• The retention module base is already installed on the motherboard
upon purchase.
• You do not have to remove the retention module base when
installing the CPU or installing other motherboard components.
• If you purchased a separate CPU heatsink and fan assembly, make
sure that a Thermal Interface Material is properly applied to the CPU
heatsink or CPU before you install the heatsink and fan assembly.
Your boxed CPU heatsink and fan assembly should come with installation
instructions for the CPU, heatsink, and the retention mechanism. If the
instructions in this section do not match the CPU documentation, follow
the latter.
Make sure that you use only qualied heatsink and fan assembly.

2.4.1 Overview
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:
Channel Sockets
Channel A DIMM_A1 and DIMM_A2
Channel B DIMM_B1 and DIMM_B2
2.4.2 Memory congurations
You may install 256 MB, 512 MB, 1 GB, and 2GB unbuffered ECC/non-ECC
DDR2 DIMMs into the DIMM sockets.

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.
Visit the ASUS FAQ site for further
explanation:
http://support.asus.com/faq/faq.
aspx?SLanguage=en-us
Under General Search, make the
selections as shown, then click Search. Click the article titled “4GB
memory installed but less memory size detected.”
* For dual-channel memory conguration (2), you may:
• install identical DIMMs in all four sockets OR
• install an identical DIMM pair in DIMM_A1 and DIMM_B1 (yellow
sockets) and another identical DIMM pair in DIMM_A2 and
DIMM_B2 (black sockets)
* Always use identical DDR2 DIMM pairs for dual-channel model. For
optimum compatibility, we recommend that you obtain memory
modules from the same vendor. Visit the ASUS website (www.asus.
com) for the latest Qualied Vendors List.
This motherboard can support 8 GB physical memory on the operating systems
listed below. You may install a maximum of 2 GB DIMMs on each slot.

2.5 Expansion slots
In the future, you may need to install expansion cards. The following
sub-sections describe the slots and the expansion cards that they support.
2.5.1 Installing an expansion card
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.
2.5.2 Conguring an expansion card
After installing the expansion card, congure 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,
conicts will arise between the two PCI groups, making the system
unstable and the card inoperable.

2.6 Jumpers
1. Clear RTC RAM (CLRTC)
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.

2. USB device wake-up (3-pin USBPW12, USBPW34, USBPW56,
USBPW78)
Set these jumpers to +5V to wake up the computer from S1 sleep
mode (CPU stopped, DRAM refreshed, system running in low power
mode) using the connected USB devices. Set to +5VSB to wake up
from S3 and S4 sleep modes (no power to CPU, DRAM in slow refresh,
power supply in reduced power mode).
• The USB device wake-up feature requires a power supply that can
provide 500mA on the +5VSB lead for each USB port; otherwise,
the system would not power up.
• The total current consumed must NOT exceed the power supply
capability (+5VSB) whether under normal condition or in sleep mode.

4.2 BIOS setup program
This motherboard supports a programmable Low-Pin Count (LPC) 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,
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 LPC chip.
The LPC 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:
• R e sta r t us ing t he O S s t anda rd s h ut- d own proc e dur e .
• P r ess <Ctr l>+< Alt> + <De l > s i mult aneo u sly .
• P r ess the rese t bu t ton on t he s y ste m ch a ssis .
• P r ess the powe r bu t ton to t urn t he s yst e m of f th e n b a ck o n.
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 Default
Settings item under the Exit Menu. See section “4.8 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.
