately under heavy loading or overclocking mode.

Fanless Design - Stack Cool 2: Effective and zero-noise heat dissipation
Stack Cool 2 is a fan-less and zero-noise cooling solution offered exclusively by ASUS. It effectively transfers heat generated by the critical components to the other side of the specially designed PCB (printed circuit board) for effective heat dissipation.

Fanless Design - Heat Pipe: Support side-flow fan or passive cooler
The Heat Pipe design effectively directs the heat generated by the chipsets to the heatsink near the back IO ports, where it can be carried away by existing airflow from CPU fan or bundled optional fan. The purpose of the innovative heat pipe design on this motherboard is that the groundbreaking fanless design does not have lifetime problems as a chipset fan does. Furthermore, it provides options for users to install side-flow fan or passive cooler. The Heat Pipe design is the most reliable fanless thermal solution to date.

Optional Fan (for Water-Cooling or Passive-Cooling only)
Maximize Water-Cooling or Passive-Cooling performance!
The optional fan is specifically designed to provide sufficient airflow over the CPU power modules and chipset area when water-cooling or passive-cooling is utilized, ensuring effective heat dissipation for the entire system.

Q-Fan 2: Adjusts both CPU fan and chassis fan speeds according to system loading
ASUS Q-Fan2 technology intelligently adjusts both CPU fan and chassis fan speeds according to system loading to ensure quiet, cool and efficient operation.

Q-Connector: Make connection quick and accurate!
The ASUS Q-Connector allows you to connect or disconnect chassis front panel cables in one easy step with one complete module. This unique adapter eliminates the trouble of plugging in one cable at a time, making connection quick and accurate. .

EZ Flash 2: Simply update BIOS from a USB flash disk before entering the OS
EZ Flash 2 is a user-friendly BIOS update utility. Simply launch this tool and update BIOS from a USB flash disk before entering the OS. You can update your BIOS only in a few clicks without preparing an additional floppy diskette or using an OS-based flash utility.

Precision Tweaker: Achieve system maximum performance!
It offers ways to raise system performance inch-by-inch and step-by-step to achieve maximum performance! This is about getting the most out of your machine and taking pride in your customized computer.
vDIMM - Take control of how much power is going into the memory modules. This motherboard gives you 13-step voltage control to the DIMM.
vCore - Find out "exactly" how much power your CPU needs. Fine-tune it with 0.0125 volts at a time!
SFS (Stepless Frequency Selection) allows
- FSB tuning from 100MHz up to 650MHz at 1MHz increment
- Memory tuning from 533MHz up to 1066MHz at 1MHz increment
- PCI Express frequency tuning from 100MHz up to 150MHz at 1MHz increment

Noise Filter: Eliminate background noise while recording
This feature detects repetitive and stationary noises like computer fans, air conditioners, and other background noises then eliminates it in the incoming audio stream while recording.

Array Mic: Eliminate interferences in the reception cone
Enhance speech-centric applications
The bundled Superbeam Array Microphone receives only the sound coming from the reception cone and ignores the sound coming from other directions. This mechanism eliminates a large number of interferences including neighboring speakers and reverberations. It also uses advanced de-reverberation techniques to reduce echo and minimize its effect on the speech engine. This feature can enhance speech-centric application like Skype, online game, video conference and recording.

MyLogo2: Personalize your system with customizable boot logo
You can convert your favorite photo into a 256-color boot logo for a more colorful and vivid image on your screen.
