Assembly Precautions

■ The components included in this package are prone to damage from electrostatic
discharge (ESD). Please adhere to the following instructions to ensure successful
computer assembly.
■ Always turn off the power supply and unplug the power cord from the power outlet
before installing or removing any computer component.	1Chapter
■ Ensure that all components are securely connected. Loose connections may cause
discharge yourself of static electricity by touching another metal object before han-
the computer to not recognize a component or fail to start.
■ Hold the mainboard by the edges to avoid touching sensitive components.
■ It is recommended to wear an electrostatic discharge (ESD) wrist strap when handling
the mainboard to prevent electrostatic damage. If an ESD wrist strap is not available,
dling the mainboard.
■ Store the mainboard in an electrostatic shielding container or on an antistatic pad
whenever the mainboard is not installed.
■ Before turning on the computer, ensure that there are no loose screws or metal com-
ponents on the mainboard or anywhere within the computer case.
■ Do not use the computer in a high-temperature environment.
■ Do not boot the computer before installation is completed. This could cause perma-
nent damage to the components as well as injury to the user.
■ If you need help during any installation step, please consult a certified computer tech-
nician.

Overheating

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

Replacing the CPU

When replacing the CPU, always turn off the system’s power supply and unplug the power supply’s power cord to ensure the safety of the CPU.

Overclocking

This mainboard is designed to support overclocking. Before attempting to overclock, please make sure that all other system components can tolerate overclocking. Any attempt to operate beyond product specifications is not recommend. MSI does not guarantee the damages or risks caused by inadequate operation beyond product specifications.
