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.
A780L3C
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.

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.

2.4 Installing System Memory
A. DDR3 Memory Modules
Step 1: Unlock a DIMM slot by pressing the retaining clips outward. Align a DIMM
on the slot such that the notch on the DIMM matches the break on the slot.
Step 2: Insert the DIMM vertically and firmly into the slot until the retaining chip snap
back in place and the DIMM is properly seated.
Note: If the DIMM does not go in smoothly, do not force it. Pull it all the way out and try again.
