Overheating
Overheating can seriously damage the CPU and mainboard. 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.
Replacing the CPU
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.
En-8
CPU & Cooler Installation
When installing a CPU, always remember to install a CPU cooler. A CPU cooler is
necessary to prevent overheating and maintain system stability. Follow the steps below
to ensure correct CPU and CPU cooler installation. Wrong installation can damage both
the CPU and the mainboard.

Mounting Screw Holes
When installing the mainboard, first install the necessary mounting stands required for
a mainboard on the mounting plate in your computer case. If there is an I/O back plate
that came with the computer case, please replace it with the I/O backplate that came
with the mainboard package. The I/O backplate should snap easily into the computer
case without the need for any screws. Align the mounting plate’s mounting stands with
the screw holes on the mainboard and secure the mainboard with the screws provided
with your computer case. The locations of the screw holes on the mainboard are shown
below. For more information, please refer to the manual that came with the computer
case.

The I/O ports should be facing toward
the rear of the computer case. They
should line up with the holes on the
I/O backplate.
Important
• Install the mainboard on a flat surface free from unnecessary debris.
• To prevent damage to the mainboard, any contact between the mainboard circuitry
and the computer case, except for the mounting stands, is prohibited.
• Please make sure there are no loose metal components on the mainboard or within
the computer case that may cause a short circuit of the mainboard.

Make sure that all the power cables are securely connected to a proper ATX power
supply to ensure stable operation of the mainboard.
En-13
English
This connector allows you to connect an ATX 24-pin power supply. To connect the ATX
24-pin power supply, align the power supply cable with the connector and firmly press
the cable into the connector. If done correctly, the clip on the power cable should be
hooked on the mainboard’s power connector.

• DDR3 memory modules are not interchangeable with DDR2, and the DDR3 standard
is not backward compatible. Always install DDR3 memory modules in DDR3 DIMM
slots.
• To ensure system stability, memory modules must be of the same type and density
in Dual-Channel mode.
• Due to chipset resource usage, the system will only detect up to 31+ GB of memory
(not full 32 GB) when all DIMM slots have 8GB memory modules installed.
En-14
Installing Memory Modules
1. Unlock the DIMM slot by pushing the mounting clips to the side. Vertically insert the
memory module into the DIMM slot. The memory module has an off-center notch on
the bottom that will only allow it to fit one way into the DIMM slot.

• Many computer cases also require that large SATA devices, such as HDDs, SSDs,
and optical drives, be screwed down into the case. Refer to the manual that came
with your computer case or your SATA device for further installation instructions.
• Please do not fold the SATA cable at a 90-degree angle. Data loss may result during
transmission otherwise.

recommended CPU cooling fans.
• The CPUFAN connector supports Smart Fan Control with linear mode. The Control
Center II utility can be installed to automatically control the fan speeds according to
the CPU’s temperature.
• If there are not enough ports on the mainboard to connect all system fans, adapters
are available to connect a fan directly to a power supply.
• Before first boot up, ensure that there are no cables impeding any fan blades.
En-19
English
The fan power connectors support system cooling fans with +12V. If the mainboard has
a System Hardware Monitor chipset on-board, you must use a specially designed fan
with a speed sensor to take advantage of the CPU fan control. Remember to connect
all system fans. Some system fans may not connect to the mainboard and will instead
connect to the power supply directly. A system fan can be plugged into any available
system fan connector.

BIOS Setup
CLICK BIOS II is developed by MSI that provides a graphical user interface for setting
parameters of BIOS by using the mouse and the keybord.
With the CLICK BIOS II, users can change BIOS settings, monitor CPU temperature,
select the boot device priority and view system information such as the CPU name,
DRAM capacity, the OS version and the BIOS version. Users can import and export
parameters data for backup or sharing with friends. After connecting to Internet, users
can browse the internet, check mail and live update your system.

• If you do not have any EMI problem, leave the setting at [Disabled] for optimal system
stability and performance. But if you are plagued by EMI, select the value of Spread
Spectrum for EMI reduction.
• The greater the Spread Spectrum value is, the greater the EMI is reduced, and the
system will become less stable. For the most suitable Spread Spectrum value, please
consult your local EMI regulation.
• Remember to disable Spread Spectrum if you are overclocking because even a slight
jitter can introduce a temporary boost in clock speed which may just cause your
overclocked processor to lock up.
