Ensure that all components are securely connected. Loose connections may cause
the computer to not recognize a component or fail to start.
Hold the motherboard by the edges to avoid touching sensitive components.
It is recommended to wear an electrostatic discharge (ESD) wrist strap when
handling the motherboard to prevent electrostatic damage. If an ESD wrist strap is
not available, discharge yourself of static electricity by touching another metal object
before handling the motherboard.
Store the motherboard in an electrostatic shielding container or on an anti-static
pad whenever the motherboard is not installed.
Before turning on the computer, ensure that there are no loose screws or metal
components on the motherboard or anywhere within the computer case.

permanent damage to the components as well as injury to the user.
If you need help during any installation step, please consult a certified computer
technician.
Always turn off the power supply and unplug the power cord from the power outlet
before installing or removing any computer component.
Keep this user guide for future reference.
Keep this motherboard away from humidity.
Make sure that your electrical outlet provides the same voltage as is indicated on
the PSU, before connecting the PSU to the electrical outlet.
Place the power cord such a way that people can not step on it. Do not place
anything over the power cord.

Always unplug the power cord from the power outlet before installing or removing
the CPU.
Please retain the CPU protective cap after installing the processor. MSI will deal
with Return Merchandise Authorization (RMA) requests if only the motherboard
comes with the protective cap on the CPU socket.
When installing a CPU, always remember to install a CPU heatsink. A CPU heatsink
is necessary to prevent overheating and maintain system stability.
your system.
Overheating can seriously damage the CPU and motherboard. 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.
If you purchased a separate CPU and heatsink/ cooler, Please refer to the docu-
mentation in the heatsink/ cooler package for more details about installation.

Due to chipset resource usage, the available capacity of memory will be a little less
than the amount of installed.
Please note that the maximum capacity of addressable memory is 4GB or less
for 32-bit Windows OS due to the memory address limitation. Therefore, we recom-
mended that you to install 64-bit Windows OS if you want to install more than 4GB
memory on the motherboard.
