Technology. Refer to the Appendix for more information on these CPU features.

ASUS P5KPL-AM/PS 1-11

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, 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.

1.7 System memory

P5KPL-AM/PS

P5KPL-AM/PS 240-pin DDR2 DIMM sockets

DIMM_A1

DIMM_B1

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:

Channel Sockets

Channel A DIMM_A
Channel B DIMM_B

Install a memory module in DIMM_A slot to support the Intel® Quiet System
Technology and for optimum performance.

1-16 Chapter 1: Product introduction

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 you 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 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 DDR2-800 and DDR2-667 2 GB
density modules are available for this conguration.

Windows® XP Windows® XP x 64 Edition
Windows® Vista Windows® Vista x 64 Edition

• Some old-version DDR2-800 DIMMs may not match Intel®

On-Die-Termination (ODT) requirement and will automatically downgrade
to run at DDR-667. If this heppens, contact your memory vendor to check
to ODT value.

1.7.4 Installing a DIMM

Unplug the power supply before adding or removing DIMMs or other
system components. Failure to do so can cause severe damage to both the
motherboard and the components.

To install a DIMM:

1. Unlock a 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

1

the socket.

3. Firmly insert the DIMM into
the socket until the retaining
clips snap back in place and
the DIMM is properly seated.

• 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.

• The DDR2 DIMM sockets do not support DDR DIMMs. DO not install DDR
DIMMs to the DDR2 DIMM sockets.

1.7.5 Removing a DIMM

Follow these steps to remove a DIMM.

1. Simultaneously press the retaining
clips outward to unlock the DIMM.

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 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. 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.

1. Clear RTC RAM (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 •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!

• 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.

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 <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 “2.8 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.
