• 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 a Micro ATX form factor of 244 x 200 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.
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.

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 surfacemount 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.
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 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.
This motherboard has an LGA1156 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.
