							2-5 Hardware SetupInstalling AMD Athlon64 CPU Cooler Set
When you are installing the CPU, make sure the CPU has a heat sink and a
cooling fan attached on the top to prevent overheating.  If you do not have the
heat sink and cooling fan, contact your dealer to purchase and install them before
turning on the computer.
4.Fasten down the lever.
5.Make sure the safety hook
completely clasps the fixed
bolt of the retention
mechanism. 2.Press down the other end of the
clip to fasten the cooling set on
the top of the retention
mechanism. 1.Position the cooling set onto the
retention mechanism. Hook one
end of the clip to hook first.
3.Locate the Fix Lever, Safety Hook
and the Fixed Bolt. Lift up the in-
tensive fixed lever.Safety

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. 6. Connect the fan power cable
from the mounted fan to the
CPUFAN1 connector on the
board 
						

							2-6MS-7181 Micro-ATX MainboardThe mainboard provides two slots for 184-pin DDR SDRAM DIMM (Double In-Line
Memory Module) modules and supports up to 2GB memory size. You can install
PC3200/DDR400, PC2700/DDR333 & PC2100/DDR266 modules on the DDR DIMM slots
(DDR 1~2).

DDR DIMM Slots
(DIMM1~2)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.  High memory bandwidth makes DDR an ideal solution
for high performance PC, workstations and servers. 
						

							2-7 Hardware SetupInstall 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: DDR DIMM Module Combination
S: Single SideD: Double Side Slot Memory Module Total Memory DIMM 1  
(Bank 0 & 1) S/D 64MB~1GB DIMM 2  
(Bank 2 & 3) S/D 64MB~1GB Maximum System Memory Supported 64MB~2GB 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.VoltNotchMSI Reminds You...
You can barely see the golden finger if the module is properly inserted
in the socket. 
						

							2-8MS-7181 Micro-ATX MainboardPower 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: JWR1
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: JPW1
This 12V power connector is used to provide power to the CPU.

There is a mechanism of this mainboard to protect it from being
damaged. The power will shut down automatically in two conditions: the
temperature of CPU reaches 100o
C, or the low voltage occurs during
booting up. Please follow the instructions below for this issue:
1. The power LED will blink continously. You should unplug the power
cord or turn off the power switch.
2.After the power LED stop blinking, plug on the power cord or turn on
the power switch, then you can reboot your system again.
