System memory

1.7.1 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:

1.7.2 Memory Configurations

•

IF you installed four 1GB memory modules, the system may detect

less than 3GB 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 Extension) mode.

•

IF you install Windows XP 32-bit version operating system, we

recommend that you install less than 3GB of total memory.

For dual-channel configuration, the total size of memory module(s)

installed per channel must be the same for better performance

(DIMM_A1+DIMM_A2=DIMM_B1+DIMM_B2).

1-16

Chapter 1: Product introduction

•

When using one DDR DIMM module, install into DIMM_B1 slot only.

When using two DDR DIMM modules, install into DIMM_A1 and

DIMM_B1 slots only.

•

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 memory Qualified Vendors List

on the next page for details.

•

Due to CPU limitation, DIMM modules with 128 Mb memory chips or

double-sided x16 memory chips are not supported in this motherboard.

1.7.3 DDR2 Qualified Vendors List

Jumpers

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!

(Default)

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.

BIOS setup program

This motherboard supports a programmable firmware 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,

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 firmware hub.

The firmware 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 first 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.”
