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.

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.

Hardware Installation
The system board supports the following memory interface.
Single Channel (SC)
Data will be accessed in chunks of 64 bits (8B) from the memory
channels.
Dual Channel (DC)
Data will be accessed in chunks of 128 bits from the memory channels. Dual channel provides better system performance because it
doubles the data transfer rate.

•DIMMs are on the same channel.
•DIMMs in a channel can be identical or
completely different. However, we highly recommend using identical DIMMs.
•Not all slots need to be populated.
•DIMMs of the same memory configura-
tion are on different channels.

that the CPU is completely secured in the
socket.
Installing the Fan and Heat Sink
Cover
Lever
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.
•The 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.
1.Before you install the fan / heat sink, you must apply a thermal
paste onto the top of the CPU. The thermal paste is usually
supplied when you purchase the CPU or fan heat sink assembly.
Do not spread the paste all over the surface. When you later
place the heat sink on top of the CPU, the compound will disperse evenly.
22
Do not apply the paste if the fan / heat sink already has a patch
of thermal paste on its underside. Peel the strip that covers the
paste before you place the fan / heat sink on top of the CPU.

2.Place the heat sink on
top of the CPU. The 4
studs around the heat
sink which are used to
secure the heat sink
onto the system board
must match the 4
mounting holes around
the socket.
Position each stud so
that the groove faces
the heat sink then push
it down firmly until it
clicks into place.
