Installing the Motherboard
Safety Precautions
• Follow these safety precautions when installing the motherboard
• Wear a grounding strap attached to a grounded device to avoid damage from static electricity
• Discharge static electricity by touching the metal case of a safely
grounded object before working on the motherboard
• Leave components in the static-proof bags they came in
• Hold all circuit boards by the edges. Do not bend circuit boards
Choosing a Computer Case
There are many types of computer cases on the market. The motherboard complies
with the specifications for the Micro ATX system case. Some features on the
motherboard are implemented by cabling connectors on the motherboard to indicators and switches on the system case. Make sure that your case supports all the
features required. Make sure that your case has sufficient power and space for all
drives that you intend to install.
Most cases have a choice of I/O templates in the rear panel. Make sure that the I/O
template in the case matches the I/O ports installed on the rear edge of the
motherboard.
This motherboard carries an MATX form factor of 244 X 220 mm. Choose a case
that accommodates this form factor.
Installing the Motherboard in a Case
Refer to the following illustration and instructions for installing the motherboard in
a case.
Most system cases have mounting brackets installed in the case, which correspond
the holes in the motherboard. Place the motherboard over the mounting brackets
and secure the motherboard onto the mounting brackets with screws.
Ensure that your case has an I/O template that supports the I/O ports and expansion
slots on your motherboard.
10
Installing the Motherboard
Do not over-tighten the screws as this can stress the motherboard.
Checking Jumper Settings
This section explains how to set jumpers for correct configuration of the motherboard.
Setting Jumpers
Use the motherboard jumpers to set system configuration options. Jumpers with
more than one pin are numbered. When setting the jumpers, ensure that the jumper
caps are placed on the correct pins.
The illustrations show a 2-pin jumper. When
the jumper cap is placed on both pins, the
jumper is SHORT. If you remove the jumper
cap, or place the jumper cap on just one pin,
the jumper is OPEN.
This illustration shows a 3-pin jumper. Pins
1 and 2 are SHORT.
SHORT OPEN

Installing the Motherboard
Installing Hardware
Installing the Processor
Caution: When installing a CPU heatsink and cooling fan make sure that
you DO NOT scratch the motherboard or any of the surface-mount resistors with the clip of the cooling fan. If the clip of the cooling fan scrapes
across the motherboard, you may cause serious damage to the motherboard
or its components.
On most motherboards, there are small surface-mount resistors near the
processor socket, which may be damaged if the cooling fan is carelessly
installed.
Avoid using cooling fans with sharp edges on the fan casing and the clips.
Also, install the cooling fan in a well-lit work area so that you can clearly
see the motherboard and processor socket.
This motherboard has a socket FM1 processor socket. When choosing a processor,
consider the performance requirements of the system. Performance is based on the
processor design, the clock speed and system bus frequency of the processor, and the
quantity of internal cache memory and external cache memory.
Before installing the Processor
This motherboard automatically determines the CPU clock frequency and system
bus frequency for the processor. You may be able to change these settings by making
changes to jumpers on the motherboard, or changing the settings in the system Setup
Utility. We strongly recommend that you do not over-clock processors or other
components to run faster than their rated speed.
Warning:
1. Over-clocking components can adversely affect the reliability of the
system and introduce errors into your system. Over-clocking can permanently damage the motherboard by generating excess heat in components
that are run beyond the rated limits.
2. Always remove the AC power by unplugging the power cord from the
power outlet before installing or removing the motherboard or other hardware components.
13
Installing the Motherboard
CPU Installation Procedure
The following illustration shows CPU installation components.
To achieve better airflow rates and heat dissipation, we suggest that you
use a high quality fan with 4800 rpm at least. CPU fan and heatsink
installation procedures may vary with the type of CPU fan/heatsink supplied. The form and size of fan/heatsink may also vary.
Installing Memory Modules
This motherboard accommodates four memory modules. It can support four 240-pin
DDR3 1866/1600/1333. The total memory capacity is 32 GB.
