Hardware Setup
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
components.

Hardware Setup
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.
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.

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. Open the load level.
3. The CPU socket has a plastic cap on it
to protect the contack from damage.
Before you install CPU, always cover
it to protect the socket pin. Romove
the cap from the lever hinge side (as
the arrow shows).
2.Lift the load lever up and open the
load plate.
4.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.

Hardware Setup
5.Visually inspect if the CPU is seated
well into the socket. If not, take out
the CPU with pure vertical motion and
reinstall.
7.Press down the load lever lightly onto
the load plate, and then secure the
lever with the hook under retention
tab.
6.Cover the load plate onto the
package.
8.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.
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.

Important
1. Read the CPU status in BIOS.
2. Whenever CPU is not installed, always protect your CPU socket pin with the
plastic cap covered (shown in Figure 1) to avoid damaging.

Memory Population Rules
Please refer to the following illustrations for memory population rules.
Single-Channel mode
When you have only one memory module, please always insert it into the DIMM_A0
first (as way 1 shown in below).

Dual-Channel mode
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. When you have two memory modules, please always insert them into
the DIMM_A0 & DIMMB0 (as way 2 shown in below).

Three-Channel mode
In Three-Channel mode, the memory modules can transmit and receive data with
three data bus lines simultaneously. Enabling Three-Channel mode can enhance the
best system performance. When you have three or more memory modules, please
always insert them as the way 3/ 4/ 5/ 6 (shown in below) to get the best system
performance.

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 Three-/ Dual- channel mode, make sure that you install memory modules of
the same type and density in different channel DIMM slots. If the speeds of
installed memeory modules are different (ex. 1066 & 1333), the system will
detect and operate the lower speed (1066) with all installed memory modules.
- Please always install the same type and density memory modules in DIMM
slots to avoid the damage of memory.
-To enable successful system boot-up, always insert the memory modules
into the DIMM_A0 first.
- Due to the chipset resource deployment, the system density will only be
detected up to 23+GB (not full 24GB) when each DIMM is installed with a 4GB
memory module.
- When you install incorrect memory module (the SA2-pin of the memory
module connects to Ground) in the DIMM_C0/C1, the LED beside DIMM_C0
will light red color to remind you. The position of the LED is shown as below.
Double confirm with your memory module vender for the third channelsupports.

MS-7520 Mainboard
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.
