Special features

1.3.1

Product highlights

The motherboard comes with a 939-pin surface mount, Zero Insertion

Force (ZIF) socket that supports AMD Athlon™ 64/Athlon™ 64FX/Athlon™

64 X2/AMD Sempron™ 64 processors. With an integrated low-latency high-bandwidth memory controller and a highly-scalable HyperTransport™ technology-based system bus, the motherboard provides a powerful platform for your diverse computing needs, increased office productivity, and enhanced digital media experience. See page 1-8.

Employing the Double Data Rate (DDR) memory technology, the motherboard supports up to 2 GB of system memory using DDR400/333

DIMMs. The ultra-fast 400MHz memory bus delivers the required bandwidth for the latest 3D graphics, multimedia, and Internet applications. See page

1-10 for details.

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 1-17 for details.

The AGP 8X (AGP 3.0) VGA interface specification enables enhanced graphics performance with high bandwidth speeds up to 2.12 GB/s. See page 1-18 for details.

The motherboard supports the Serial ATA technology through the Serial ATA interfaces and the VIA VT8251 Southbridge. The Serial ATA II specification provides twice the bandwidth of the current Serial ATA products with a host of new features, including Native Command Queueing (NCQ), Power

Management (PM) Implementation Algorithm, and Hot Swap. Serial ATA allows for thinner, more flexible cables with lower pin count, reduced voltage requirement, and data transfer rates of up to 150 MB/s for SATA I and 300

MB/s for SATA II. See page 1-26 for details.

The motherboard supports the S/PDIF Out function through the S/PDIF interfaces on the rear panel and at midboard. The S/PDIF technology turns your computer into a high-end entertainment system with digital connectivity to powerful audio and speaker systems. See page 1-27 for details.

The motherboard implements the Universal Serial Bus (USB) 2.0

specification, dramatically increasing the connection speed from the

12 Mbps bandwidth on USB 1.1 to a fast 480 Mbps on USB 2.0. USB 2.0 is backward compatible with USB 1.1. See pages 1-23 and 1-28 for details.

1.3.2

Innovative ASUS features

This feature allows you to restore the original BIOS data from the support CD in case when the BIOS codes and data are corrupted. This protection eliminates the need to buy a replacement ROM chip. See page 2-6 for details.

With the ASUS EZ Flash, you can easily update the system BIOS even before loading the operating system. No need to use a DOS-based utility or boot from a floppy disk. See page 2-3 for details.

This feature allows you to personalize and add style to your system with customizable boot logos. See page 2-36 for details.

The ASUS Q-Fan technology smartly adjusts the CPU fan speed according to the system loading to ensure quiet, cool, and efficient operation. See page 2-33 for details.

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.

1.4

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.

• B e f o r e y o u i n s t a l l o r r e m o v e a n y c o m p o n e n t , e n s u r e to do so may cause severe damage to the motherboard, peripherals, and/or components.

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.

C l e a r R T C R A M ( C L R T C )

This jumper allows you to clear the Real Time Clock (RTC) RAM in

CMOS. You can clear the CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in CMOS, which include system setup information such as system passwords.

To erase the RTC RAM:

1.

Turn OFF the computer and unplug the power cord.

2.

Remove the onboard battery.

3.

Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3 for about 5~10 seconds, then move the cap back to pins 1-2.

4.

Re-install the battery.

5.

Plug the power cord and turn ON the computer.

6.

Hold down the <Del> key during the boot process and enter BIOS setup to re-enter data.

BIOS setup program

This motherboard supports a programmable firmware chip that you can update using the provided utility described in section “ 2.1 Managing and updating your BIOS.”

Use the BIOS Setup program when you are installing a motherboard, reconfiguring your system, or prompted to “Run Setup.” This section explains how to configure your system using this utility.

Even if you are not prompted to use the Setup program, you can change the configuration of your computer in the future. For example, you can enable the security password feature or change the power management settings. This requires you to reconfigure your system using the BIOS

Setup program so that the computer can recognize these changes and record them in the CMOS RAM of the firmware hub.

The firmware hub on the motherboard stores the Setup utility. When you start up the computer, the system provides you with the opportunity to run this program. Press <Del> during the Power-On-Self-Test (POST) to enter the Setup utility; otherwise, POST continues with its test routines.

If you wish to enter Setup after POST, restart the system by pressing

<Ctrl+Alt+Delete>, or by pressing the reset button on the system chassis.

You can also restart by turning the system off and then back on. Do this last option only if the first two failed.

The Setup program is designed to make it as easy to use as possible. Being a menu-driven program, it lets you scroll through the various sub-menus and make your selections from the available options using the navigation keys.

• The default BIOS settings for this motherboard apply for most conditions to ensure optimum performance. If the system becomes unstable after changing any BIOS settings, load the default settings

Menu.”

• The BIOS setup screens shown in this section are for reference purposes only, and may not exactly match what you see on your screen.
