FCC-B Radio Frequency Interference Statement
This equipment has been tested and found to comply with the limits for a class
B digital device, pursuant to part 15 of the FCC rules. These limits are designed
to provide reasonable protection against harmful interference when the equip-
ment is operated in a commercial environment. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in accor-
dance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to
cause harmful interference, in which case the user will be required to correct
the interference at his own expense.
Notice 1
The changes or modifications not expressly approved by the party respon-
sible for compliance could void the user’s authority to operate the equipment.
Notice 2
Shielded interface cables and A.C. power cord, if any, must be used in order to
comply with the emission limits.

Central Processing Unit: CPU
The mainboard supports Intel®Pentium 4 / Celeron DTM (LGA775) processor. The
mainboard uses a CPU socket called LGA775. When you are installing the CPU, make
sure to install the heat sink/cooler to prevent overheating. If you do not have
the CPU, contact your dealer to purchase and install them before turning on the computer.

MSI Reminds You...
Overheating
Overheating will seriously damage the CPU and system, always make
sure the cooling fan can work properly to protect the CPU from
overheating.
Replacing the CPU
While replacing the CPU, always turn off the ATX power supply or
unplug the power supply’s power cord from grounded outlet first to
ensure the safety of CPU.
The surface of LGA 775 CPU.
Remember to apply some silicone
heat transfer compound on it for
better heat dispersion.

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. Al-
ways cover it to protect the socket
pin until you are going to install the
CPU.
CPU, Heatsink & Fan Installation
When you are installing the CPU, make sure the CPU has a heat sink/
cooler fan attached on the top to prevent overheating. If you do not have the
heat sink/cooler fan, 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 heatsinking.
Follow the steps below to install the CPU & cooling fan correctly. Wrong instal-
lation will cause the damage of your CPU & mainboard.
4. Open the load lever.3. The pins of socket reveal.

6. After confirming the CPU direction
for correction mating, put down the
CPU in the socket housing frame.
Be sure to grape on the edge of the
substrate. Note that the alignment
keys are matched.
8. Rotate 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 purely vertical motion
and reload it again.

10. Align the holes on the mainboard
with the heatsink first. Pull down
the fan/heatsink until its four clips
get wedged in the holes of the
mainboard.
12.Turn over the mainboard to con-
firm that the clip-ends are cor-
rected inserted.

11. Press the four hooks down to fas-
ten the fan. Then rotate the locking
switch (refer to the correct direc-
tion marked on it) to lock the hooks
again.
9. Engage the load while pressing
down lightly onto the load plate, and
then secure the lever with the hook
under retention tab.
MSI Reminds You...
1. Confirm if your CPU heatsink/cooler is firmly installed before
turning on your system.
2. Check the information in PC Health Status of H/W Monitor in
BIOS (refer to p.3-20 for details) for the CPU temperature.
3. Make sure that the CPU socket pins are not turned up or pressed
down.

DDR DIMM Slots
(DDR 1~2)
Introduction to DDR SDRAM
DDR (Double Data Rate) SDRAM is similar to conventional SDRAM, but doubles the rate
by transferring data twice per cycle. It uses 2.5 volts as opposed to 3.3 volts used in
SDR SDRAM, and requires 184-pin DIMM modules rather than 168-pin DIMM modules
used by SDR SDRAM.

MS-7082 Micro ATX Mainboard
DDR Module Combination
Install at least one DIMM module on the slots. Memory modules can be installed on the
slots in any order. You can install either single- or double-sided modules to meet your
own needs.
Memory modules can be installed in any combination as follows:
Installing DDR Modules
1. The DDR DIMM has only one notch on the center of module. The module 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.
MSI Reminds You...
You can barely see the golden finger if the module is properly
inserted in the socket.

Power Supply
The mainboard supports ATX power supply for the power system. Before inserting the
power supply connector, always make sure that all components are installed properly
to ensure that no damage will be caused.
ATX 20-Pin Power Connector: CONN1
This connector allows you to connect to an ATX power supply. To connect to the ATX
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.
ATX 12V Power Connector: JPW2000
This 12V power connector is used to provide power to the CPU.
MSI Reminds You...
Power supply of 300-watt (and above) is highly recommended for
system stability.
