Important
∙ When changing the processor, the system configuration could be cleared and reset
BIOS to default values, due to the AM4 processor’s architecture.
∙ Always unplug the power cord from the power outlet before installing or removing
the CPU.
∙ When installing a CPU, always remember to install a CPU heatsink. A CPU heatsink
is necessary to prevent overheating and maintain system stability.
∙ Confirm that the CPU heatsink has formed a tight seal with the CPU before booting
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
documentation in the heatsink/ cooler package for more details about installation.
∙ 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.
