When replacing the CPU, always turn off the system’s power supply and unplug the power supply’s power cord to ensure the safety of the CPU.

Overclocking

This mainboard 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 recommend. MSI does not guarantee the damages or risks caused by inadequate operation beyond product specifications.
