1-2 Chapter 1: Product Introduction

Native DDR2 1066 memory support

To attain top performance, ASUS engineers have successfully unleashed the

true potential of DDR2 memory. While in DDR2 1066 mode, ASUS’s exclusive

technology offers a choice of FSB 1333, providing great performance for 3D
graphics and other memory demanding applications. See page 2-19 for details.

Dual-channel DDR2 800 memory support

The motherboard supports DDR2 memory that features data transfer rates of

800/667 MHz to meet the higher bandwidth requirements of the latest 3D graphics,

multimedia, and Internet applications. The dual-channel DDR2 architecture
doubles the bandwidth of your system memory to boost system performance,
eliminating bottlenecks with peak bandwidths of up to 12.8 GB/s. Furthermore, this

motherboard does not restrict the memory size across two channels. Users may
install different memory size DIMMs into the two channels and enjoy dual-channel
and single-channel functions at the same time. This new feature optimizes the use
of available memory size. See page 2-19 for details.

ASUS Super Memspeed Technology

To attain top performance, ASUS has managed to break through current FSB

and DRAM ratio proportions by utilizing Super Memspeed Technology–the latest

technology that provides even more precise overclocking options to unleash the

true potential of DDR2 memory. The DDR2 Mode maximizes system performance
by eliminating the bottleneck when overclocking both the CPU and memory–

providing great performance for 3D graphics and other memory demanding

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.

• If you install four 1 GB memory modules, the system may only recognize less

than 3GB because the address space is reserved for other critical functions.
This limitation appears on Windows® XP/Vista 32-bit operation system which
does not support Physical Address Extension (PAE).

• If you install Windows
less than 3GB is recommended.

• This motherboard does not support memory modules made up of 128 Mb
chips.

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 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.

2.5.2 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 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, 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 (Gaming Level Switch Design)

This switch 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 switch from Disable (default) to Enable. Keep the switch on
Enable for about 5~10 seconds, then move the switch back to Disable.

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 move the CLRTC switch from its
default position, or the system will encounter 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.

4.2 BIOS setup program

This motherboard supports a programmable Serial Peripheral Interface (SPI) chip
that you can update using the provided utility described in section 4.1 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.

ASUS P5E

• 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 4.9 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.
