Chapter 2
This chapter provides you with the information about
hardware setup procedures. While doing the installa-
tion, 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 compo-
nents.

Hardware Setup
CPU (Central Processing Unit)
This mainboard supports Intel®Pentium 4 Cedar Mill processor in LGA 775 package.
When you are installing the CPU, make sure to install the cooler to prevent
overheating. If you do not have the CPU cooler, contact your dealer to purchase and
install them before turning on the computer.
For the latest information about CPU, please visit http://www.msi.com.tw/program/
products/mainboard/mbd/pro_mbd_cpu_support.php.
Important
1. Overheating will seriously damage the CPU and system. Always make
sure the cooling fan can work properly to protect the CPU from overheat-
ing.
2. Make sure that you apply an even layer of heat sink paste (or thermal tape)
between the CPU and the heatsink to enhance heat dissipation.
3. 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.

2. Remove the cap from lever hinge
side (as the arrow shows).
1. The CPU 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.
CPU & Cooler Installation
When you are installing the CPU, make sure the CPU has a cooler at-
tached on the top to prevent overheating. If you do not have the cooler, contact
your dealer to purchase and install them before turning on the computer. Meanwhile,
do not forget to apply some silicon heat transfer compound 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.
4. Open the load lever.

Hardware Setup
Important
1.Confirm if your CPU cooler is firmly installed before turning on your sys-
tem.
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.
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 theload plate onto the pack-
age.
7. Visually inspect if the CPU is
seated well into the socket. If not,
take out the CPU with pure vertical
motion and reinstall.

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

MS-7275 Mainboard
2-6
Important
1.Check the information in PC Health Status of H/W Monitor in BIOS (Chap-
ter 3) for the CPU temperature.
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. Please note that the mating/unmating durability of the CPU is 20 cycles.
Therefore we suggest you do not plug/unplug the CPU too often.
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-
rection marked on it) to lock the
hooks.
9. Press down the load lever lightly
onto the load plate, and then se-
cure the lever with the hook under
retention tab.

Memory
The mainboard provides two 240-pin non-ECC DDRII DIMMs.
For more information on compatible components, please visit http://www.msi.com.tw/
program/products/mainboard/mbd/pro_mbd_trp_list.php.

DDRII
240-pin, 1.8V
Important
- DDRII modules are not interchangeable with DDR and the DDRII standard is
not backwards compatible. You should always install DDRII memory mod-
ules in the DDRII DIMMs and DDR memory modules in the DDR DIMMs.
- To enable successful system boot-up, always insert the memory modules
into the DIMM1 first.
Installing DDRII Modules
1. The memory module has only one notch on the center and will only fit in the right
orientation.
2. Insert the DIMM memory module vertically into the DIMM slot. Then push it in until the
golden finger on the memory module is deeply inserted in the socket.
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
socket.

1. Maker sure that all the connectors are connected to proper ATX power sup-
plies to ensure stable operation of the mainboard.
2. Power supply of 350 watts (and above) is highly recommended for system
stability.
3. ATX 12V power connection should be greater than 18A.
ATX 24-Pin Power Connector: ATX1
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 connec-
tor.
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.
