2.3.1 DIMM sockets location

The system 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:

2.3.2 Memorycongurations

You may install 256 MB, 512 MB, 1 GB, and 2 GB unbuffered ECC or non-ECC

DDR2-533/667 DIMMs to the DIMM sockets.

• Always install DIMMs with the same CAS latency. For optimum compatibility,
it is recommended that you obtain memory modules from the same vendor.

Visit the ASUS website for an updated DDR2 Qualied Vendors List for this

motherboard.

• Due to chipset resource allocation, and depending on the number of
expansion cards installed, the following conditions may occur:

- the system may detect less than 8 GB system memory when
you installed four 2 GB DDR2 memory modules

- may show an available memory space of less than 4 GB when
you installed four 1 GB DDR2 memory modules

• Three DDR2 DIMMs installed into any three memory sockets will function in
Dual channel asymmetric mode.

• When installing a single or two DIMMs, install the modules on the blue slots

(DIMM_A1/DIMM_B1). Refer to the recommended memory conguration

table below.

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.

1. Clear RTC RAM (CLRTC1)

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 includes 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!

5.2 BIOS setup program

This motherboard supports a programmable rmware chip that you can update

using the provided utility described in section “5.1 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
rmware hub.

The rmware 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 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
Exit Menu. See section “5.8 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 le for

this motherboard.
