SafetyPrecautions
• Follow these safety precautions when installing the motherboard
• Wear a grounding strap attached to a grounded device to avoid dam-
age 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
ChoosingaComputer 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 indica-
tors and switches on the system case. Make sure that your case supports all the
features required.
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 244 mm. Choose a case
that accommodates this form factor.
InstallingtheMotherboard ina 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.

CheckingJumperSettings
This section explains how to set jumpers for correct configuration of the motherboard.
SettingJumpers
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
Do not over-tighten the screws as this can stress the motherboard.

Checking Jumper Settings
The following illustration shows the location of the motherboard jumpers. Pin 1 is
labeled.

To avoid the system instability after clearing CMOS, we recommend users
to enter the main BIOS setting page to “Load Default Settings” and then
“Save and Exit Setup”.

InstallingHardware
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 resis-
tors 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.
This motherboard has an LGA1155 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.
Warning:
1. Over-clocking components can adversely affect the reliability of the
system and introduce errors into your system. Over-clocking can perma-
nently 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.
Fail-Safe Procedures for Over-clocking
When end-users encounter failure after attempting over-clocking, please take the
following steps to recover from it.
1. Shut down the computer.
2. Press and hold the “Page Up Key (PgUp)” of the keyboard, and then boot the
PC up.
3. Two seconds after the PC boots up, release the “Page Up Key (PgUp)”.
4. The BIOS returns to the default setting by itself.

CPU Installation Procedure
The following illustration shows CPU installation components.
A. Press the hook of lever down with your thumb and pull it to the right side
to release it from retention tab.
B. Lift the tail of the load lever and rotate the load plate to fully open
position.
C. Grasp the edge of the package substrate. Make sure pin 1 indicator is on
your bottom-left side. Aim at the socket and place the package carefully into
the socket by purely vertical motion.
D. Rotate the load plate onto the package IHS (Intergraded Heat Spreader).
Engage the load lever while pressing down lightly onto the load plate. Secure
the load lever with the hook under retention tab. Then the cover will flick
automatically.
Please save and replace the cover onto the CPU socket if processor is
removed.

14
InstallingtheMotherboard
E. Aplly some thermal grease onto the contacted area between the heatsink
and the CPU, and make it to be a thin layer.
F. Fasten the cooling fan supporting base onto the CPU socket on the
motherboard. And make sure the CPU fan is plugged to the CPU fan connector.
G. Connect the CPU cooler power connector to the CPU_FAN connector.
1. To achieve better airflow rates and heat dissipation, we suggest that you
use a high quality fan with 3800 rpm at least. CPU fan and heatsink instal-
lation procedures may vary with the type of CPU fan/heatsink supplied. The
form and size of fan/heatsink may also vary.
2. DO NOT remove the CPU cap from the socket before installing a CPU.
3. Return Material Authorization (RMA) requests will be accepted only if the
motherboard comes with the cap on the LGA1155 socket.

Installing Memory Modules
This motherboard accommodates four memory modules. It can support four 240-pin
DDR3 1600/1333/1066. The total memory capacity is 16 GB.
You must install at least one module in any of the four slots.
DDR3 SDRAM memory module table
Installation Procedure
Refer to the following to install the memory modules.
1 This motherboard supports unbuffered DDR3 SDRAM .
2 Push the latches on each side of the DIMM slot down.
3 Align the memory module with the slot. The DIMM slots are keyed with
notches and the DIMMs are keyed with cutouts so that they can only be
installed correctly.
4 Check that the cutouts on the DIMM module edge connector match the
notches in the DIMM slot.
5 Install the DIMM module into the slot and press it firmly down until it
seats correctly. The slot latches are levered upwards and latch on to
the edges of the DIMM.
6 Installany remaining DIMM modules.
Do not remove any memory module from its antistatic packaging until
you are ready to install it on the motherboard. Handle the modules only
by their edges. Do not touch the components or metal parts. Always wear
a grounding strap when you handle the modules.

Installing Add-on Cards
The slots on this motherboard are designed to hold expansion cards and connect them
to the system bus. Expansion slots are a means of adding or enhancing the
motherboard’s features and capabilities. With these efficient facilities, you can in-
crease the motherboard’s capabilities by adding hardware that performs tasks that are
not part of the basic system.
Before installing an add-on card, check the documentation for
the card carefully. If the card is not Plug and Play, you may
have to manually configure the card before installation.
Expansion Slots
PCIE16X Slot The PCI Express x16 slot is used to install an external PCI
Express graphics card that is fully compliant to the PCI Express
Base Specification revision 3.0.
PCIE1X_1 Slot The PCI Express x1 slot is fully compliant to the PCI Express
Base Specification revision 2.0.
PCI1~2 Slots This motherboard is equipped with two standard PCI slots. PCI
stands for Peripheral Component Interconnect and is a bus
standard for expansion cards, which for the most part, is a
supplement of the older ISA bus standard. The PCI slot on this
board is PCI v2.3 compliant.
