64bit CPU support
64-bit computing, the next generation technology to replace current 32-bit architecture, delivers advanced system performance, faster memory access and increased productivity. This motherboard provides excellent compatibility and flexibility by supporting either 64-bit or 32-bit architecture.



DDR2 600 Native Support
Although Intel's 925X, 915P and 915G chipsets claimed to only support DDR2 400/533, ASUS engineers successfully unleashed their true potential. This model offers native DDR2 600, eliminating the bottleneck when overclocking both the CPU and memory. With current processors supporting 800MHz FSB, ASUS motherboards, the only solutions with native DDR2 600, will provide superior performance for the most demanding applications.

Hyper Path2 - Shorten Memory Latency
The innovative ASUS Hyper Path2 significantly shortens the latency time between the CPU and memory and improves memory performance without sacrificing stability.

AI Proactive

Stack Cool^&#153
Cooler Overclocking and Quieter Operation!
Heat causes instability and shortens system lifecycle, and motherboard power circuitry is a major thermal source. The patented Stack Cool?technology utilizes a mini PCB stacked against the main PCB to conduct heat away from power components, resulting in a 10^oCelsius reduction. And voila! Cooler overclocking, quieter fan operation, greater stability and longer system life without you doing a thing.

WiFi-g onboard (optional)
Wireless setup made affordable and easy!
WEP? SSID? Building a home WLAN used to be a hassle with confusing acronyms and cryptic menus. With WiFi-g^&#153and its one-touch setup wizard, high-speed wireless network is just a few clicks away. WiFi-g?serves as the access point of your network or if you already have an access point, it is also a wireless adapter for PCs to access existing WLAN.
(WiFi-g^&#153compliant to IEEE 802.11g 54 Mbps data transfer)

AI NOS
Boost performance when you need it the most!
Applications such as 3D games and video editing demand a huge chunk of system resource.
Inject "nitrous oxide" into your CPU! The patented AI NOS?(Non-delay Overclocking System) technology intelligently detects system load and automatically boosts performance for the most demanding tasks. Unlike other dynamic overclocking techniques, AI NOS?reacts much faster to satisfy your unending need for speeds.

AI NET2
Diagnose LAN connection before entering OS!
Network problems are often caused by bad cable connection.
AI NET2 remotely detects cable connection the second you turn on the system, and any faulty connections are reported back up to 100 meters at 1 meter accuracy.

High Definition Audio
Enjoy high-end sound system on your PC! The onboard 8-channel HD audio (High Definition Audio, previously codenamed Azalia) CODEC enables high-quality 192KHz/24-bit audio output, jack-sensing feature, retasking functions and multi-streaming technology that simultaneously sends different audio streams to different destinations. You can now talk to your partners on the headphone while playing a multi-channel network games. All of these are done on one computer. The Dolby Digital Live technology from Dolby Lab encodes the multi-channel audio source into AC-3 bit-stream and outputs it to S/PDIF port in real time.

Dual Gigabit LAN
The integrated dual Gigabit LAN design allows a PC to serve as a network gateway for managing traffic between two separate networks. This capability ensures rapid transfer of data from WAN to LAN without any added arbitration or latency. No more bottleneck to handle large amounts of data such as video, audio, and voice.

IEEE 1394b/a
1394b (FireWire 800) ?with its higher bandwidth up to 800 Mbps, longer distances and much higher-powered bus ?is more suitable for bandwidth-intensive applications like digital video (DV), professional audio, hard drives, which often consume hundreds or even thousands of megabytes of data per file. With backwards compatibility with 1394a, this motherboard provides 1 x 1394a and 2 x 1394b ports.

Serial ATA & IDE RAID
The onboard Silicon Image Sil3114R and ITE 8212F RAID controllers plus the Intel ICH6R southbridge provide the best solution to your RAID requirements on different storage standards. The Intel ICH6R supports RAID 0, 1 and Intel Matrix RAID Technology on 4 Serial ATA ports. The Silicon Image Sil3114R controller offers four additional SATA interfaces and allows RAID 0, 1, 10, JBOD, and a RAID software patch to support RAID 5. For IDE hard disk drives, the ITE 8212F controller provides RAID 0, 1 , 0+1 functionality for two ATA133 channels.

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

S/PDIF-out on Back I/O Port
This motherboard provides convenient connectivity to external home theater audio systems via an optical or coaxial S/PDIF-out (SONY-PHILIPS Digital Interface) jack. It allows to transfer digital audio without converting to analog format and keeps the best signal quality.

Max. 8 USB 2.0 ports supports
USB 2.0 is the latest connectivity standard for next generation components and peripherals. Backwards compatible with current USB 1.1 peripherals, USB 2.0 delivers transfer speeds up to 40 times faster at 480Mb/s, for easy connectivity and ultra-fast data transfers.

Multi-language BIOS
The multi-language BIOS allows you to select the language of your choice from the available options. The localized BIOS setup menu helps you configure your system easier and faster.

ASUS CrashFree BIOS2
The CrashFree BIOS2 feature now includes the BIOS auto-recovery function in a support CD. Users can reboot their system through the support CD when a bootable disk is not available, and go through the simple BIOS auto-recovery process.
ASUS motherboards now enable users to enjoy this protection feature without the need to pay for an optional ROM.

C.P.R.(CPU Parameter Recall)
When the system hangs due to overclocking failure, there is no need to open the case to clear CMOS data. Just simply restart the system, the BIOS would show the previous setting and then users can amend the CPU setting again.

WinDVD Suite (On Retail Version Only)
ASUS motherboards, intensifying leadership in the IT industry, now bundle the versatile InterVideo WinDVD Suite. This multifaceted software set includes the latest multimedia software(OEM version), bringing forth the multimedia features of ASUS motherboards to the best!
