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.

CPU (Central Processing Unit)

Hardware Setup

This mainboard supports Intel

®

processor in LGA 775 package. When you are install-

ing 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.

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.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.

3.The pins of socket reveal.

2.Remove the cap from lever hinge
side (as the arrow shows).

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.

2-4

Hardware Setup

5.Lift the load lever up and open the
load plate.

7.Visually inspect if the CPU is
seated well into the socket. If not,
take out the CPU with pure vertical
motion and reinstall.

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.

8.Cover the load plate onto the
package.

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 fas-

ten the cooler. Then rotate the lock­ing switch (refer to the correct di­rection marked on it) to lock the
hooks.

switch

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.

Important

You can barely see the golden finger if the module is properly inserted in the
DIMM slot.

3. The plastic clip at each side of the DIMM slot will automatically close.

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 7+GB (not full 8GB) when each DIMM is installed with a 2GB
memory module.

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.

Important Notification about Power Issue

NForce chipset is very sensitive to ESD (Electrostatic Discharge), therefore this
issue mostly happens while the users intensively swap memory modules under S5
(power-off) states, and the power code is plugged while installing modules. Due to
several pins are very sensitive to ESD, so this kind of memory-replacement actions
might cause system chipset unable to boot. Please follow the following solution to
avoid this situation.

Unplug the AC power cable (shown in figure 1) or unplug the power connectors
(shown in figure 2 & figure 3) before the 1st installation or during system upgrade
procedure.
