2.4 System memory
2.4.1 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:
N4L-VM DH
®
N4L-VM DH 240-pin DDR2 DIMM sockets
2.4.2 Memory configurations
You may install 256 MB, 512 MB, and 1 GB non-ECC unbuffered DDR2
DIMMs into the DIMM sockets.
•
Always install DIMMs with the same CAS latency. For optimum
compatibility, we recommend that you obtain memory modules from
the same vendor. Refer to the DDR2 Qualified Vendors List on the
next page for details.
•
This motherboard does not support memory modules made up of
2048 Mb chips or double sided x16 memory modules.

2.6 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. 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.

4.2 BIOS setup program
This motherboard supports a programmable firmware 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,
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 or 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 “4.7 Exit
Menu.”
