Take note of the following precautions before you install components into the
system.

• Unplug the power cables before you touch any component in the system.

•

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 cable is detached from the power
supply. Failure to do so may lead to personal injury and cause severe
damage to the motherboard, peripherals, and components.

Onboard LED

The system 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 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.

2.4.1 Overview

The motherboard comes with a surface mount LGA775 socket designed for the
Intel® Core™2 Quad / Intel® Core™2 Extreme / Core™2 Duo / Pentium® Extreme /
Pentium® D/ Pentium® 4 / Celeon® processors.

• 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.

2.4.2 Installing CPU

To install a CPU:

1. Locate the CPU socket on the motherboard.

Before installing the CPU, make sure that the socket box is facing towards you
and the load lever is on your left.

2-5ASUS V4-Series P5G43

2. Press the load lever with your thumb

(A), then move it to the left (B) until it
is released from the retention tab.

To prevent damage to the
socket pins, do not remove
the PnP cap unless you are
installing a CPU.

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.

Some heatsinks come with
preapplied 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 thermal paste, DO NOT spread it 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.

2-7ASUS V4-Series P5G43

2.4.3 Installing the CPU fan and heatsink assembly

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®-certied multi-directional heatsink and
fan.

®

• Your Intel
push-pin design and requires no tool to install.

• 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,
we recommend 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.

2-11ASUS V4-Series P5G43

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.

• 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.

• Due to chipset limitation, DDR2-667 with CL=3 will be downgraded to run
at DDR2-533 by default setting. If you want to operate with lower latency,

adjust the memory timing manually.

2.6 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.

2.6.1 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. The gure shows a LAN

card installed on a PCI slot.

2.6.2 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. The gure shows

a network card installed on the PCI
Express x1 slot.

2.6.3 PCI Express x16 slot

This motherboard supports PCI Express

x16 graphic cards that comply with the
PCI Express specications. The gure

shows a graphics card installed on the

PCI Express x16 slot.

2.6.5 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.

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 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. Re-install 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.

These connectors are for ATX power supply plugs. The power supply plugs

are designed to t these connectors in only one orientation. Find the proper
orientation and push down rmly until the connectors completely t.

•

For a fully congured system, we recommend that you use a power supply

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

• Do not forget to connect the 4-pin EATX12V power plug; otherwise, the

system will not boot.

• Use of a PSU with a higher power output is recommended when

conguring a system with more power-consuming devices. The system

may become unstable or may not boot up if the power is inadequate.

• The ATX 12 V Specication 2.0-compliant (400W) PSU has been tested

to support the motherboard power requirements with the following
conguration:

CPU: Intel® Pentium® Extreme 3.73GHz

Memory: 512 MB DDR2 (x4)
Graphics card: ASUS EAX1900XT

Parallel ATA device: IDE hard disk drive
Serial ATA device: SATA hard disk drive (x2)
Optical drive: DVD-RW

• If you want to use two high-end PCI Express x16 cards, use a PSU with
500W to 600W power or above to ensure the system stability.

5.2 BIOS setup program

This motherboard supports a programmable Serial Peripheral Interface (SPI) chip
that you can update using the provided utility described in section “5.1 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, restart the system by pressing

<Ctrl+Alt+Delete>, 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 rst 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 Load Setups Default item under the
Exit Menu. See section 5.8 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.
