This motherboard supports the latest Intel® Core™2 processors in LGA775 package. It also can support Intel® 45nm Multi-Core CPU. With new Intel® Core™ microarchitecture technology and 1600/1333/1066/800MH­z FSB, Intel® Core™2 processor is one of the most powerful and energy efficient CPU in the world.

Double Speed; Double Bandwidth
This motherboard supports the latest PCIe 2.0 devices for double speed and bandwidth which enhances system performance.

System Level Energy Saving
The new ASUS EPU - the world´s first power saving engine, has been upgraded to a new 4-engine version, which provides total system power savings by detecting current PC loadings and intelligently moderating power in real-time. The EPU automatically provides the most appropriate power usage for the CPU, VGA card, hard drives and CPU cooler fan - helping save power and money.

Active Quiet & Cool
ASUS Fan Xpert intelligently allows users to adjust the CPU fan speed according to different ambient temperature , which is caused by different climate conditions in different geographic regions and system loading. Built-in variety of useful profiles offer flexible controls of fan speed to achieve a quiet and cool environment.

0 to Internet in Seconds!
Express Gate™ is an ASUS exclusive OS that provides you with quick access to the Internet and key applications before entering Windows®.

This motherboard uses all high-quality Japan-made conductive polymer capacitors onboard for durability, improved lifespan, and enhanced thermal capacity.

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.

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.

Simply restore corrupted BIOS data from USB flash disk
The ASUS CrashFree BIOS 3 allows users to restore corrupted BIOS data from a USB flash disk containing the BIOS file. This utility saves users the cost and hassle of buying a replacement BIOS chip.

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.

This motherboard provides convenient connectivity to external home theater audio systems via coaxial S/PDIF-out (SONY-PHILIPS Digital Interface) jacks. It allows to transfer digital audio without converting to analog format and keeps the best signal quality.

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.

The motherboard and its packaging comply with the European Union´s Restriction on the use of Hazardous Substances (RoHS).
