Safety Information
y 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.
y Ensure that all components are securely connected. Loose connections may cause
the computer to not recognize a component or fail to start.
y Hold the motherboard by the edges to avoid touching sensitive components.
y 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.
y Store the motherboard in an electrostatic shielding container or on an anti-static pad
whenever the motherboard is not installed.
y Before turning on the computer, ensure that there are no loose screws or metal
components on the motherboard or anywhere within the computer case.
y Do not boot the computer before installation is completed. This could cause
permanent damage to the components as well as injury to the user.
y If you need help during any installation step, please consult a certified computer
technician.
y Always turn off the power supply and unplug the power cord from the power outlet
before installing or removing any computer component.
y Keep this user guide for future reference.
y Keep this motherboard away from humidity.
y Make sure that your electrical outlet provides the same voltage as is indicated on the
PSU, before connecting the PSU to the electrical outlet.
y Place the power cord such a way that people can not step on it. Do not place anything
over the power cord.
y All cautions and warnings on the motherboard should be noted.

Introduction to the AM4 CPU
The surface of the AM4 CPU has a
yellow triangle to assist in correctly
lining up the CPU for motherboard
placement. The yellow triangle is
the Pin 1 indicator.
Important
y
When changing the processor, the system configuration could be cleared and reset
BIOS to default values, due to the AM4 processor’s architecture.
y
Always unplug the power cord from the power outlet before installing or removing
the CPU.
y
When installing a CPU, always remember to install a CPU heatsink. A CPU heatsink
is necessary to prevent overheating and maintain system stability.
y
Confirm that the CPU heatsink has formed a tight seal with the CPU before booting
your system.
y
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.
y
If you purchased a separate CPU and heatsink/ cooler, Please refer to the
documentation in the heatsink/ cooler package for more details about installation.
y
This motherboard 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
recommended. MSI

Important
y
Always insert memory modules in the DIMMA2 slot first.
y
Due to chipset resource usage, the available capacity of memory will be a little less
than the amount of installed.
y
Based on the processor specification, the Memory DIMM voltage below 1.35V is
suggested to protect the processor.
y
Some memory modules may operate at a lower frequency than the marked value
when overclocking due to the memory frequency operates dependent on its Serial
Presence Detect (SPD). Go to BIOS and find the DRAM Frequency to set the memory
frequency if you want to operate the memory at the marked or at a higher frequency.
y
It is recommended to use a more efficient memory cooling system for full DIMMs
installation or overclocking.
y
The stability and compatibility of installed memory module depend on installed CPU
and devices when overclocking.
y
Due to AM4 CPU/memory controller official specification limitation, the frequency of
memory modules may operate lower than the marked value under the default state.
Please refer www.msi.com for more information on compatible memory.

y
If you install a large and heavy graphics card, you need to use a tool such as MSI
Gaming Series Graphics Card Bolster to support its weight to prevent deformation of
the slot.
y
For a single PCIe x16 expansion card installation with optimum performance, using
the PCI_E1 slot is recommended.
y
When adding or removing expansion cards, always turn off the power supply and
unplug the power supply power cable from the power outlet. Read the expansion
card’s documentation to check for any necessary additional hardware or software
changes.
