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=cpuform2
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 motherboard 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.
English
En-5
MS-7577 Mainboard
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 & motherboard.
1.Pull the lever sideways away from
the socket. Make sure to raise the
lever up to a 90-degree angle.
3.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 motherboard.
2.Look for the gold arrow of the CPU.
The gold arrow should point as
shown in the picture. The CPU can
only fit in the correct orientation.
4. 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.
En-6
5.Position the cooling set onto the retention mechanism.
Hook one end of the clip to hook first.
6. 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 .
English
7.Fasten down the lever. 8.Attach the CPU Fan cable to the CPU
fan connector on the motherboard.
Important
1.Motherboard photos shown in this section are for demonstration only. The
appearance of your motherboard may vary depending on the model you
purchase.
2.While disconnecting the Safety Hook from the fixed bolt, it is necessary to
keep an eye on your fingers, because once the Safety Hook is disconnected
from the fixed bolt, the fixed lever will spring back instantly.

Dual-Channel Memory Population Rules
In Dual-Channel mode, the memory modules can transmit and receive data with two
data bus lines simultaneously. Enabling Dual-Channel mode can enhance the system
performance. Please refer to the following illustrations for population rules under

Important
-DDR3 memory modules are not interchangeable with DDR2 and the DDR3
standard is not backwards compatible. You should always install DDR3
memory modules in the DDR3 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.
En-8
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.

Power Supply
ATX 24-pin Power Connector: JPWR1
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).
