Production Introduction
1.1 Before you Proceed
Take note of the following precautions before you install motherboard components or
change any motherboard settings.
Unplug the power cord from the wall socket before touching any
component.
Use a grounded wrist strap or touch a safely grounded object or a
metal object, such as the power supply case, before handling
components to avoid damaging them due to static electricity
Hold components by the edges to avoid touching the ICs on
them.
Whenever you uninstall any component, place it on a grounded
antistatic pad or in the bag that came with the component.
Before you install or remove any component, ensure that the ATX
power supply is switched off or the power cord is detached from
the power supply. Failure to do so may cause severe damage to
the motherboard, peripherals, and/or components.

1.2 Motherboard Overview
Before you install the motherboard, study the configuration of your chassis to ensure that
the motherboard fits into it. Refer to the chassis documentation before installing the
motherboard.
Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so can cause you physical injury and
damage motherboard components.
1.2.1 Placement Direction
When installing the motherboard, make sure that you place it into the chassis in the correct
orientation. The edge with external ports goes to the rear part of the chassis as indicated in
the image below.
1.2.2 Screw Holes
Place four (4) screws into the holes indicated by circles to secure the motherboard to the
chassis.
Do not over tighten the screws! Doing so can damage the
motherboard.
Place this side towards the rear of the
chassis.

1.4 System Memory
1.4.1 DIMM Sockets Location
The motherboard comes with two 200-pin Double Data Rate 3 (DDR3) SODIMM sockets.
A DDR3 module has the same physical dimensions as a DDR2 DIMM but has a 204-pin
footprint compared to the 200-pin DDR DIMM. DDR3 DIMMs are notched differently to
prevent installation on a DDR2 DIMM socket. The following figure illustrates the location of
the sockets:
1.4.2 Memory Configurations
You can install 1GB and 2GB DDR3 SDRAM DIMMs into the SODIMM sockets using the
memory configurations in this section.
Installing DDR3 DIMM other than the recommended
configurations may cause memory sizing error or system boot
failure. Use any of the recommended configurations.
Due to chipset graphic resource allocation, the system may
detect less than 2 GB system memory when you installed one 2
GB DDR3 memory modules.
This motherboard does not support memory modules FSB less
than 1066MHz.Make sure that the memory frequency matches
the CPU FSB (Front Side Bus). Refer to the Memory
frequency/CPU FSB synchronization table.

User’s Manual

1.4.3 Installing a DDR3 DIMM
Make sure to unplug the power supply before adding or removing
DIMMs or other system components. Failure to do so may cause
severe damage to both the motherboard and the components.
1. Locate the DIMM socket on the board.
2. Hold two edges of the DIMM module carefully, and keep away of touching its
connectors.
3. Align the notch key on the module with the rib on the slot.
4. Firmly press the modules into the socket which will automatically snap into the mounting
notch. Do not force the DIMM module in with extra force as the DIMM module only fits in
one direction.
A DDR3 DIMM is keyed with a notch so that it fits in only one
direction. DO NOT force a DIMM into a socket to avoid damaging
the DIMM.
The DDR3 DIMM sockets do not support DDR/DDR2 DIMMs.
DO NOT install DDR/DDR2 DIMMs to the DDR3 DIMM socket.

1.4.4 Removing a DDR3 DIMM
1. Press the two ejector tabs on the slot outward simultaneously, and then pull out the
DIMM module.
Support the DIMM lightly with your fingers when pressing the ejector
tabs. The DIMM might get damaged when it flips out with extra force.

1.5 Expansion slots
1.5.1 MiniPCE Express Location
In the future, you may need to install expansion cards. The following sub-sections describe
the slots and the expansion cards that they support.
Make sure to unplug the power cord before adding or removing
expansion cards. Failure to do so may cause you physical injury and
damage motherboard components.
1.5.2 Installing an Expansion Card
1. Before installing the expansion card, read the documentation that came with it and
make the necessary hardware settings for the card.
2. Remove the system unit cover (if your motherboard is already installed in a chassis).
3. Remove the bracket opposite the slot that you intend to use. Keep the screw for later
use.
4. Align the card connector with the slot and press firmly until the card is completely seated
on the slot.
5. Secure the card to the chassis with the screw you removed earlier.
6. Replace the system cover.
1.5.3 Configuring an Expansion Card
After installing the expansion card, configure it by adjusting the software settings.
1. Turn on the system and change the necessary BIOS settings, if any. See Chapter 2 for
information on BIOS setup.
2. Assign an IRQ to the card if needed. Refer to the tables on the next page.
3. Install the software drivers for the expansion card.

NX260N

1.5.4 MiniPCI express slot
The miniPCI express slot supports Mini cards for WiFi , Bluetooth, SSD, COM, USB
modules, and other cards that comply with the mini Card Rev. 1.2 specifications . The figure
below shows the type of full size SSD card that can be installed on a miniPCI express slot.
Due to different pin definitions between mini Card Rev. 1.0 to 1.1/1.2 ,
some Rev.1.0 mini Cards may not work normally on this MiniPCI express
slot .
1.6 Jumpers
1.6.1 Clear CMOS (JCOMS1)
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 CMOS, never remove the cap on the
CLRTC jumper default position. Removing the cap will cause system
boot failure!
