FCC and DOC Statement on Class B
This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a residential
installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined
by turning the equipment off and on, the user is encouraged to try
to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
• Consult the dealer or an experienced radio TV technician for
help.
Notice:
1. The changes or modifications not expressly approved by the
party responsible for compliance could void the user's authority
to operate the equipment.
2. Shielded interface cables must be used in order to comply with
the emission limits.

Introduction
Static Electricity Precautions
It is quite easy to inadvertently damage your PC, system board,
components or devices even before installing them in your system
unit. Static electrical discharge can damage computer components
without causing any signs of physical damage. You must take extra
care in handling them to ensure against electrostatic build-up.
1. To prevent electrostatic build-up, leave the system board in its
anti-static bag until you are ready to install it.
2. Wear an antistatic wrist strap.
3. Do all preparation work on a static-free surface.
4. Hold the device only by its edges. Be careful not to touch any of
the components, contacts or connections.
5. Avoid touching the pins or contacts on all modules and connectors. Hold modules or connectors by their ends.
Important:
Electrostatic discharge (ESD) can damage your processor,
disk drive and other components. Perform the upgrade instruction procedures described at an ESD workstation
only. If such a station is not available, you can provide
some ESD protection by wearing an antistatic wrist strap
and attaching it to a metal part of the system chassis. If a
wrist strap is unavailable, establish and maintain contact
with the system chassis throughout any procedures requiring ESD protection.
Safety Measures
To avoid damage to the system:
• Use the correct AC input voltage range
To reduce the risk of electric shock:
• Unplug the power cord before removing the system chassis
cover for installation or servicing. After installation or servicing,
cover the system chassis before plugging the power cord.
..
.
..
Battery:
• Danger of explosion if battery incorrectly replaced.
• Replace only with the same or equivalent type recommend
the manufacturer.
• Dispose of used batteries according to local ordinance.

Hardware Installation
Warning:
Electrostatic discharge (ESD) can damage your system board, processor, disk drives, add-in boards, and other components. Perform the
upgrade instruction procedures described at an ESD workstation only.
If such a station is not available, you can provide some ESD protection by wearing an antistatic wrist strap and attaching it to a metal
part of the system chassis. If a wrist strap is unavailable, establish
and maintain contact with the system chassis throughout any procedures requiring ESD protection.
System Memory
Warning:
When the DRAM Power LED lit red, it indicates that power is
present on the DIMM socket. Power-off the PC then unplug the
power cord prior to installing the memory module. Failure to do so
will cause severe damage to the motherboard and components.

Installing the DIM Module
Note:
The system board used in the following illustrations may not
resemble the actual one. These illustrations are for reference
only.
1. Make sure the PC and all other peripheral devices connected to
it has been powered down.
2. Disconnect all power cords and cables.
3. Locate the SODIMM socket on the system board.
4. Insert the module into the socket at an approximately 30 degrees angle. Note that the socket and module are both keyed,
which means the module can be plugged into the socket in only
one way.

5. To seat the module into the socket, apply firm even pressure to
each end of the module until it slips down into the socket. The
contact fingers on the edge of the module will almost completely
disappear inside the socket.

6. Insert the CPU into the socket until it is seated in place. The
CPU will fit in only one orientation and can easily be inserted
without exerting any force. Use a screwdriver to turn the screw
to its lock position.
Important:
Do not force the CPU into the socket. Forcing the CPU into
the socket may bend the pins and damage the CPU.
18
Installing the Fan and Heat Sink
The CPU must be kept cool by using a CPU fan with heat sink.
Without sufficient air circulation across the CPU and heat sink, the
CPU will overheat damaging both the CPU and system board.
Note:
• Use only certified fan and heat sink.
• Your fan and heat sink package usually contains the fan
and heat sink assembly, and an installation guide. If the installation procedure in the installation guide differs from the
one in this section, please follow the installation guide in the
package.
• The fan with heat sink assembly and the system board
used in the following illustrations may not resemble the actual ones. These illustrations are for reference only.

1. On the solder side of the board, match the screw holes of the
retention module base to the mounting holes around the CPU
socket.

2. Apply a thin layer of thermal paste on top of the CPU. Do not
spread the paste all over the surface. When you later place the
heat sink on top, the compound will disperse evenly.
3. While holding the retention module base in position (step 1),
place the fan / heat sink assembly on top of the CPU. The 4
screws around the heat sink must match the screw holes of the
retention module base.
Turn each Phillips head screw half way down first to initially stabilize the heat sink onto the board, then finally tighten each screw.
Important:
Do not turn the first screw all the way down followed by
the next and so on. This is to avoid imbalance which might
cause cracks or fractures to the CPU and/or heat sink assembly.
4. Connect the CPU fan’s cable connector to the CPU fan connector on the system board.

Important:
When you install the CPU fan and heat sink assembly, make
sure the assembly is positioned in such a way that the direction of the airflow blows towards the Northbridge. This is to
ensure optimum thermal condition and system performance.
