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

2.1 Installing Memory Module
DIMM1/ DIMM2: DDR4 Memory Module Slot (260pins SO-DIMM)
Note
»
»If the DIMM does not go in smoothly, do not force it. Pull it all the way out and try again.
Insert memory module into SO-DIMM socket at backside of motherboard.
1. Hold the SO-DIMM with its notch aligned with the memory socket of the board and insert it at a
30-degree angle into the socket.
2. Press down on the SO-DIMM so that the tabs of the socket lock on both sides of the module.
»
»To avoid generang stac electricity and damaging the SO-DIMM, ground yourself by touching a grounded metal
surface or use a ground strap before you touch the SO-DIMM.
1. Align a DIMM on the slot such that the notch on the DIMM matches the break on the Slot.
2. Insert the DIMM rmly into the slot unl the retaining chip snap back in place and the DIMM is properly
seated.
