2.4.1 Overview

The motherboard comes with four Double Data Rate II (DDR2) Dual Inline Memory
Modules (DIMM) sockets to support 240-pin DDR2 modules.

The gure illustrates the location of the DDR2 DIMM sockets:

Channel Sockets

Channel A DIMM_A1 and DIMM_A2
Channel B DIMM_B1 and DIMM_B2

This chipset ofcially supports DDR2 800/667MHz. With the ASUS Super
Memspeed Technology, the motherboard natively supports up to DDR2
1066MHz and provides more ratio setting items than the chipset ofcially

supports. Refer to the table below for details.

FSB 1333 1066

DDR2 1066 800 667 1066 800 667

Chapter 2: Hardware setup2-10

2.4.2 Memorycongurations

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

• 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, it is recommended that you obtain memory modules from the
same vendor.

• If you install four 1GB memory modules, the system may only recognize
less than 3GB of total memory because of address space allocation for
other critical functions. This limitation appears on Windows® Vista 32-bit /
Windows® XP 32-bit operation systems since it does not support Physical

Address Extension (PAE) mode.

• If you install Windows® Vista 32-bit / Windows® XP 32-bit operation system,
a total memory of less than 3GB is recommended.

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

• 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 DIMMs may not match Intel®’s

On-Die-Termination (ODT) requirement and will automatically downgrade

to run at DDR2-667. 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.

2-11ASUS TW300-E5/PI4

2.4.3 Installing a DIMM

Unplug the power supply before adding or removing DIMMs or other
system components. Failure to do so can cause severe damage to both the
motherboard and the components.

To install a DIMM:

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 ts 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.

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. 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.

3. Plug the power cord and turn ON the computer.

4. 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!

If the steps above do not help, remove the onboard battery and move the
jumper again to clear the CMOS RTC RAM data. After the CMOS clearance,
reinstall the battery.

4.2 BIOS setup program

This motherboard supports a programmable rmware 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 rmware 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 Default Settings 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.

• Visit the ASUS website (www.asus.com) to download the latest BIOS le for

this motherboard.
