1.3 Special features
1.3.1 Product highlights
Intel® Core™2 Extreme / Core™ 2 Quad /
Core™2 Duo Processor Support
This motherboard supports the latest Intel® Core™ 2 Extreme / Core™ 2 Quad /
Core™ 2 Duo processors in the LGA775 package. It is excellent for multi-tasking,
multi-media and enthusiastic gamers with 1600 / 1333 / 1066 / 800 MHz FSB. The
Intel® Core™ 2 series processor is one of the most powerful CPUs in the world. This
motherboard also supports Intel® CPUs in the new 45nm manufacturing process.
See page 2-5 for details.
Intel® P45 Chipset
The Intel® P45 Chipset is the latest chipset designed to support dual-channel
DDR2 800/667 MHz memory architecture, 1333/1066/800 MHz FSB (Front Side
Bus), PCIe 2.0, and multi-core CPUs. It especially includes Intel
Access technology that signicantly optimizes the use of available memory
bandwidth and reduces the latency of the memory accesses.
PCIe 2.0
This motherboard supports the latest PCIe 2.0 device for twice the current speed
and bandwidth. This enhances system performance while still providing backward
compatibility to PCIe 1.0 devices. See page 2-19 for details.
®
Fast Memory
Dual-Channel DDR2 1200 memory support
The motherboard supports DDR2 memory that features data transfer rates of
1200 / 1066 / 800 / 667 MHz to meet the higher bandwidth requirements of the
latest operating system, 3D graphics, multimedia, and Internet applications. The
dual-channel DDR2 architecture doubles the bandwidth of your system memory to
boost system performance, eliminating bottlenecks with peak bandwidths of up to
19.2 GB/s. See page 2-11 for details.
Serial ATA 3.0 Gb/s technology
This motherboard supports the next-generation hard drives based on the Serial
ATA (SATA) 3Gb/s storage specication, delivering enhanced scalability and
doubling the bus bandwidth for high-speed data retrieval and saves. See page 2-27
for details.
1-2 Chapter 1: Product Introduction
IEEE 1394a support
The IEEE 1394a interface provides high speed digital interface for audio/video
appliances such as digital television, digital video camcorders, storage peripherals
& other PC portable devices. See page 2-30 for details.
S/PDIF digital sound ready
This motherboard provides convenient connectivity to external home theater audio
systems via coaxial and optical 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. See page 2-32 for details.
High Denition Audio
Enjoy high-end sound quality on your PC! The onboard 8-channel HD audio (High
Denition Audio, previously codenamed Azalia) CODEC enables high-quality
192KHz/24-bit audio output that simultaneously sends different audio streams to
different destinations. You can now talk to your partners on the headphone while
playing multi-channel network games. See pages 2-23 and 2-24 for details.
100% Japan-made conductive polymer capacitors
This motherboard uses all high-quality conductive polymer capacitors for durability,
improved lifespan and enhanced thermal capacity.
Green ASUS
This motherboard and its packaging comply with the European Union’s Restriction
on the use of Hazardous Substances (RoHS). This is in line with the ASUS vision
of creating environment-friendly and recyclable products/packagings to safeguard
consumers’ health while minimizing the impact on the environment.
1.3.2 ASUS special features
ASUS Express Gate
Taking only 5 seconds to go online from bootup, Express Gate is the one-stop

1.3.3 ASUS Exclusive Overclocking Features
AI Booster
The ASUS AI Booster allows you to overclock the CPU speed in Windows
environment without the hassle of booting the BIOS. See page 4-23 for details.
Precision Tweaker 2
Allows the user to adjust the NB Voltage, FSB termination Voltage, CPU PLL
Voltage and the DRAM Voltage in 0.02v steps to netune voltages to achieve the
most precise setting for the ultimate customized overclocking conguration. See
pages 3-21–3-22 for details.
C.P.R. (CPU Parameter Recall)
The C.P.R. feature of the motherboard BIOS allows automatic re-setting to the
BIOS default settings in case the system hangs due to overclocking. When the
system hangs due to overclocking, C.P.R. eliminates the need to open the system
chassis and clear the RTC data. Simply shut down and reboot the system, and the
BIOS automatically restores the CPU default setting for each parameter.

2.1 Before you proceed
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
• Unplug the power cord from the wall socket before touching any
component.
• Use a grounded wrist strap or touch a safely grounded object or a metal
object, such as the power supply case, before handling components to
avoid damaging them due to static electricity.
• Hold components by the edges to avoid touching the ICs on them.
• Whenever you uninstall any component, place it on a grounded antistatic
pad or in the bag that came with the component.
• Before you install or remove any component, ensurethat the ATX power
supply is switched off or the power cord is detached from the power
supply. Failure to do so may cause severe damage to the motherboard,
peripherals, and/or components.
Onboard LED
The motherboard comes with a standby power LED. The green LED lights up
to indicate that the system is ON, in sleep mode, or in soft-off mode. This is a
reminder that you should shut down the system and unplug the power cable before
removing or plugging in any motherboard component. The illustration below shows
the location of the onboard LED.
