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.

2-3

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.

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 mainboard.

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.

2-4

Hardware Setup

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.

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.

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 differentchannel DDR DIMMs.

-To enable successful system boot-up, always insert the memory modules
into the DIMM1 first.

Bank Interleaving

Bank Interleaving is an important parameter for improving overclocking capability
of memory. It allows system to access multiple banks simultaneously.

Power Down Enable

This is a memory power-saving technology. When the system does not access
memory over a period of time, it will automatically reduce the memory power
supply.

MemClk Tristate C3/ATLVID

This setting allows you to enable/disable the MemClk Tristating during C3 and
ATLVID.

HT Link Speed

This item allows you to set the Hyper-Transport Link speed. Setting to [Auto], the
system will detect the HT link speed automatically.

Adjust PCI-E Frequency (MHz)

This field allows you to select the PCIE frequency (in MHz).

Auto Disable DIMM/PCI Frequency

When set to [Enabled], the system will remove (turn off) clocks from empty DRAM/
PCI slots to minimize the electromagnetic interference (EMI).

CPU Voltage (V)/ CPU-NB Voltage (V)/ CPU VDD Voltage (V)/ CPU-NB VDD
Voltage (V)/ DRAM Voltage (V)/ NB Voltage (V)/ SB Voltage (V)/ HT Link Voltage
(V)

These items are used to asjust the voltage of CPU, Memory and chipset.

Spread Spectrum

When the motherboard’s clock generator pulses, the extreme values (spikes) of the
pulses create EMI (Electromagnetic Interference). The Spread Spectrum function
reduces the EMI generated by modulating the pulses so that the spikes of the pulses
are reduced to flatter curves. If you do not have any EMI problem, leave the setting at
Disabled for optimal system stability and performance. But if you are plagued by EMI,
set to Enabled for EMI reduction. Remember to disable Spread Spectrum if you are
overclocking because even a slight jitter can introduce a temporary boost in clock
speed which may just cause your overclocked processor to lock up.

Important

1.If you do not have any EMI problem, leave the setting at [Disabled] for
optimal system stability and performance. But if you are plagued by EMI,
select the value of Spread Spectrum for EMI reduction.

2.The greater the Spread Spectrum value is, the greater the EMI is reduced,
and the system will become less stable. For the most suitable Spread
Spectrum value, please consult your local EMI regulation.

3.Remember to disable Spread Spectrum if you are overclocking because
even a slight jitter can introduce a temporary boost in clock speed which
may just cause your overclocked processor to lock up.

SATA RAID

The 710 / 750 integrate one SATA host controller
separately, and support RAID function for performance
and reliability.
SATA RAID provides support for RAID 0 (Striping), RAID
1 (Mirroring), RAID 0+1 (Striping & Mirroring) & RAID 5
(striping with parity). RAID 0 greatly improves hard disk
I/O performance by concurrently striping data across
multiple drives. RAID 1 makes sure data is not lost if a
drive fails as data is simultaneously written to two
drives. Drives configured for RAID Striping are said to
form a RAID 0 set, while drives configured for RAID
Mirroring are said to form a RAID 1 set. RAID 0+1 is
implemented as a mirrored array whose segments are
RAID 0 arrays. RAID 0+1 has same fault tolerance as
mirroring and reduces overhead by striping. It needs at
least four drives to form a RAID 0+1. RAID 5 defines
techniques for parity data.
