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 processors 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.

Memory module installation recommendation
DIMMA1 DIMMB1
DIMMA1
Important
y
Always insert memory modules in the DIMMA1 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 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 processor/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.

* For Ryzen™ 1st and 2nd Generation processors
** For Ryzen™ with Radeon Vega Graphics processors
Important
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
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
cards documentation to check for any necessary additional hardware or software
changes.
SATA1~4: SATA 6Gb/s Connectors
These connectors are SATA 6Gb/s interface ports. Each connector can connect to one
SATA device.

Important
y
Please do not fold the SATA cable at a 90-degree angle. Data loss may result during
transmission otherwise.
y
SATA cables have identical plugs on either sides of the cable. However, it is
recommended that the flat connector be connected to the motherboard for space
saving purposes.
