CPU Socket
Please install the CPU into the CPU socket as shown below.
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.

Overview of Components
DIMM Slots
Please install the memory module into the DIMM slot as shown below.
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 processor specification, the Memory DIMM voltage below 1.35V is
suggested to protect the processor.
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.

Important
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.
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.

Overview of Components
CPU_FAN1, SYS_FAN1~2: Fan Connectors
Fan connectors can be classified as PWM (Pulse Width Modulation) Mode or DC
Mode. PWM Mode fan connectors provide constant 12V output and adjust fan speed
with speed control signal. DC Mode fan connectors control fan speed by changing
voltage. When you plug a 3-pin (Non-PWM) fan to a fan connector in PWM mode, the
fan speed will always maintain at 100%, which might create a lot of noise. You can
follow the instruction below to adjust the fan connector to PWM or DC Mode.
Switching fan mode and adjusting fan speed
You can switch between PWM mode and DC mode and adjust fan speed in BIOS >
HARDWARE MONITOR.
Select PWM mode or DC mode
Important
Make sure fans are working properly after switching the PWM/ DC mode.
There are gradient points of the fan speed that allow you to
adjust fan speed in relation to CPU temperature.
