This chapter provides you with the information about
hardware setup procedures. While doing the installation,
be careful in holding the components and follow the
installation procedures. For some components, if you
install in the wrong orientation, the components will not
work properly.
Use a grounded wrist strap before handling computer
components. Static electricity may damage the

Hardware Setup
The mainboard supports AMD® Phenom/Athlon/Sempron processors. The mainboard
uses a CPU socket called Socket AM2+ for easy CPU installation. When you are
installing the CPU, make sure the CPU has a heat sink and a cooling fan
attached on the top to prevent overheating. If you do not have the heat sink and
cooling fan, contact your dealer to purchase and install them before turning on the
computer.
For the latest information about CPU, please visit http://global.msi.com.tw/index.php?
func=cpuform
CPU (Central Processing Unit)
Important
Overheating
Overheating will seriously damage the CPU and system. Always make sure
the cooling fan can work properly to protect the CPU from overheating. Make
sure that you apply an even layer of thermal paste (or thermal tape) between
the CPU and the heatsink to enhance heat dissipation.
Replaceing the CPU
While replacing the CPU, always turn off the ATX power supply or unplug the
power supply’s power cord from the grounded outlet first to ensure the safety
of CPU.
Overclocking
This mainboard is designed to support overclocking. However, please make
sure your components are able to tolerate such abnormal setting, while
doing overclocking. Any attempt to operate beyond product specifications is
not recommended. We do not guarantee the damages or risks caused
by inadequate operation or beyond product specifications.

MS-7376 Mainboard
CPU Installation Procedures for Socket AM2+
1.Please turn off the power and
unplug the power cord before
installing the CPU.
2.Pull the lever sideways away
from the socket. Make sure to
raise the lever up to a 90-degree angle.
3.Look for the gold arrow on the
CPU. The gold arrow should point
as shown in the picture. The CPU
can only fit in the correct
orientation.Lower the CPU down
onto the socket.
4.If the CPU is correctly installed,
the pins should be completely
embedded into the socket and
can not be seen. Please note
that any violation of the correct
installation procedures may
cause permanent damages to
your mainboard.
5. Press the CPU down firmly into
the socket and close the lever.
As the CPU is likely to move while
the lever is being closed, always close the lever with your
fingers pressing tightly on top of
the CPU to make sure the CPU is
properly and completely embedded into the socket.

Installing AMD Socket AM2+ CPU Cooler Set
When you are installing the CPU, make sure the CPU has a heat sink and a
cooling fan attached on the top to prevent overheating. If you do not have the
heat sink and cooling fan, contact your dealer to purchase and install them before
turning on the computer.
2. Then press down the other end of
the clip to fasten the cooling set on
the top of the retention mechanism.
Locate the Fix Lever and lift up it .
1.Position the cooling set onto the retention mechanism.
Hook one end of the clip to hook
first.
3.Fasten down the lever.
4.Attach the CPU Fan cable to the CPU
fan connector on the mainboard.

Important
1. Read the CPU status in BIOS (Chapter 3).

Hardware Setup
Installing Memory Modules
1. The memory module has only one notch on the center and will only fit in the right
orientation.
2. Insert the memory module vertically into the DIMM slot. Then push it in until the
golden finger on the memory module is deeply inserted in the DIMM slot.
3. The plastic clip at each side of the DIMM slot will automatically close.
Important
You can barely see the golden finger if the memory module is properly inserted
in the DIMM slot.
Important
-DDR2 memory modules are not interchangeable with DDR and the DDR2
standard is not backwards compatible. You should always install DDR2
memory modules in the DDR2 DIMM slots.
-In Dual-Channel mode, make sure that you install memory modules of the
same type and density in different channel DIMM slots.
-To enable successful system boot-up, always insert the memory modules
into the DIMM1 first.
- Due to the chipset resource deployment, the system density will only be
detected up to 7+GB (not full 8GB) when each DIMM is installed with a 2GB
memory module.
