Overview of Components Overview of Components
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.
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®does not guarantee the damages or risks caused by
inadequate operation beyond product specifications.

8Overview of Components
DIMM Slots
Please install the memory module into the DIMM slot as shown below.
Important
y Due to chipset resource usage, the available capacity of memory will be a little less
than the amount of installed.
y 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
recommended that you to install 64-bit Windows OS if you want to install more than
4GB memory on the motherboard.
PCI_E1~3: PCIe Expansion Slots
PCI_E1: PCIe 3.0 x1 slot
PCI_E2: PCIe 3.0 x16 slot
PCI_E3: PCIe 3.0 x1 slot
Important
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.

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.
