1.7 .1 Ov er vie w
The motherboard comes with two 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:
Channel Sockets
Channel A DIMM_A1
Channel B DIMM_B1
1.7 .2 Me mo ry co nf igu ra ti ons
You may install 128MB, 256 MB, 512 MB and 1 GB unbuffered non-ECC
DDR2 DIMMs into the DIMM sockets.
• For dual-channel conguration, the size of memory module installed
per channel must be the same (DIMM_A1= DIMM_B1)
• 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 Qualied Vendors List on
page 1-17 for details.
• If you are installing only one DIMM module for a Single-channel
conguration, install the module on DIMM_B1.

Important notice on installing Windows® XP 32-bit version
If you install Windows® XP 32-bit version Operating System (OS), the
limitation of this OS version is that it may reserve a certain amount of
memory space for system devices. We recommend that you install less
than 3 GB system memory if you would like to work under Windows
®
XP
32-bit version OS. The excess memory installation will not cause any
usage problem, but it will not give users the benet of manipulating this
excess memory space.

To install an expansion card:
1. Before installing the expansion card, read the documentation that
came with it and make the necessary hardware settings for the card.
2. Remove the system unit cover (if your motherboard is already
installed in a chassis).
3. Remove the bracket opposite the slot that you intend to use. Keep
the screw for later use.
4. Align the card connector with the slot and press rmly until the card is
completely seated on the slot.
5. Secure the card to the chassis with the screw you removed earlier.
6. Replace the system cover.
1.8 .2 Co nf igu ri ng an e xp ans io n car d
After installing the expansion card, congure it by adjusting the software
settings.
1. Turn on the system and change the necessary BIOS settings, if any.
See Chapter 2 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.

This jumper allows you to clear the Real Time Clock (RTC) RAM in
CMOS. You can clear the CMOS memory of date, time by erasing the
CMOS RTC RAM data. The onboard button cell battery powers the RAM
data in CMOS.
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.

2.2 BIOS setup program
This motherboard supports a programmable rmware 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,
reconguring your system, or prompted to“Run Setup.” This section
explains how to congure your system using this utility.
Even if you are not prompted to use the Setup program, you can change
the conguration 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 recongure your system using the BIOS Setup
program so that the computer can recognize these changes and record
them in the CMOS RAM of the SPI chip.
The rmware chip 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, reboot the system by doing any of
the following procedures:
• Restart using the OS standard shut-down procedure.
• Press <Ctrl>+<Alt>+<Del> simultaneously.
• Press the reset button on the system chassis.
• Press the power button to turn the system off then back on.
Using the power button, reset button, or the <Ctrl>+<Alt>+<Del> keys
to force reset from a running operating system can cause damage to
your data or system. We recommend to always shut-down the system
properly from the operating system.
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 “2.8 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.
