Installing the CPU heatsink and fan

Installing the CPU heatsink and fanInstalling the CPU heatsink and fan

The Intel® Pentium® 4 LGA775 processor requires a specially designed
heatsink and fan assembly to ensure optimum thermal condition and
performance.

•

When you buy a boxed Intel® Pentium® 4 processor, the package
includes the CPU fan and heatsink assembly. If you buy a CPU
separately, make sure that you use only Intel®-certified
multi-directional heatsink and fan.

•

Your Intel® Pentium® 4 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.

The motherboard comes with four 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 figure illustrates the location of the DDR2 DIMM sockets:

You may install 256 MB, 512 MB, 1 GB, and 2 GB unbuffered ECC and
non-ECC DDR2 DIMMs into the DIMM sockets.

• For dual-channel configuration, the total size of memory module(s)
installed per channel must be the same (DIMM_A1 + DIMM_A2 =
DIMM_B1 + DIMM_B2).

• Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules
from the same vendor. Refer to the DDR2 Qualified Vendors List on
the next page for details.

2.5 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.

2.5.12.5.1

2.5.1

2.5.12.5.1

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 firmly 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.

2.5.22.5.2

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,
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.

Clear RTC RAM (CLRTC)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 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!

P5WD2-E

®

P5WD2-E PREMIUM Clear RTC RAM

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.

supply unit (PSU) that complies with ATX 12 V Specification 2.0 (or
later version) and provides a minimum power of 400 W.

•

Do not forget to connect the 8-pin/4-pin EATX12 V power plug;
otherwise, the system will not boot up.

•

Make sure that the PSU can support at least 8 A on the +12V_1
lead and 13 A on the +12V_2 lead.

•

The ATX 12 V Specification 2.0-compliant (400 W) PSU has been
tested to support the motherboard power requirements with the
following configuration:

CPU : Intel

®

Pentium® 4 3.73 GHz Extreme Edition
Memory : 512 MB DDR2 (x 4)
Graphics cards : 1 x PCIe x16 ATI CrossFire Edition card

1 x PCIe x16 ATI CrossFire-ready card
Parallel ATA device : IDE hard disk drive
Serial ATA device : SATA hard disk drive (x2)
Optical drives : DVD-RW

•

Use of a PSU with a higher power output is recommended when
configuring a system with more power consuming devices. The
system may become unstable or may not boot up if the power is
inadequate.

•

If you want to use two high-end PCI Express x16 graphics cards, use
a PSU with 450 to 500 W power to ensure system stability.

•

To support an Intel® Dual-Core CPU up to 840 Extreme Edition, make
sure that the PSU can provide at least DC 16A (peak 22A) on the
+12V_2 lead. The vendors list on the next page is provided for your
reference.

3.1 Starting up for the first time

1. After making all the connections, replace the system case cover.

2. Be sure that all switches are off.

3. Connect the power cord to the power connector at the back of the
system chassis.

4. Connect the power cord to a power outlet that is equipped with a
surge protector.

5. Turn on the devices in the following order:
a. Monitor
b. External SCSI devices (starting with the last device on the chain)
c. System power

6. After applying power, the system power LED on the system front
panel case lights up. For systems withATX power supplies, the system
LED lights up when you press the ATX power button. If your monitor
complies with “green” standards or if it has a “power standby”
feature, the monitor LED may light up or switch between orange and
green after the system LED turns on.

The system then runs the power-on self tests or POST. While the
tests are running, the BIOS beeps (see BIOS beep codes table below)
or additional messages appear on the screen. If you do not see
anything within 30 seconds from the time you turned on the power,
the system may have failed a power-on test. Check the jumper
settings and connections or call your retailer for assistance.

4.2 BIOS setup program

This motherboard supports a programmable firmware chip that you can
update using the provided utility described in section
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 or the firmware hub.

The firmware hub 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.

“

4.1 Managing and

If you wish to enter Setup after POST, restart the system by pressing
<Ctrl>+<Alt>+<Del>, or by pressing the reset button on the system
chassis. You can also restart by turning the system off and then back on.
Do this last option only if the first two failed.

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
Default SettingsDefault Settings

Default Settings item under the Exit Menu. See section “4.7 Exit

Default SettingsDefault Settings
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
file for this motherboard.
