2.1 Before you proceed

Take note of the following precautions before you install motherboard components

or change any motherboard settings.

Unplug the power cord from the wall socket before touching any

component.

Use a grounded wrist strap or touch a safely grounded object or a metal

object, such as the power supply case, before handling components to

avoid damaging them due to static electricity.

Hold components by the edges to avoid touching the ICs on them.

Whenever you uninstall any component, place it on a grounded antistatic

pad or in the bag that came with the component.

Before you install or remove any component, ensure that the ATX power

supply is switched off or the power cord is detached from the power

supply. Failure to do so may cause severe damage to the motherboard,

peripherals, and/or components.

Onboard LED

The motherboard comes with a standby power LED that lights up to indicate that

the system is ON, in sleep mode, or in soft-off mode. This is a reminder that you

should shut down the system and unplug the power cable before removing or

plugging in any motherboard component. The illustration below shows the location

of the onboard LED.

Make sure that all power cables are unplugged before installing the CPU.

Connect the chassis fan cable to the CHA_FAN1 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.

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, make sure that you

®

use only Intel

-certied 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.

2.4 System memory

2.4.1 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_A1 and DIMM_A2

Channel B DIMM_B1 and DIMM_B2

DIMM_B1

DIMM_B2

P5K 240-pin DDR2 DIMM sockets

This chipset ofcially supports DDR2-800 MHz. With the ASUS Super

Memspeed Technology, this motherboard natively supports up to

DDR2-1066 MHz. See the table below.

FSB DDR2

1333 1066*

1333 800

1333 667

1066 1066*

1066 800

1066 667

*If you install a DDR2-1066 memory module whose SPD is DDR2-800,

make sure that you set the DRAM Frequency item in BIOS to

[DDR2-1066MHz]. See section 4.4.1 Jumperfree Conguration for

details.

2.4.2 Memory congurations

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

DIMMs into the DIMM sockets.

Recommended Memory Congurations

Sockets

Mode

DIMM_A1 DIMM_B1 DIMM_A2 DIMM_B2

- Populated - -

Single-Channel

Populated - - -

Dual-channel (1) Populated Populated - -

Dual-channel (2) Populated Populated Populated Populated

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.

If you install four 1 GB 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/Vista 32-bit operation system which

does not support Physical Address Extension (PAE).

®

If you install Windows

XP/Vista 32-bit operation system, a total memory of

less than 3GB is recommended.

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

chips.

Notes on memory limitations

Due to chipset limitation, this motherboard can only support up to

8 GB on the operating systems listed below. You may install a maximum of

2 GB DIMMs on each slot.

64-bit

®

Windows

XP Professional x64 Edition

®

Windows

Vista x64 Edition

®

Some old-version DDR2-800/667 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.

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.

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 Conguring an expansion card

After installing the expansion card, congure 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.

When using PCI cards on shared slots, ensure that the drivers support “Share

IRQ” or that the cards do not need IRQ assignments. Otherwise, conicts 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.

This motherboard also supports a Universal PCI-E slot with a maximum speed of 2

GB/s. The operating frequency of this slot changes, depending on the type of PCI

Express card you install. Refer to the table below for details.

If you install two VGA cards, we recommend that you plug the rear chassis

fan cable to the motherboard connector labeled CHA_FAN1 for better thermal

environment. See page 2-34 for the connector location.

Options for Universal PCI Express slot PCI Express operating speed

Auto Automatically optimizes performance and

functionality according to devices installed.

x4 mode [fast] User gets the best performance but this

mode disables the PCI Express x1 slot.

x2 mode [compatible] Always runs at PCI Express x2 speed.

Some PCI Express graphics cards cannot operate on x4/x2 mode. We suggest

that you install these cards on the primary PCI Express slot (blue) to increase

system stability.

2.6 Jumper

1. Clear RTC RAM (3-pin 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. 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.

Due to the chipset limitation, AC power off is required prior using C.P.R.

function. You must turn off and on the power supply or unplug and plug the

power cord before reboot the system.
