CPU (Central Processing Unit)
W hen 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 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.
En-5
English
MS-7576 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 & mainboard.
1.Pull the lever sideways away from the socket. Make sure to raise the lever up to a 90-degree angle.
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.
3. If the CPU is correctly installed, the p i n s s h o u l d b e c o m p l et el y 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.
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.
7. Fasten down the lever.
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 .
8.Attach the CPU Fan cable to the CPU fan connector on the mainboard.
English
Important
1.Mainboard photos shown in this section are for demonstration of the cooler installation for Socket AM2+ CPUs only. The appearance of your mainboard 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.

Installing Memory Modules |
|
|
1. The memory module has only one notch on the center and will only fit in the right |
|
|
orientation. |
English |
|
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
-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 DDR DIMMs.
-To enable successful system boot-up, always insert the memory modules into the DIMM1 first.

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). There is also a foolproof design on pin 11, 12, 23 & 24 to avoid wrong installation.
