2.4.2 Memory congurations

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

Important notice on installing Windows® XP 32-bit version

If you install Windows® XP 32-bit version Operating System (OS), the limitation
of this OS version is that it may reserve a certain amount of memory space for
system devices. We recommend that you install less than 3 GB system memory
if you would like to work under Windows® XP 32-bit version OS. The excess
memory installation will not cause any usage problem, but it will not give users

the benet of manipulating this excess memory space.

Visit the ASUS FAQ site for further
explanation:
http://support.asus.com/faq/faq.
aspx?SLanguage=en-us
Under General Search, make the
selections as shown, then click Search.
Click the article titled “4GB memory installed but less memory size
detected.”

You also may check the URLs below for third party comments on this issue:
http://dlsvr01.asus.com/pub/ASUS/mb/4GB_Rev1.pdf
http://www.intel.com/support/motherboards/server/sb/cs-016594.htm

• For dual-channel conguration, the total size of memory module(s) installed

per channel must be the same (DIMM_A1 + DIMM_B1 = DIMM_A2 +
DIMM_B2).

• Always install DIMMs with the same CAS latency. For optimum
compatibility, we recommend that you obtain memory modules from
the same vendor. Visit the ASUS website (www.asus.com) for the latest

Qualied Vendors List.

• When using only one DDR2 DIMM module, install it into slot DIMM_A1
only.

• For single-channel memory conguration, start installing the DDR2 DIMMs

from slot DIMM_A1 or DIMM_B1.

• For dual-channel memory conguration, install the DIMMs in slots
DIMM_B1 and DIMM_A1 (yellow slots); install another pair of DIMMs in

slots DIMM_B2 and DIMM_A2 (black slots).

GPUs.

• Due to NVIDIA nForce4 SLI x16 chipset limitations, this motherboard does
not support two dual-GPU graphics cards (total 4 GPUs) running in SLI
mode.

• Connect a rear chassis fan to the chassis (CHA_FAN1 or CHA_FAN2)

connector when using two graphics cards for better thermal environment.
See page 2-33 for details.

• In single card mode, you may use either the blue or black slot for PCI

Express x16 cards.

• In NVIDIA

®

SLI™ mode, the PCI Express x16 slots work at the full

bandwidth of PCI Express x16 for a combined bandwidth of x32.

• We recommend that you provide sufcient power when running NVIDIA

®

SLI™ mode. See page 2-31 for details.

2.6 Jumper

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. 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 remove the cap on CLRTC jumper
default position. Removing the cap will cause system boot failure!

• Make sure to re-enter your previous BIOS settings after you clear the
CMOS.

• 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.

4-10 Chapter 4: BIOS setup

4.2 BIOS setup program

This motherboard supports a programmable Low-Pin Count (LPC) chip that you
can update using the provided utility described in section “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

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 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 “4.8 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.
