Safety Information

y The components included in this package are prone to damage from electrostatic
discharge (ESD). Please adhere to the following instructions to ensure successful
computer assembly.

y Ensure that all components are securely connected. Loose connections may cause
the computer to not recognize a component or fail to start.

y Hold the motherboard by the edges to avoid touching sensitive components.

y It is recommended to wear an electrostatic discharge (ESD) wrist strap when
handling the motherboard to prevent electrostatic damage. If an ESD wrist strap is
not available, discharge yourself of static electricity by touching another metal object
before handling the motherboard.

y Store the motherboard in an electrostatic shielding container or on an anti-static pad
whenever the motherboard is not installed.

y Before turning on the computer, ensure that there are no loose screws or metal
components on the motherboard or anywhere within the computer case.

y Do not boot the computer before installation is completed. This could cause
permanent damage to the components as well as injury to the user.

y If you need help during any installation step, please consult a certified computer
technician.

y Always turn off the power supply and unplug the power cord from the power outlet
before installing or removing any computer component.

y Keep this user guide for future reference.

y Keep this motherboard away from humidity.

y Make sure that your electrical outlet provides the same voltage as is indicated on the
PSU, before connecting the PSU to the electrical outlet.

y Place the power cord such a way that people can not step on it. Do not place anything
over the power cord.

y All cautions and warnings on the motherboard should be noted.

y If any of the following situations arises, get the motherboard checked by service
personnel:

 Liquid has penetrated into the computer.
 The motherboard has been exposed to moisture.
 The motherboard does not work well or you can not get it work according to user

guide.

 The motherboard has been dropped and damaged.
 The motherboard has obvious sign of breakage.

CPU Socket

Introduction to the LGA 2066 CPU

The surface of the LGA2066 CPU has
four alignment keys and a yellow triangle
to assist in correctly lining up the CPU
for motherboard placement. The yellow
triangle is the Pin 1 indicator.

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

Important

y

Always insert a memory module in the DIMMC1 slot first.

y

To ensure system stability for Dual/ Triple/ Quad channel mode, memory modules
must be of the same type, number and density. And for every channel, the odd number
DIMM slot must to be installed first.

y

Due to chipset resource usage, the available capacity of memory will be a little less
than the amount of installed.

y

Based on Intel CPU specification, the Memory DIMM voltage below 1.35V is
suggested to protect the CPU.

y

Please note that the maximum capacity of addressable memory is 4GB or less
for 32-bit Windows OS due to the memory address limitation. Therefore, we
recommended that you to install 64-bit Windows OS if you want to install more than
4GB memory on the motherboard.

y

Some memory may operate at a lower frequency than the marked value when
overclocking due to the memory frequency operates dependent on its Serial Presence
Detect (SPD).

y

It is recommended to use a more efficient memory cooling system for full DIMMs
installation or overclocking.

y

The stability and compatibility of installed memory modules depend on installed CPU
and devices when overclocking.

For a single PCIe x16 expansion card installation with optimum performance, using

the PCI_E1 slot is recommended.

If you install a large and heavy graphics card, you need to use a tool such as MSI

Gaming Series Graphics Card Bolster to support its weight and to prevent deformation
of the slot.

When adding or removing expansion cards, always turn off the power supply and

unplug the power supply power cable from the power outlet. Read the expansion
card’s documentation to check for any necessary additional hardware or software
changes.
