Overview
The motherboard comes with two 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.

Memory configurations
You may install 256 MB, 512 MB, and 1 GB unbuffered non-ECC DDR2 DIMMs
into the DIMM sockets.
•
For dual-channel configuration, the total size of memory module(s) installed
per channel must be the same (DIMM_A1 = DIMM_B1).
•
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 DDR2 Qualified Vendors List on next page for
details.
•
This motherboard does not support memory modules made up of 128 Mb
chips or double-sided x16 memory modules. .

2.2
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.”
•
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 file for
this motherboard. Make sure to choose the right BIOS files according to the
version of your mother board. Refer to your Printed Circuit Board (PCB) for
version information.
