Connect the chassis fan cable to the CHA_FAN connector to ensure

system stability.

•

Upon purchase of the motherboard, make sure that the PnP cap is on

the socket and the socket contacts are not bent. Contact your retailer

immediately if the PnP cap is missing, or if you see any damage to the PnP

cap/socket contacts/motherboard components. ASUS will shoulder the cost

of repair only if the damage is shipment/transit-related.

•

Keep the cap after installing the motherboard. ASUS will process Return

Merchandise Authorization (RMA) requests only if the motherboard comes

with the cap on the LGA775 socket.

The product warranty does not cover damage to the socket contacts

resulting from incorrect CPU installation/removal, or misplacement/loss/

incorrect removal of the PnP cap.

Apply several drops of Thermal

Interface Material 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 pre-

applied thermal paste. If so, skip

this step.

DO NOT eat the Thermal Interface Material. If it gets into your eyes or touches

your skin, ensure that you wash it off immediately, and seek professional

medical help.

To prevent contaminating the paste, DO NOT spread the paste with your ﬁnger

directly.

2.3.2

Installing the CPU heatsink and fan

The Intel^®LGA775 processor requires a specially designed heatsink and fan

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, ensure that you use

only Intel^®-certiﬁed 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.

Ensure 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:

Place the heatsink on top of the

installed CPU, making sure that the

four fasteners match the holes on

the motherboard.

Push down two fasteners at a time in

a diagonal sequence to secure the

heatsink and fan assembly in place.

The type of CPU heatsink and fan assembly may differ, but the installation steps

and fucntions should remain the same. The illustration above is for reference

only.

Uninstalling the CPU heatsink and fan

To uninstall the CPU heatsink and fan

Disconnect the CPU fan cable from

the connector on the motherboard.

Rotate each fastener

counterclockwise.

Pull up two fasteners at a time in a

diagonal sequence to disengage the

heatsink and fan assembly from the

motherboard.

Carefully remove the heatsink and fan assembly from the motherboard.

Overview

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

Modules (DIMM) sockets.

Chapter 2: Hardware information

•

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

conﬁguration. 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.

Due to the memory address limitation on 32-bit Windows^®OS, when you

install 4GB or more memory on the motherboard, the actual usable memory

for the OS can be about 3GB or less. For effective use of memory, we

recommend that you do any of the following:

•

Use a maximum of 3GB system memory if you are using a 32-bit Windows^®

OS.

Install a 64-bit Windows^®OS when you want to install 4GB or more memory

on the motherboard.

This motherboard does not support DIMMs made up of 256 megabits (Mb)

chips or less.

•

The default memory operation frequency is dependent on its SPD. Under

the default state, some memory modules for overclocking may operate at a

lower frequency than the vendor-marked value. To operate at the vendor-

marked or at a higher frequency, see section 4.4 Ai Tweaker menu for

manual memory frequency adjustment.

•

The memory modules may require a better cooling system to work stably

under full loading (4 DIMMs) or overclocking setting.

Some old-version DDR2-800 DIMMs may not match Intel^®’s

On-Die-Termination (ODT) requirement and will automatically downgrade

to run at DDR2-667. If this happens, contact your memory vendor to check

the ODT value.

•

Due to chipset limitation, DDR2-800 with CL=4 will be downgraded to run

at DDR2-667 by default setting. If you want to operate with lower latency,

adjust the memory timing manually.

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.

Ensure to unplug the power cord before adding or removing expansion cards.

Failure to do so may cause you physical injury and damage motherboard

components.

2.5.1

Installing an expansion card

To install an expansion card:

Before installing the expansion card, read the documentation that came with

it and make the necessary hardware settings for the card.

Remove the system unit cover (if your motherboard is already installed in a

chassis).

Remove the bracket opposite the slot that you intend to use. Keep the screw

for later use.

Align the card connector with the slot and press ﬁrmly until the card is

completely seated on the slot.

Secure the card to the chassis with the screw you removed earlier.

Replace the system cover.

2.5.2

Conﬁguring an expansion card

After installing the expansion card, conﬁgure it by adjusting the software settings.

Turn on the system and change the necessary BIOS settings, if any. See

Chapter 4 for information on BIOS setup.

Assign an IRQ to the card. Refer to the tables on the next page.

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, conﬂicts 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.

BIOS setup program

This motherboard supports a programmable Serial Peripheral Interface (SPI) 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, reconﬁguring

your system, or prompted to “Run Setup.” This section explains how to conﬁgure

your system using this utility.

Even if you are not prompted to use the Setup program, you can change the

conﬁguration 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 reconﬁgure 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 SPI 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 Setups Default item under the

Exit Menu. See section 4.9 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.

(e.g. move the cable from LAN1 to LAN2), you may need to press the “Refresh”

button to detect the change.

•

The most common scenario is for your computer to automatically obtain

network settings (i.e. DHCP). If this is the case, you don’t need to click Setup

for any LAN port. If this is not the case, click Setup to conﬁgure the static IP

settings manually.

If you have wireless network, click Setup for the WiFi option. In the WiFi tab of

the Advanced Network Settings box, enter the name of your wireless access

point in the SSID ﬁeld. If your wireless access point has security enabled,

select the corresponding security algorithm from the drop-down list (e.g.

WEPAUTO) in the Encryption Type ﬁeld, and enter the password.

Click OK to enable WiFi and establish the wireless connection.

If you use a network cable connected directly to your DSL/cable modem (no

router in between), click Setup for xDSL/cable dial-up. This method is also

referred to as PPPoE. Choose whether the DSL/cable modem is connected

to your computer’s LAN port. Then enter the username and password for your

dial-up account.

Click OK to enable xDSL/cable dial-up and establish the PPPoE connection.

When PPPoE is enabled, the port it uses will automatically be unchecked and

grayed out.
