assembly to ensure optimum thermal condition and performance.
•
When you buy a boxed Intel® processor, the package includes the CPU fan
and heatsink assembly. If you buy a CPU separately, make sure that you
use only Intel®-certied multi-directional heatsink and fan.
•
Your Intel® 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, make sure
that you have properly applied Thermal Interface Material to the CPU
heatsink or CPU before you install the heatsink and fan assembly.
Make sure that you have installed the motherboard to the chassis before you
install the CPU fan and heatsink assembly.
To install the CPU heatsink and fan:
1. Place the heatsink on top of the
installed CPU, making sure that
the four fasteners match the holes
on the motherboard.
Orient the heatsink and fan
assembly such that the CPU
fan cable is closest to the CPU
fan connector.

1.7.1 Overview
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:
1.7.2 Memory congurations
You may install 256 MB, 512 MB, 1 GB and 2 GB unbuffered non-ECC DDR2
DIMMs into the DIMM sockets.
• Always install DIMMs with the same CAS latency. For optimum compatibility,
it is recommended that you obtain memory modules from the same vendor.
• If you install two 1 or 2GB memory modules, the system may only recognize
less than 3GB because the address space is reserved for other critical
functions. This limitation appears on Windows® XP 32-bit operation system
which does not support Physical Address Extension (PAE).
®
• If you install Windows
than 3GB is recommended.
• This motherboard does not support memory modules made up of 128 Mb
chips or double sided x16 memory modules.

Notes on memory limitations
• Due to chipset limitation, this motherboard can only support up to
4 GB on the operating systems listed below. You may install a maximum of
2 GB DIMMs on each slot, but only DDR2-533 and DDR2-667 2 GB density
modules are available for this conguration.
32-bit 64-bit

®
XP Windows® XP x64 Edition
Windows® 2003 server Windows® 2003 server x64 Edition
• Some old-version DDR2-667 DIMMs may not match Intel®’s
On-Die-Termination (ODT) requirement and will automatically downgrade
to run at DDR2-533. If this happens, contact your memory vendor to check
the ODT value.
• Due to chipset limitation, DDR2-667 with CL=3 will be downgraded to run
at DDR2-533 by default setting. If you want to operate with lower latency,
adjust the memory timing manually. There will be 4MB reduction in total
memory when enabling ASUS Thermostat function under Single Channel
mode, and 8MB reduction under Dual Channel Mode.

1.8 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.
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.
1.8.1 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.
1.8.2 Conguring an expansion card
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.
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. Refer to the table on the next page for details.

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 •words.
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!

This jumper allows you to enable or disable the keyboard/mouse/USB device
wake-up feature. Set this jumper to +5V to wake up the computer from S1
sleep mode (CPU stopped, DRAM refreshed, system running in low power
mode) using the connected keyboard, mouse or 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.

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 “2.7 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.
