 Important
 y
Always unplug the power cord from the power outlet before installing or removing 
the CPU.
 y
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.
 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
Whenever the CPU is not installed, always protect the CPU socket pins by covering 
the socket with the plastic cap.
 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
