6. Apply several drops of thermal paste
to the exposed area of the CPU that
the heatsink will be in contact with,
ensuring that it is spread in an even
thin layer.

Some heatsinks come with pre­applied thermal paste. If so, skip
this step.

The Thermal Interface Material is toxic and inedible. If it gets into your eyes
or touches your skin, ensure to wash it off immediately, and seek professional
medical help.

To prevent contaminating the paste, DO NOT spread the paste with your nger

directly.

7. Close the load plate (A), then push
the load lever (B) until it snaps into
the retention tab.

1.6.2 Installling the CPU heatsink and fan

®

The Intel

Core™ 2 Quad / Core™2 Extreme / Core™ 2 Duo / Pentium

Celeron® dual-core / Celeron® processor require a specially designed heatsink and fan

assembly to ensure optimum thermal condition and performance.

• Install the motherboard to the chassis before you install the CPU fan and
heatsink assembly

• When you buy a boxed

Intel® Core™ 2 Quad / Core™2 Extreme / Core™
2 Duo / Pentium® dual-core / Celeron® dual-core / Celeron® processor,
the package includes the CPU fan and heatsink assembly. If you buy a
CPU separately, ensure that you use only Intel®-certied multi-directional
heatsink and fan.

• Your

Intel® Core™ 2 Quad / Core™2 Extreme / Core™ 2 Duo / Pentium®
dual-core / Celeron® dual-core / Celeron® LGA775 heatsink and fan
assembly comes in a push-pin design and requires no tool to install.

If you purchased a separate CPU heatsink and fan assembly, ensure that a
Thermal Interface Material is properly applied to the CPU heatsink or CPU
before you install the heatsink and fan assembly.

To install the CPU heatsink and fan

1.7.1 Overview

The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline Memory

Modules (DIMM) sockets.

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

Channel Sockets

Channel A DIMM_A

Channel B DIMM_B

1.7.2 Memory congurations

You may install 256 MB, 512 MB, 1 GB and 2 GB unbuffered non-ECC DDR2

DIMMs into the DIMM sockets.

• You may install varying memory sizes in Channel A and Channel B. The
system maps the total size of the lower-sized channel for the dual-channel
conguration. Any excess memory from the higher-sized channel is then

mapped for single-channel operation.

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

• When installing total memory of 4GB capacity or more, Windows 32-bit operation
system may only recognize less than 3GB. Hence, a total installed memory of

less than 3GB is recommended.

• This motherboard does not support memory modules made up of 128 Mb

chips.

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!

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, 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

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

• Press the reset button on the system chassis.

• Press the power button to turn the system off then back on.

<Ctrl>+<Alt>+<Del> simultaneously.

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.
