• LGA775 Intel Core 2 Processor Ready
  This motherboard supports the latest Intel Core 2 processors in LGA775 package. With new Intel Core microarchitecture technology and 1066/800 MHz FSB, Intel® Core 2 processor is one of the most powerful and energy efficient CPU in the world.
• Intel P965 Chipset
  The Intel P965 Express Chipset is the latest chipset designed to support maximum 8GB dual-channel DDR2 800/667/533 architecture, 1066/800 FSB (front-side-bus), PCI Express x16 graphics and multi-core CPU. It especially includes Intel Fast Memory Access Technology that significantly optimizes the use of available memory bandwidth and reduces the latency of the memory accesses.
• ATI CrossFire Technology
  ATI’s CrossFire boosts image quality along with rendering speed, eliminating the need to crank down screen resolutions to get the high image quality you want. CrossFire ignites with the higher antialiasing, anisotropic filtering, shading, and texture settings you desire. Adjust your display configurations, experiment with your advanced 3D settings, and check the effect with a real-time 3D-rendered preview within ATI’s Catalyst™ Control Center to rule your CrossFire system.
• Asus C.G.I. (Cross Graphics Impeller)
  CrossFire performance optimization offered by C.G.I occurs in Direct Media Interface (DMI) between the P965 Northbridge, which carries one x16 PCI Express slot (x16 PCI Express Lanes), and ICH8R Southbridge, where another x16 PCI Express slot (x4 PCI Express Lanes) resides. C.G.I streamlines data transfer between the Northbridge and Southbridge, delivering enhanced performance during Crossfire dual-GPU mode.

• AI Gear. Optimize performance and quietness as you wish!
  To balance both system performance and quietness, AI Gear allows users to choose from profiles to adjust CPU frequency and vCore voltage, minimizing system noise and power consumption. Users can real-time change the mode under operating system to suit their needs.
• AI Nap. Minimize noise and power consumption when temporarily away!
  With AI Nap, users can instantly snooze your PC without terminating the tasks. System will continue operating at minimum power and noise when user is temporarily away. It keeps downloading files or running applications in quietest state while you’re sleeping. Simply click keyboard or mouse, you can swiftly wake up the system in few seconds.
• 8 Phase Power Design. Cooler and quieter system. Longer components lifespan. More stable and reliable under heavy-loading and overclocking.
  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. Zero failure. Supports 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.

• 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.
• DTS Connect. This feature is consists of two elements: DTS interactive and DTS NEO:PC. DTS interactive re-encodes your stereo or multi-channel sound into a DTS audio signal and send it out from your PC to any DTS enabled system. While DTS NEO:PC turns your stereo audio such as MP3, WMA, CD, and other sound format into a convincing multi-channel audio experience.
