Safety Precautions

The following precautions should be observed while handling the system:

- Place the system on a flat and stable surface.

- Do not place the system in environments subject to mist, smoke, vibration, excessive dust, salty or greasy air, or other corrosive gases and fumes.

- Do not drop or jolt the system.

- Do not use another power adapter other than the one enclosed with the system.

- Disconnect the power cord before performing any installation procedures on the system.

• Do not perform any maintenance with wet hands.

- Prevent foreign substances, such as water, other liquids or chemicals, from entering the system while performing installation procedures on the system.

- Use a grounded wrist strap before handling system components such as CPU, Memory, HDD, expansion cards, etc.

- Place system components on a grounded antistatic pad or on the bed that came with the components whenever the components are separated from the system.

The system photos are provided for demonstration of system assembly only. The internal view of your system may vary depending on the model you purchased.

System Setup

Before removing or installing any components, make sure the system is not turned on or connected to the power.

CPU

When installing the CPU, make sure that you install cooler to prevent overheating. If you do not have the CPU cooler, consult your dealer before turning on the computer.

For the instruction of installing CPU cooler, please see Air Cooler Module (Optional) or Water Cooler Module (Optional) chapter.

Important

While replacing the CPU, always turn off the power supply or unplug the power supply's power cord from the grounded outlet first to ensure the safety of CPU.

Overheating will seriously damage the CPU and system. Always make sure the cooling fan can work properly to protect the CPU from overheating. Make sure to apply an even layer of thermal paste (or thermal tape) between the CPU and the heatsink to enhance heat dissipation.

Confirm if your CPU cooler is firmly installed before turning on your system.

Do not touch the CPU socket pins to avoid damage.

Whenever CPU is not installed, always protect your CPU socket pins with the plastic cap covered.

Please refer to the documentation in the CPU cooler package for more details about the CPU cooler installation.

Read the CPU status in BIOS.

Memory

1. Unlock the DIMM slot by flipping open its side clips.
2. Vertically insert the DIMM into the DIMM slot. The DIMM has an off-center notch at the bottom that will only allow it to fit one way into the DIMM slot.
3. Push the DIMM deeply into the DIMM slot. The side clips of the slot will automatically close when the DIMM is properly seated and an audible click should be heard.
4. Manually check if the DIMM has been locked in place by the DIMM slot's side clips.
