Make sure that you use only qualified heatsink and fan assembly.

• The retention module base is already installed on the motherboard

upon purchase.

• You do not have to remove the retention module base when

installing the CPU or installing other motherboard components.

• 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.

Your boxed CPU heatsink and fan assembly should come with installation

instructions for the CPU, heatsink, and the retention mechanism. If the

instructions in this section do not match the CPU documentation, follow

the latter.

1.5.11.5.1

1.5.1 OverviewOverview

OverviewOverview

Overview

The motherboard comes with four 184-pin Double Data Rate (DDR) Dual

Inline Memory Modules (DIMM) sockets.

The following figure illustrates the location of the sockets:

1.5.21.5.2

1.5.2 Memory ConfigurationsMemory Configurations

Memory ConfigurationsMemory Configurations

Memory Configurations

You may install 256 MB, 512 MB and 1 GB unbuffered or non-ECC DDR

DIMMs into the DIMM sockets using the memory configurations in this

section.

•

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).

•

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 DDR400 Qualified Vendors List

on the next page for details.

• Due to chipset resource allocation, the system may detect less than

4 GB of system memory when you installed four 1 GB DDR memory

modules.

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

double-sided x16 memory chips are not supported in this

motherboard.

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!

max.) or a total of 1A~3.48A (41.76 W max.) at +12V. Connect the

fan cables to the fan connectors on the motherboard, making sure that

the black wire of each cable matches the ground pin of the connector.

• Do not forget to connect the fan cables to the fan connectors. Lack

of sufficient air flow inside the system may damage the

motherboard components. These are not jumpers! DO NOT place

jumper caps on the fan connectors!

2.2 BIOS setup program

This motherboard supports a programmable Low-Pin Count (LPC) 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 LPC chip.

The LPC 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 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 LoadLoad

LoadLoad

Load

Default SettingsDefault Settings

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.
