CHAPTER 1: INTRODUCTION
1.1 Before You Start
Thank you for choosing our product. Before you start installing the
motherboard, please make sure you follow the instructions below:
Prepare a dry and stable working environment with
sufficient lighting.
Always disconnect the computer from power outlet before
operation.
Before you take the motherboard out from anti-static bag,
ground yourself properly by touching any safely grounded
appliance, or use grounded wrist strap to remove the static
charge.
Avoid touching the components on motherboard or the rear
side of the board unless necessary. Hold the board on the
edge, do not try to bend or flex the board.
Do not leave any unfastened small parts inside the case
after installation. Loose parts will cause short circuits which
may damage the equipment.
Keep the computer from dangerous area, such as heat
source, humid air and water.
The operating temperatures of the computer should be 0 to
45 degrees Celsius.
To avoid injury, be careful of:
Sharp pins on headers and connectors
Rough edges and sharp corners on the chassis
Damage to wires that could cause a short circuit

CHAPTER 2: HARDWARE INSTALLATION
2.1 Install Central Processing Unit (CPU)
Step 1: Locate the CPU socket on the motherboard
Step 2: Pull the socket locking out from the socket and then raise the lever up to
a 90-degree angel.
Step 3: Look for the white triangle on socket, and the gold triangle on CPU
should point towards this white triangle. The CPU will fit only in the
correct orientation.
Note: The CPU fits only in one correct orientation. Do not force the CPU into the socket to
prevent damaging the CPU.

Step 4: Hold the CPU down firmly, and then close the lever to locked the position
2.2 Install a Heatsink
Step 1: Place the heatsink and fan assembly onto the retention frame. Match the
heatsink clip with the socket mounting-lug. Hook the spring clip to the
mounting-lug.
Step 2: On the other side, push the retention clip straight down to lock into the
plastic lug on the retention frame, and then press down the locker until it
stops.
Note1: Do not forget to connect the CPU fan connector.
Note2: For proper installation, please kindly refer to the installation manual of your CPU
heatsink.
