1.3 Central Processing Unit (CPU)

®

P5LD2-TVM SE/S

P5LD2-TVM SE/S CPU Socket 775

The motherboard comes with a surface mount LGA775 socket designed for the
Intel® Pentium®  processor in the 775-land package.

•

Your boxed Intel® Pentium®  LGA775 processor package should
come with installation instructions for the CPU, fan and heatsink assembly.
If the instructions in this section do not match the CPU documentation,
follow the latter.

• Upon purchase of the motherboard, make sure that the PnP cap is on the
socket and the socket pins are not bent. Contact your retailer immediately
if the PnP cap is missing, or if you see any damage to the PnP cap/socket
pins/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 pins resulting
from incorrect CPU installation/removal, or misplacement/loss/incorrect
removal of the PnP cap.

1.3.1 Installling the CPU

1.3.2 Installling the CPU heatsink and fan

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

• Install the motherboard to the chassis before you install the CPU fan and

heatsink assembly

®

• When you buy a boxed Intel
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

Pentium®  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
a Thermal Interface Material is properly applied to the CPU heatsink or CPU
before you install the heatsink and fan assembly.

To install the CPU heatsink and fan:

1. Place the heatsink on top of the

1.4.1 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
20-pin footprint compared to the 1-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:

1.4.2 Memory congurations

You may install 25 MB, 512 MB and 1 GB unbuffered non-ECC DDR2 DIMMs into
the DIMM sockets.

• 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 Qualied Vendors List on the next page
for details.

• Due to chipset resource allocation, the system may detect less than 2 GB
system memory when you installed two 1 GB DDR2 memory modules.

• This motherboard does not support memory modules made up of 12 Mb
chips or double sided x1 memory modules.

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.

1.5.1 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.

1.5.2 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 2 for information on BIOS setup.

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.

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 rmware hub.

The rmware 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.

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 Default
Settings item under the Exit Menu. See section “2.7 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 systembuilder website to download the latest BIOS le for

this motherboard and .
