1-4 Chapter 1: Product introduction

1.3 .2 Inn ov at ive A SU S f ea tu res

Cra s hF r ee B IO S 2

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 4-5 for details.

ASU S Q - Fan te c hno l og y

The ASUS Q-Fan technology smartly adjusts the fan speeds according to

the system loading to ensure quiet, cool, and efcient operation.

ASU S M y Log o 2™

This new feature present in the motherboard allows you to personalize and
add style to your system with customizable boot logos. See page 4-37 for

details.

ASU S P O ST R ep o rte r ™

The motherboard offers a new exciting feature called the ASUS POST
Reporter™ to provide friendly voice messages and alerts during the
Power-On Self-Test (POST) informing you of the system boot status and
causes of boot errors, if any. The bundled Winbond Voice Editor software

lets you to customize the voice messages in different languages. See page

3-3 for details.

IEE E 1 3 94a sup p or t

The IEEE 1394a interface provides high-speed and exible PC connectivity

to a wide range of peripherals and devices compliant to the IEEE 1394a
standard. The IEEE 1394a interface allows up to 400 Mbps transfer rates
through simple, low-cost, high-bandwidth asynchronous (real-time) data
interfacing between computers, peripherals, and consumer electronic
devices such as camcorders, VCRs, printers, TVs, and digital cameras. See
pages 2-22 and 2-30 for details.

Tem p er a tur e , f an, an d vo l ta g e m o ni t ori n g

The CPU temperature is monitored by the ASIC (integrated in the Winbond
hardware monitor) to prevent overheating and damage. The system fan
rotations per minute (RPM) is monitored for timely failure detection. The
ASIC monitors the voltage levels to ensure stable supply of current for
critical components.

2.1 Before you proceed

Take note of the following precautions before you install motherboard
components or change any motherboard settings.

• Make sure that your power supply unit (PSU) can provide at least
the minimum power required by your system. See “8. ATX power
connectors” on page 2-25 for details.

• Unplug the power cord from the wall socket before touching any
component.

• Use a grounded wrist strap or touch a safely grounded object or
to 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.

2.4 System memory

2.4 .1 Ove rv ie w

The motherboard comes with eight 240-pin Double Data Rate II (DDR2)
Dual Inline Memory Modules (DIMM) sockets.

The following gure illustrates the location of the sockets:

2.4 .2 Mem or y Con fi gu rat io ns

You may install 256 MB, 512 MB, 1 GB, or 2GB registered ECC DDR2

533/667 DIMMs into the DIMM sockets using the memory congurations in

this section.

•

For dual-channel conguration, the total size of memory module(s)

installed per channel must be the same for better performance.
Single CPU:
DIMM_A1+DIMM_A2=DIMM_B1+DIMM_B2
Dual CPU:
DIMM_A1+DIMM_A2=DIMM_B1+DIMM_B2
DIMM_A3+DIMM_A4 =DIMM_B3+DIMM_B4

• Always install DIMMs with the same CAS latency. For optimum
compatibility, we recommend that you obtain memory modules from

the same vendor. Refer to the DDR2 Qualied Vendors List at the

ASUS web site.

4.2 BIOS setup program

This motherboard supports a programmable rmware chip that you can

update using the provided utility described in section “4.1 Managing and
updating your BIOS.”

Use the BIOS Setup program when you are installing a motherboard,

reconguring your system, or prompted to “Run Setup”. This section
explains how to congure your system using this utility.

Even if you are not prompted to use the Setup program, you can change

the conguration 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 recongure your system using the BIOS Setup
program so that the computer can recognize these changes and record
them in the CMOS RAM of the rmware hub.

The rmware 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> + <Del>, 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 rst 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
to ensure system compatibility and stability. Select the Load Setup
Defaults item under the Exit Menu. See section “4.7 Exit 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.

• Visit the ASUS website (www.asus.com) to download the latest BIOS

le for this motherboard.
