Overheatng
Overheatng can serously damage the CPU and manboard. Always make sure the
coolng fans work properly to protect the CPU from overheatng. Be sure to apply an
even layer of thermal paste (or thermal tape) between the CPU and the heatsnk to
enhance heat dsspaton.
Replacng the CPU
When replacng the CPU, always turn o󰘯 the system’s power supply and unplug the
power supply’s power cord to ensure the safety of the CPU.
Overclockng
Ths manboard s desgned to support overclockng. Before attemptng to overclock,
please make sure that all other system components can tolerate overclockng. Any
attempt to operate beyond product spec󰘰catons s not recommend. MSI does not
guarantee the damages or rsks caused by nadequate operaton beyond product
spec󰘰catons.

CPU & Cooler Installaton
When nstallng a CPU, always remember to nstall a CPU cooler. A CPU cooler s
necessary to prevent overheatng and mantan system stablty. Follow the steps below
to ensure correct CPU and CPU cooler nstallaton. Wrong nstallaton can damage both
the CPU and the manboard.
Unhook and lft the loadng lever to
the fully open poston.
1. The loadng plate should
automatcally lft up as the loadng
lever s pushed to the fully open
poston. Do not touch any of the
CPU socket pns.
2.
Lne up the CPU to 󰘰t the CPU
socket. Be sure to hold the CPU by
the base wth the metal contacts
facng downward. The algnment
keys on the CPU wll lne up wth the
edges of the CPU socket to ensure a
correct 󰘰t.

the loadng lever down and lock t
under the retenton tab.
5. Evenly spread a thn layer of
thermal paste (or thermal tape) on
the top of the CPU. Ths wll help n
heat dsspaton and prevent CPU
