CHAPTER 1: INTRODUCTION
1.1BEFORE 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.

CHAPTER 2: HARDWARE INSTALLATION
2.1INSTALLING CENTRAL PROCESSING UNIT (CPU)
Step 1: Remove the socket protection cap.
Step 2: Pull the lever toward direction A from the socket and then raise the lever up to a 90-degree angle.
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.
5
Motherboard Manual 
Step 4: Hold the CPU down firmly, and then close the lever toward direct B to complete the installation.
Step 5: Put the CPU Fan on the CPU and buckle it. Connect the CPU FAN power cable to the JCFAN1. This completes the installation.
Note: Please update the BIOS to the latest version while using AM2+ CPUs. Due to the latest CPU transition, you may encounter the situation that the new system failed to boot while using new AM2+ CPUs. In this case, please install one standard AM2 CPU to boot your system, and update the latest BIOS from our website for AM2+ CPUs support.
