Important
 Always unplug the power cord from the power outlet before installing or removing
the CPU.
 Please retain the CPU protective cap after installing the processor. MSI will deal
with Return Merchandise Authorization (RMA) requests if only the motherboard
comes with the protective cap on the CPU socket.
 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.
 Whenever the CPU is not installed, always protect the CPU socket pins by covering
the socket with the plastic cap.
 If you purchased a separate CPU and heatsink/ cooler, Please refer to the
documentation in the heatsink/ cooler package for more details about installation.
CPU Socket
Please install the CPU into the CPU socket as shown below.
