1�1 Before You Start
Thank you for choosing our product. Before you start installing the motherboard, please make
sure you follow the instrucons below:
• Prepare a dry and stable working environment with sucient lighng.
• Always disconnect the computer from power outlet before operaon.
• Before you take the motherboard out from an-stac bag, ground yourself properly
by touching any safely grounded appliance, or use grounded wrist strap to remove the
stac 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 ex the board.
• Do not leave any unfastened small parts inside the case aer installaon. 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 operang 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
1.2 Package Checklist
• Serial ATA Cable x4
• Rear I/O Panel for ATX Case x1

Note
»
»Remove pin cap before installaon, and make good preservaon for future use. When the CPU is
removed, cover the pin cap on the empty socket to ensure pin legs won’t be damaged.
»
»The motherboard might equip with two dierent types of pin cap. Please refer below instrucon to
remove the pin cap.
Step 2: Open ILM Lever and then load plate using nger tab.
Step 3: Align and seat processor package on socket.

10 | Chapter 2: Hardware installaon
Step 4: Close the load plate.
Step 5: Remove and save cover.
Step 6: Close ILM Lever and latch
Note
»
»Ensure that you install the correct CPU designed for LGA1700 socket.
»
»The CPU ts only in one correct orientaon. Do not force the CPU into the socket to prevent
damaging the CPU.

2.2 Install a Heatsink
Step 1: Place the CPU fan assembly on top of the installed CPU and make sure that the four
fasteners match the motherboard holes. Orient the assembly and make the fan cable is closest
to the CPU fan connector.
Step 2: Press down two fasteners at one me in a diagonal sequence to secure the CPU fan
assembly in place. As each fastener locks into posion a click should be heard.
Note
»
»Apply the thermal interface material on the CPU before heatsink installaon, if necessary.
»
»Do not forget to connect the CPU fan connector.
»
»For proper installaon, please kindly refer to the installaon manual of your CPU heatsink.
