CPU (Central Processing Unit)
When you are installing the CPU, make sure to install the cooler to prevent
overheating. If you do not have the CPU cooler, consult your dealer before turning
on the computer.
For the latest information about CPU, please visit http://global.msi.com.tw/index.
php?func=cpuform
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.
Replacing 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.

CPU & Cooler Installation
When you are installing the CPU, make sure the CPU has a cooler attached on
the top to prevent overheating. Meanwhile, do not forget to apply some thermal
paste on CPU before installing the heat sink/cooler fan for better heat dispersion.
Follow the steps below to install the CPU & cooler correctly. Wrong installation will
cause the damage of your CPU & mainboard.
1.The CPU socket has a plastic cap
on it to protect the contact from
damage. Before you install the CPU,
always cover it to protect the socket
pin.
2.Remove the cap from lever hinge
side (as the arrow shows).
3.The pins of socket reveal.
4.Open the load lever.
Important
1.Confirm if your CPU cooler is firmly installed before turning on your system.
2. Do not touch the CPU socket pins to avoid damaging.
3. The availability of the CPU land side cover depends on your CPU packing.
En-6
5.Lift the load lever up and open the
load plate.
6.After confirming the CPU direction
for correct mating, put down the
CPU in the socket housing frame.
Be sure to grasp on the edge of
the CPU base. Note that the alignment keys are matched.

English
7.Visually inspect if the CPU is
seated well into the socket. If not,
take out the CPU with pure vertical
motion and reinstall.
8.Cover the load plate onto the
package.
En-7
MS-7392 Mainboard
9.Press down the load lever lightly
onto the load plate, and then secure the lever with the hook under
retention tab.
11.Press the four hooks down to fasten
the cooler. Then rotate the locking
switch (refer to the correct direction
marked on it) to lock the hooks.
10. Align the holes on the mainboard
with the heatsink. Push down the
cooler until its four clips get
wedged into the holes of the
mainboard.
12.Turn over the mainboard to confirm that the clip-ends are correctly
inserted.

Important
1. Read the CPU status in BIOS (Chapter 3).
2. Whenever CPU is not installed, always protect your CPU socket pin with the
plastic cap covered (shown in Figure 1) to avoid damaging.
3. Mainboard photos shown in this section are for demonstration of the CPU/
cooler installation only. The appearance of your mainboard may vary depending on the model you purchase.

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. The plastic
clip at each side of the DIMM slot will automatically close when the memory module
is properly seated.
Important
You can barely see the golden finger if the memory module is properly inserted in the DIMM slot.
3. Manually check if the memory module has been locked in place by the DIMM slot
clips at the sides.
Volt
Notch
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 3+GB (not full 4GB) when each DIMM is installed with a 1GB
memory module.

Power Supply
ATX 24-Pin Power Connector: ATX1
This connector allows you to connect an ATX 24-pin power supply.
To connect the ATX 24-pin power supply, make sure the plug of the
power supply is inserted in the proper orientation and the pins are
aligned. Then push down the power supply firmly into the connector.
You may use the 20-pin ATX power supply as you like. If you’d like
to use the 20-pin ATX power supply, please plug your power supply along with pin 1 & pin 13 (refer to the image at the right hand).
There is also a foolproof design on pin 11, 12, 23 & 24 to avoid
wrong installation.
