Safety Instructions

To reduce the risk of re, electric shock, and injury, always follow basic safety precations.

Remember to remove power from your computer by disconnecting the AC main
source before removing or installing any equipment from/to the computer chassis.

Preparing the Motherboard

The motherboard shipped in the box does not contain a CPU and memory. You need

to purchase these to complete this installation.

AMD A75ITX series motherboard

Installing the CPU

Be very careful when handling the CPU. Make sure not to bend or break any pins on
the back. Hold the processor only by the edges and do not touch the bottom of the
processor.
Use the following procedure to install the CPU onto the motherboard.

1. Please turn off the power and unplug the power
cord before installing the CPU. Pull the lever up and
away from the socket until it is at a 90 degree angle

to the motherboard.

2. Look for the gold arrow on the CPU. The gold arrow
should point away from the lever pivot. The CPU can
only sit properly in the socket in the correct orientation.

3. If the CPU is correctly seated, the pins should be
completely embedded in the socket and can not be
seen (Please note that any deviation from the correct
installation procedures may cause permanent damage
to your motherboard).

4. Press the CPU down rmly into the socket and

close the lever. As the CPU is likely to move while
the lever is being closed, always close the lever with

your ngers pressing tightly on top of the CPU to

make sure the CPU is properly and completely seated
in the socket.

5. When you are installing the CPU, make sure the
CPU has a heat sink and a cooling fan attached on
the top to prevent overheating. If you do not have the
heat sink and cooling fan, contact your dealer to
purchase and install them before turning on the

computer.

Installing the CPU Fan

There are many different fan types that can be used with this motherboard. Follow the
instruction that came with your fan assembly. Be sure that the fan orientation is correct
for your chassis type and your fan assembly.

Installing Memory Modules

This motherboard accommodates two memory modules. It can support two 240-pin
DDR3 1866/1600/1333/1066. The total memory capacity is 8 GB. You must install at
least one module in any of the two slots. Refer to the following recommendations to
install the memory modules.

Note that a memory module has a notch, so it can only t in one direction. Refer to the following

procedure to install memory modules into the slots on the motherboard.

1. Unlock a DIMM slot by pressing the module clips outward.

2. Align the memory module to the DIMM slot, and insert the module vertically into the DIMM

slot. The plastic clips at both sides of the DIMM slot automatically lock the DIMM into the
connector.

AMD A75ITX series motherboard

Installing the Motherboard

The sequence of installing the motherboard into the chassis depends on the chassis

you are using and if you are replacing an existing motherboard or working with an

empty chassis. Determine if it would be easier to make all the connections prior to this
step or to secure the motherboard and then make all the connections. It is normally

easier to secure the motherboard rst.

Use the following procedure to install the I/O shield and secure the motherboard into
the chassis.

Note: Be sure that the CPU fan assembly has enough clearance for the
chassis covers to lock into place and for the expansion cards. Also
make sure the CPU Fan assembly is aligned with the vents on the
covers.

Installing the I/O Shield

The motherboard kit comes with an I/O shield that is used to block radio frequency

transmissions, protects internal components from dust and foreign objects, and
promotes correct airow within the chassis.

Before installing the motherboard, install the I/O shield from the inside of the chassis.

Press the I/O shield into place and make sure it ts securely. If the I/O shield does not
t into the chassis, you would need to obtain the proper size from the chassis supplier.

Securing the Motherboard into the Chassis

Most computer chassis have a base with mounting studs or spacers to allow the
motherboard to be secured to the chassis and help to prevent short circuits. If there are
studs that do not align with a mounting hole on the motherboard, it is recommended
that you remove that stud to prevent the possibility of a short circuit. In most cases, it
is recommended to secure the motherboard with spacers.

1. Carefully place the motherboard onto the studs/spacers located inside the
chassis.

2. Align the mounting holes with the studs/spacers.

3. Align the connectors to the I/O shield.

4. Ensure that the fan assembly is aligned with the chassis vents according to the fan
assembly instruction.

5. Secure the motherboard with screws.

The audio connector supports HD audio standard and provides two kinds of audio
output choices: the Front Audio, the Rear Audio. The front Audio supports re-tasking
function.

Note:

In order to utilize the front audio header,

your chassis must have front audio

connector. Also please make sure the

pin assignment on the cable is the same

as the pin assignment on the mainboard

header. To nd out if the chassis you are

buying supports a front audio connector,

please contract your dealer.

Front Panel Header

The front panel header on this motherboard is one connector used to connect the
following four cables:
q PWR LED

Attach the front panel power LED cable to these two pins of the connector. The
Power LED indicates the system’s status.

q PWR SW

Attach the power button cable from the case to these two pins. Pressing the
power button on the front panel turns the system on and off rather than using the
power supply button.

q HDD LED

Attach the hard disk drive indicator LED cable to these two pins. The HDD indicator
LED indicates the activity status of the hard disks.

q RST SW

Attach the Reset switch cable from the front panel of the case to these two pins.
The system restarts when the RESET switch is pressed.

Note: Some chassis do not have all four cables. Be sure to match the name on
the connectors to the corresponding pins.
