1.6.1 Installing the CPU

To install a CPU:

1. Locate the CPU socket on the motherboard.

Before installing the CPU, ensure that the socket box is facing towards you and the load

lever is on your left.

To prevent damage to the socket

pins, do not remove the PnP cap

unless you are installing a CPU.

2. Press the load lever with your thumb

(A), then move it to the left (B) until it is

released from the retention tab.

4. Lift the load plate with your thumb and

forenger to a 100º angle (4A), then

push the PnP cap from the load plate

window to remove (4B).

3. Lift the load lever in the direction of the

arrow to a 135º angle.

5. Position the CPU over the socket,

ensuring that the gold triangle is on the

bottom-left corner of the socket then t

the socket alignment key into the CPU

notch.

6. 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.

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.

Some heatsinks come with pre-

applied thermal paste. If so, skip this

step.

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.

The motherboard supports Intel®

LGA775 processors with the

Intel® Enhanced Intel SpeedStep®

Technology (EIST) and Hyper-

Threading Technology.

1.6.2 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®-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.

Ensure that you have installed the motherboard to the chassis before you install the CPU

fan and heatsink assembly.

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.

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.

2. Push down two fasteners at a time in a

diagonal sequence to secure the heatsink

and fan assembly in place.

3. Connect the CPU fan cable to the connector on the motherboard labeled CPU_FAN.

Do not forget to connect

the CPU fan connector!

Hardware monitoring errors

can occur if you fail to plug

this connector.

1.6.3 Uninstalling the CPU heatsink and fan

To uninstall the CPU heatsink and fan

1. Disconnect the CPU fan cable from

the connector on the motherboard.

2. Rotate each fastener

counterclockwise.

3. Pull up two fasteners at a time in

a diagonal sequence to disengage

the heatsink and fan assembly

from the motherboard.

4. Carefully remove the heatsink and fan assembly from the motherboard.

1.7 System memory

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:

1.7.2 Memory congurations

You may install 256MB, 512MB, 1GB and 2GB 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.

• 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 install a 64-bit

Windows OS when having 4GB or more memory installed on the motherboard.

• Due to chipset limitation, this motherboard only supports up to the total of four ranks (four

sides in total) of RAM at max.

• This motherboard does not support DIMMs made up of 256 megabit (Mb) chips or less.

• When using only one memory module, start installing the DDR2 DIMM from slot

DIMM_A1 or DIMM_B1 for better overclocking capability.

• For dual-channel conguration, you may:

- install identical DIMMs in all four sockets OR

- install 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 mode. For optimum

compatibility, we recommend that you obtain memory modules from the same vendor.

Failure to do so can cause severe damage to both the motherboard and the components.

1. Unlock a DDR2 DIMM

socket by pressing

the retaining clips

outward.

2. Align a DIMM on the

socket such that the

notch on the DIMM

matches the break on

A DDR2 DIMM is keyed with a notch so that it ts in only one direction. DO NOT force a

DIMM into a socket to avoid damaging the DIMM.

3. Firmly insert the DIMM into the socket

until the retaining clips snap back in place

and the DIMM is properly seated.

1.7.4 Removing a DIMM

To remove a DIMM:

1. Simultaneously press the retaining clips

outward to unlock the DIMM.

2. Remove the DIMM from the socket.

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.

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.

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 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 2 for

information on BIOS setup.

2. Assign an IRQ to the card.

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.

1.8.4 PCI slots

The PCI slots support cards such as a LAN card, SCSI card, USB card, and other cards that

comply with PCI specications.

1.8.5 PCI Express x1 slot

This motherboard supports PCI Express x1 network cards, SCSI cards and other cards that

comply with the PCI Express specications.

1.8.6 PCI Express x16 slot

This motherboard supports a PCI Express x16 graphics card that complies with the PCI

Express specications.

1-18 Chapter 1: Product introduction

1.9 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. 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.

3. Plug the power cord and turn ON the computer.

4. 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!

• If the steps above do not help, remove the onboard battery and move the jumper again

to clear the CMOS RTC RAM data. After the CMOS clearance, reinstall the battery.

• You do not need to clear the RTC when the system hangs due to overclocking. For

system failure due to overclocking, use the CPU Parameter Recall (C.P.R.) feature. Shut

1. Insert a USB ash disk that contains BIOS le to the USB port.

2. Turn on the system.

3. The utility will automatically checks the devices for the BIOS le When found, the utility

reads the BIOS le and starts ashing the corrupted BIOS le.

4. Restart the system after the utility completes the updating process.

• Only the USB ash disk with FAT 32/16 format and single partition can support ASUS

CrashFree BIOS 3. The device size should be smaller than 8GB.

• DO NOT shut down or reset the system while updating the BIOS! Doing so can cause

system boot failure!

ASUS P5QL-EM 2-7

2.2 BIOS setup program

This motherboard supports a programmable Serial Peripheral Interface (SPI) 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 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 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 at www.asus.com to download the latest BIOS le for this

motherboard.
