Make sure that you use only qualied heatsink and fan assembly.
• 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.

* 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.
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.

1.9 Jumpers
1. Clear R T C RA M ( CLRT 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. Reinstall 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.

from S3 and S4 sleep modes.
The USBPW12 and USBPW34 jumpers are for the rear USB ports. The
USBPW56 is for the WiFi-AP module. The USBPW78 and USBPW910
jumpers are for the internal USB connectors that you can connect to
additional USB ports.
• 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 will not power up.

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 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-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.
