Hardware Installation
1-1 Installation Precautions
The motherboard contains numerous delicate electronic circuits and components which can
become damaged as a result of electrostatic discharge (ESD). Prior to installation, carefully read
the user's manual and follow these procedures:
• Prior to installation, do not remove or break motherboard S/N (Serial Number) sticker or
warranty sticker provided by your dealer. These stickers are required for warranty validation.
• Always remove the AC power by unplugging the power cord from the power outlet before
installing or removing the motherboard or other hardware components.
• When connecting hardware components to the internal connectors on the motherboard,
make sure they are connected tightly and securely.
• When handling the motherboard, avoid touching any metal leads or connectors.
• It is best to wear an electrostatic discharge (ESD) wrist strap when handling electronic com-
ponents such as a motherboard, CPU or memory. If you do not have an ESD wrist strap,
keep your hands dry and rst touch a metal object to eliminate static electricity.
• Prior to installing the motherboard, please have it on top of an antistatic pad or within an
electrostatic shielding container.
• Before unplugging the power supply cable from the motherboard, make sure the power sup-
ply has been turned off.
• Before turning on the power, make sure the power supply voltage has been set according to
the local voltage standard.
• Before using the product, please verify that all cables and power connectors of your hard-
ware components are connected.
• To prevent damage to the motherboard, do not allow screws to come in contact with the
motherboard circuit or its components.
• Make sure there are no leftover screws or metal components placed on the motherboard or
within the computer casing.
• Do not place the computer system on an uneven surface
.
• Do not place the computer system in a high-temperature environment.
• Turning on the computer power during the installation process can lead to damage to sys-
tem components as well as physical harm to the user.
• If you are uncertain about any installation steps or have a problem related to the use of the
product, please consult a certied computer technician.

1-3-1 DualChannelMemoryConguration
This motherboard provides two DDR3 memory sockets and supports Dual Channel Technology. After the
memory is installed, the BIOS will automatically detect the specications and capacity of the memory. En-
abling Dual Channel memory mode will double the original memory bandwidth.
1-3 InstallingtheMemory
Read the following guidelines before you begin to install the memory:
•Make sure that the motherboard supports the memory. It is recommended that memory of the
same capacity, brand, speed, and chips be used.
•Always turn off the computer and unplug the power cord from the power outlet before installing
the memory to prevent hardware damage.
•Memory modules have a foolproof design. A memory module can be installed in only one
direction. If you are unable to insert the memory, switch the direction.
NOTE!
•DIMM must be populated in order starting from SO_DIMM2 socket. For Dual-channel operation,
DIMMs must be installed in matched pairs.

1-4 BackPanelConnectors
DCPowerJack
Connect the DC power to this port.
RJ-45 LAN Port
The Gigabit Ethernet LAN port provides Internet connection at up to 1 Gbps data rate. The following
describes the states of the LAN port LEDs.
HDMI Port
The HDMI (High-Denition Multimedia Interface) provides an all-digital audio/video interface to
transmit the uncompressed audio/video signals and is HDCP compliant. Connect the HDMI
audio/video device to this port. The HDMI Technology can support a maximum resolution of
1920x1080p but the actual resolutions supported depend on the monitor being used.
USB2.0Port
The USB port supports the USB 2.0 specication. Use this port for USB devices such as a USB key-
board/mouse, USB printer, USB ash drive and etc.
LineOutJack(Green)
The default line out jack. Use this audio jack for a headphone or 2-channel speaker. This jack can be
used to connect front speakers in a 4/5.1/7.1-channel audio conguration.
LineInJack(Blue)
The default line in jack. Use this audio jack for line in devices such as an optical drive, walkman, etc.
• When After installing the HDMI device, make sure the default device for sound playback is the
HDMI device. (The item name may differ by operating system. Refer the gures below
for details.), and enter BIOS Setup, then set Onboard VGA output connect to D-SUB/
HDMI under Advanced BIOS Features..
• Please note the HDMI audio output only supports AC3, DTS and 2-channel-LPCM
formats. (AC3 and DTS require the use of an external decoder for decoding.)
• When removing the cable connected to a back panel connector, rst remove the cable from your
device and then remove it from the motherboard.
• When removing the cable, pull it straight out from the connector. Do not rock it side to side to
prevent an electrical short inside the cable connector.

6) F_AUDIO(FrontPanelAudioHeader)
The front panel audio header supports Intel High Denition audio (HD) and AC'97 audio. You may connect
your chassis front panel audio module to this header. Make sure the wire assignments of the module con-
nector match the pin assignments of the motherboard header. Incorrect connection between the module
connector and the motherboard header will make the device unable to work or even damage it.
•The front panel audio header supports HD audio by default.
•Audio signals will be present on both of the front and back panel audio connections
simultaneously.
•Some chassis provide a front panel audio module that has separated connectors on each wire
instead of a single plug. For information about connecting the front panel audio module that has
different wire assignments, please contact the chassis manufacturer.

11/12)CPU_FAN/SYS_FAN(CPUFan/SystemFanHeaders)
The motherboard has a 4-pin CPU fan header (CPU_FAN) and a 4-pin System fan header (SYS_FAN)
header. Most fan headers possess a foolproof insertion design. When connecting a fan cable, be sure
to connect it in the correct orientation (the black connector wire is the ground wire). The motherboard
supports CPU fan speed control, which requires the use of a CPU fan with fan speed control design. For
optimum heat dissipation, it is recommended that a system fan be installed inside the chassis.
•Be sure to connect fan cables to the fan headers to prevent your CPU and system from
overheating. Overheating may result in damage to the CPU or the system may hang.
• These fan headers are not conguration jumper blocks. Do not place a jumper cap on the headers.
