1-3 Installation of the CPU and Heatsink
Before installing the CPU, please comply with the following conditions:
English
1. Please make sure that the motherboard supports the CPU.
2. Please take note of the one indented corner of the CPU. If you install the CPU in the wrong
direction, the CPU will not insert properly. If this occurs, please change the insert direction
of the CPU.

overheating and permanent damage of the CPU may occur.
5. Please set the CPU host frequency in accordance with the processor specifications. It is not
recommended that the system bus frequency be set beyond hardware specifications since it
does not meet the required standards for the peripherals. If you wish to set the frequency
beyond the proper specifications, please do so according to your hardware specifications
including the CPU, graphics card, memory, hard drive, etc.

1-4 Installation of Memory
Before installing the memory modules, please comply with the following conditions:
1. Please make sure that the memory used is supported by the motherboard. It is
English
recommended that memory of similar capacity, specifications and brand be used.
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 DDR 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.

1/2) ATX_12V / ATX (Power Connector)
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
English
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 handle the system voltage requirements. It is
recommended that a power supply that can withstand high power consumption be used (300W
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.
