such as LCD monitor. The interface of this motherboard supports dual VGA output
both DVI and RGB and is HDCP compliant allowing playback of HD DVD and
Blu-Ray Disc.. See page 1-24 for details.
DDR2 memory support
.
.......
The motherboard supports DDR2 memory which features data transfer rates of
800MHz/667MHz/533 MHz to meet the higher bandwidth requirements of the
latest 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 12.8 GB/s.
See page 1-13 for details.
PCI.Express™.interface..
The motherboard fully supports PCI Express, the latest I/O interconnect
technology that speeds up the PCI bus. PCI Express features point-to-point serial
interconnections between devices and allows higher clockspeeds by carrying data
in packets. This high speed interface is software compatible with existing PCI
specifications. See page 1-20 for details.
Serial ATA 3.0Gb/s technology
......

Chapter 1: Product introduction
ASUS O.C. Profile
..
The motherboard features the ASUS O.C. Profile that allows users to conveniently
store or load multiple BIOS settings. The BIOS settings can be stored in the
CMOS or a separate file, giving users freedom to share distribute their favorite
overclocking settings. See pages 2-37 for details.
ASUS.MyLogo2™.
This feature allows you to personalize and add style to your system with
customizable boot logos. See page 2-33 for details.
ASUS.CrashFree.BIOS.3.
..
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. See page 2-10 for details.
ASUS.EZ.Flash.2.
EZ Flash 2 is a user-friendly BIOS update utility. Simply press the predefined
hotkey to launch the utility and update the BIOS without entering the OS. Update
your BIOS easily without preparing a bootable diskette or using an OS-based flash
utility. See pages 2-6 and 2-39 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. See page
1-21 for details.

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, ensure that 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 that 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.
