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.

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 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 Ov er v ie w

The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline
Memory Modules (DIMM) sockets.

A DDR2 module has the same physical dimensions as a DDR DIMM but has
a 240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are
notched differently to prevent installation on a DDR DIMM socket.

The gure illustrates the location of the DDR2 DIMM sockets:

2.4 .2 Me mo r y co nf i gu ra ti o ns

You may install 128 MB, 256 MB, 512 MB and 1 GB unbuffered non-ECC
DDR2 DIMMs into the DIMM sockets.

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

installed per channel must be the same (DIMM_A1 + DIMM_A2 =
DIMM_B1 + DIMM_B2).

• Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules

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

the next page for details.

• This motherboard does not support memory modules made up of
128 Mb chips or double sided x16 memory modules.

completely seated on the slot.

5. Secure the card to the chassis with the screw you removed earlier.

6. Replace the system cover.

2.5 .2 Co nf i gu ri ng an e xp ans io n car d

After installing the expansion card, congure the it by adjusting the

software settings.

1. Turn on the system and change the necessary BIOS settings, if any.
See Chapter 4 for information on BIOS setup.

2. Assign an IRQ to the card. Refer to the tables on the next page.

3. Install the software drivers for the expansion card.

Make sure to unplug the power cord before adding or removing
expansion cards. Failure to do so may cause you physical injury and
damage motherboard components.

When using PCI cards on shared slots, ensure that the drivers support
“Share IRQ” or that the cards do not need IRQ assignments. Otherwise,

conicts will arise between the two PCI groups, making the system

unstable and the card inoperable. Refer to the table on the next page for
details.

2.6 Jumpers

1. C l e ar R T C RAM ( C L RTC)
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.

Except when clearing the RTC RAM, never remove the cap on CLRTC
jumper default position. Removing the cap will cause system boot failure!

You do not need to clear the RTC when the system hangs due to
overclocking. For system failure due to overclocking, use the C.P.R. (CPU
Parameter Recall) feature. Shut down and reboot the system so the BIOS
can automatically reset parameter settings to default values.

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 or 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 Tests (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 Default
Settings 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.
