2-8 Chapter 2: Hardware information

2.3.2 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®-certified 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.

2.4.1 Overview

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:

Channel Sockets

Channel A DIMM_A1 and DIMM_A2

Channel B DIMM_B1 and DIMM_B2

• The chipset officially supports the FSB up to 1066MHz.Tuned by the ASUS
exclusive technology, this motherboard supports up to FSB 1333MHz. See
the table below.

• When you are using
667 DIMMs or DDR2 800 DIMMs.

ASUS P5B SE 2-13

a CPU with FSB 1333MHz, make sure to install DDR2

2.4.2 Memory congurations

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

Mode

Single-Channel

Dual-channel (1)

Dual-channel (2)

• 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
configuration. 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 chipset resource allocation, the system may detect less than 8 GB
system memory when you installed four 2 GB DDR2 memory modules.

• This motherboard does not support memory modules made up of 128 Mb
chips or double sided x16 memory modules.

• If you install four 1 GB memory modules, the system may detect less than
3 GB of total memory because of address space allocation for other critical
functions. This limitation applies to Windows XP 32-bit version operating
system since it does not support PAE (Physical Address Extention) mode.

• If you install Windows XP 32-bit version operating system, we recommend
that you install less than 3GB of total memory.

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, but only DDR2-533 and DDR2-667 2 GB density
modules are available for this configuration.

2-14 Chapter 2: Hardware information

• 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.

2.4.3 Installing a DIMM

Make sure to unplug the power supply before adding or removing DIMMs or
other system components. Failure to do so may cause severe damage to both
the motherboard and the components.

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 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 fits 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.

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.

2.5.1 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 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.

2.5.2 Conguring an expansion card

After installing the expansion card, configure it by adjusting the software settings.

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.

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. 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.

Set these jumpers to +5V to wake up the computer from S1 sleep mode
(CPU stopped, DRAM refreshed, system running in low power mode) using
the connected USB devices. Set to +5VSB to wake up from S3 and S4 sleep
modes (no power to CPU, DRAM in slow refresh, power supply in reduced
power mode).

• The USB device wake-up feature requires a power supply that can
provide 500mA on the +5VSB lead for each USB port; otherwise,
the system would not power up.

• The total current consumed must NOT exceed the power supply
capability (+5VSB) whether under normal condition or in sleep mode.

3. Keyboard power (3-pin KBPWR)

This jumper allows you to enable or disable the keyboard wake-up feature.
Set this jumper to pins 2-3 (+5VSB) to wake up the computer when you press
a key on the keyboard (the default is the Space Bar). This feature requires
an ATX power supply that can supply at least 1A on the +5VSB lead, and a
corresponding setting in the BIOS.

4.2 BIOS setup program

This motherboard supports a programmable firmware chip that you can update
using the provided utility described in section “4.1 Managing and 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 of the
SPI chip.

The firmware 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 “4.8 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 file
for this motherboard.
