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.

Hardware Setup

Central Processing Unit: CPU

The mainboard supports AMD® Athlon64/ Sempron processor. The mainboard uses a CPU socket called Socket-754 for easy CPU installation. 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.

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.

CPU Installation Procedures for Socket 754

1.Please turn off the power and unplug the power cord before installing the CPU.

2. Pull the lever sideways away from the socket. Make sure to raise the lever up to a 90-de- gree angle.

G old arrow

3. Look for the gold arrow. The gold arrow should point as picture shown. The CPU can only fit in the correct orientation.

4.If the CPU is correctly installed, the pins should be completely embedded into the socket and can not be seen. Please note that any violation of the correct installation proc edures may cause permanent damages to your mainboard.

5.Press the CPU down firmly into the socket and close the lever. As the CPU is likely to move while the lever is being closed, always close the lever with your fingers pressing tightly on top of the CPU to make sure the CPU is properly and completely embedded into the socket.

Installing AMD Athlon64 CPU Cooler Set

W hen 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.

1.Position the cooling set onto the retention mechanism. Hook one end of the clip to hook first.

4. Fasten down the lever.

2.Press down the other end of the clip to fasten the cooling set on

t h e t o p o f t h e r e t en t i o n mechanism.

3.Locate the Fix Lever, Safety Hook and the Fixed Bolt. Lift up the intensive fixed lever.

5.Make sure the safety hook completely clasps the fixed bolt of the retention mechanism.

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

MSI Reminds You...

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.

MS-7181 Micro-ATX M ainboard

Memory

The 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).

For the updated supporting memory modules, please visit http://www.msi.com.tw/ program/products/mainboard/mbd/pro_mbd_trp_list.php.

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- 6

Hardware Setup

DDR DIMM 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 singleor double-sided modules to meet your own needs.

Memory modules can be installed in any combination as follows:

Slot	Memory Module	Total Memory
DIMM 1	S/D	64MB~1GB
(Bank 0 & 1)
DIMM 2	S/D	64MB~1GB
(Bank 2 & 3)
Maximum System Memory Supported		64MB~2GB
S: Single Side	D: Double Side

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.

Volt Notch

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: 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.

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 100oC, 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.

Connectors

The mainboard provides connectors to connect FDD, IDE HDD, front panel of the system case, audio ports, USB Ports, and CPU/System FANs.

Floppy Disk Drive Connector: FDD1

The mainboard provides a standard floppy disk drive connector that supports 360KB, 720KB, 1.2MB, 1.44MB and 2.88MB floppy disk types.

FDD1

Fan Power Connectors: CPUFAN1, SFAN1

The CPUFAN1 (processor fan) and SFAN1 (system fan) support system cooling fan with +12V. It supports 3-pin head connector. W hen connecting the wire to the connectors, always take 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.
