Production Introduction
1.1 Before you Proceed
Take note of the following precautions before you install motherboard components or
change any motherboard settings.
zUnplug the power cord from the wall socket before touching any
component.
zUse 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
zHold components by the edges to avoid touching the ICs on
them.
zWhenever you uninstall any component, place it on a grounded
antistatic pad or in the bag that came with the component.
zBefore 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 2 (DDR2) SODIMM sockets.
A DDR2 module has the same physical dimensions as a DDR DIMM but has a 200-pin
footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are notched differently to
prevent installation on a DDR DIMM socket. The following figure illustrates the location of
the sockets:

ENX-US15WP
18
1.4.2 Memory Configurations
You can install 256MB, 512MB, 1GB and 2GB DDR2 SDRAM DIMMs into the SODIMM
sockets using the memory configurations in this section.
zInstalling DDR2 DIMM other than the recommended
configurations may cause memory sizing error or system boot
failure. Use any of the recommended configurations.
zDue to chipset resource allocation, the system may detect less
than 1 GB system memory when you installed one 1 GB DDR2
memory modules.
zThis motherboard does not support memory modules made up of
128 Mb chips or single-sided x8 memory modules.
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
ENX-US15WP
19
1.4.3 Installing a DDR2 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 automatically snaps into the mounting notch.
Do not force the DIMM module in with extra force as the DIMM module only fit in one
direction.
zA DDR2 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.
zThe DDR2 DIMM sockets do not support DDR DIMMs. DO NOT
install DDR DIMMs to the DDR2 DIMM socket.

ENX-US15WP

1.4.4 Removing a DDR2 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.
