Chapter 2
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)
This mainboard supports Intel®processor in LGA 775 package. W hen 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.
Introduction to LGA 775 CPU
The surface of LGA 775 CPU.
Remember to apply some ther-
mal paste on it for better heat
dispersion.

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.

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. Remove the cap from lever hinge
side (as the arrow shows).
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.
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.
3. The pins of socket reveal. 4. Open the load lever.

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 align-
ment keys are matched.
8. Cover the load plate onto the
package.
7. Visually inspect if the CPU is
seated well into the socket. If not,
take out the CPU with pure vertical
motion and reinstall.

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 con-
firm that the clip-ends are cor-
rectly inserted.
11. Press the four hooks down to fas-
ten the cooler. Then rotate the lock-
ing switch (refer to the correct di-
rectionmarkedonit)tolockthe
hooks.
9. Press down the load lever lightly
onto the load plate, and then se-
cure the lever with the hook under
retention tab.

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 depend-
ing on the model you purchase.

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. The following illustrations explain the population rules for Dual-Channel
mode.

MS-7380 Mainboard
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.
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.
3. The plastic clip at each side of the DIMM slot will automatically close.
Volt Notch
Important
You can barely see the golden finger if the module is properly inserted in the
DIMM slot.

1. Make sure that all the connectors are connected to proper ATX power sup-
plies to ensure stable operation of the mainboard.
2. Power supply of 450 watts (and above) is highly recommended for system
stability.
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 sup-
ply 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.
ATX 8-Pin Power Connector: JPWR2
This power connector is used to provide power to the CPU.

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.

Important
1. Please refer to the recommended CPU fans at processor’s official website
or consult the vendors for proper CPU cooling fan.
2. Fan/heatsink with 3 or 4 pins are both available for CPUFAN1.
Fan Power Connectors: CPUFAN1, SYSFAN1
The fan power connectors support system cooling fan with +12V. When connecting
the wire to the connectors, always note that the red wire is the positive and should
be connected to the +12V; the black wire is Ground and should be connected to GND.
If the mainboard has a System Hardware Monitor chipset on-board, you must use a
specially designed fan with speed sensor to take advantage of the CPU fan control.
