Hardware Installation Process
Chapter 2 Hardware Installation Process
2.1.Installing Processor and CPU Haet Sink
Before installing the processor and cooling fan, adhere to the following
cautions:
1. The processor will overheat without the heatsink and/or fan, resulting in permanent
irreparable damage.
2. Never force the processor into the socket.
3. Apply thermal grease on the processor before placing cooling fan.
4. Please make sure the CPU type is supported by the motherboard.
5. If you do not match the CPU socket Pin 1 and CPU cut edge well, it will cause
improper installation. Please change the insert orientation.
2.1.1. Installing CPU
Step 1 Raise the metal locking lever on the socket.
Step 2 Remove the plastic covering on the CPU socket.
Step 3 Insert the CPU with the correct orientation. The CPU only fits in one orientation.
Step 4 Once the CPU is properly placed, please replace the metal cover and push the metal
lever back into locked position.

Hardware Installation Process
2.2.Installing memory modules
Before installing the memory modules, please comply with the following conditions:
1. Please make sure that the memory is supported by the motherboard. It is
recommended to use the memory with similar capacity, specifications and brand.
2. Before installing or removing memory modules, please make sure that the computer
power is switched off to prevent hardware damage.
3. Memory modules have a foolproof insertion design. A memory module can be installed
in only one direction. If you are unable to insert the module, please switch the direction.
The motherboard supports DDR3 memory modules, whereby BIOS will automatically detect memory
capacity and specifications. Memory modules are designed so that they can be inserted only in one
direction. The memory capacity used can differ with each slot.

Hardware Installation Process
Installation Steps:
Step 1. Insert the DIMM memory module vertically into the DIMM slot, and push it down.
Step 2. Close the plastic clip at both edges of the DIMM slots to lock the DIMM module.
NOTE! DIMM must be populated in order starting from DIMMA1/D1 socket. For dual-channel
operation, DIMMs must be installed in matched pairs.
Step 3. Reverse the installation steps when you wish to remove the DIMM module.

With the use of the power connector, the power supply can supply enough stable power to all the
components on the motherboard. Before connecting the power connector, please make sure that
all components and devices are properly installed. Align the power connector with its proper
location on the motherboard and connect tightly.
The ATX_12V power connector mainly supplies power to the CPU. If the ATX_12V
power connector is not connected, the system will not start.
Caution! Please use a power supply that is able to support the system voltage
requirements. It is recommended that a power supply that can withstand high power
consumption be used (350W or greater). If a power supply is used that does not provide
the required power, the result can lead to an unstable system or a system that is unable
to start. If you use a power supply that provides a 24-pin A TX power connector, please
remove the small cover on the power connector on the motherboard before plugging in
the power cord; otherwise, please do not remove it.
