 Hardware Setup 
This chapter tells you how to install the CPU, memory modules, and expansion cards, as well as 
how to setup the jumpers on the mainboard. It also provides the instructions on connecting the 
peripheral devices, such as the mouse, keyboard, etc. While doing the installation, be careful in 
holding the components and follow the installation procedures. 
 Central Processing Unit: CPU 
The mainboard supports Intel Pentium 4 Prescott processor. The mainboard uses a CPU socket 
called LGA775. 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. 
 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. Overclocking This motherboard is designed to support overclocking. However, please make sure your components are able to tolerate such abnormal setting, while doing overclocking. Any attempt to operate beyond product specifications is not recommended. We do not guarantee the damages or risks caused by inadequate operation or beyond product specifications.  LGA775 CPU and Cooler Installation (CPU Clip is optional) 
When you are installing the CPU, make sure the CPU has a cooler attached 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 cooler for better heat dispersion. 
Follow the steps below to install the CPU & cooler correctly. Wrong installation will cause the 
damage of your CPU & mainboard. Parallel portCOM port Mouse

5  1. The CPU has a land side cover on the bottom to protect the CPU contact from damage. 
Rotate it to make the pin 1 indicator (yellow triangle) in the left-bottom 
corner. The availability of it depends on the CPU packing. 
2. Take out the accompanying CPU Clip (shown in the right) and rotate it 
for the same direction as the CPU (Pin 1 indicator is in the left-bottom 
corner). 
3. Use 2 hands to remove the land side cover (if any). Please note not to touch the pins. 
4. Align the two pin 1 indicators (the triangles on the CPU & the CPU Clip), and use the CPU 
Clip to clip the CPU up, pressing the clips on both sides to the center, as the arrows 
shown.  
5. The CPU socket has a plastic cap on it to protect the contact from damage. Before you 
have installed the CPU, always cover it to protect the socket pin. 
6. Remove the cap from lever hinge side. The pins of socket reveal.  
7. Lift the load lever up and open the load plate. 
8. Correctly align the triangle of CPU Clip with the CPU chamfer, and 
the square on the CPU Clip to the hook of the socket. 
9. Use your thumb and the middle fingers to push the clips to release 
the CPU, then press down the CPU with your index finger to allow 
the whole module to be installed onto the CPU socket. 
10. The CPU is installed well on the CPU socket. 
11. Visually inspect if the CPU is seated well into the socket, then 
remove the CPU Clip with 2 fingers. Then cover the load plate onto 
the package.  
12. Press down the load lever lightly onto the load plate, and then secure 
the lever with the hook under retention tab. 
13. Align the holes on the mainboard with the cooler. Push down the 
cooler until its four clips get wedged into the holes of the mainboard. 
14. Press the four hooks down to fasten the cooler. Then rotate the locking switch (refer to the 
correct direction marked on it) to lock the hooks. 
15. Turn over the mainboard to confirm that the clip-ends are correctly inserted. 
Note: If you want to uninstall the CPU, align the 4 points (see Point 8 for details) again and push 
the clip to lift up the CPU. 
 
 MSI Reminds You... 1. Confirm if your CPU cooler is firmly installed before turning on your system. 2. Check the information in PC Health Status of H/W Monitor in BIOS for the CPU temperature. 3. Do not touch the CPU socket pins to avoid damaging. 4. Whenever CPU is not installed, always protect your CPU socket pin with the plastic cap covered to avoid damaging. 5. 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.   
						

							 
6 Memory 
The mainboard provides two slots for 184-pin unbuffered DDR400 / 333 and two slots for 240-pin 
unbuffered DDR2 533/ 400 DIMMs. It supports the memory size up to 2GB DDR1 or DDR2 
DIMMs. To operate properly, at least one DIMM module (DDR1 or DDR2) must be installed. 
Since DDR2 modules are not interchangeable with DDR1 and the DDR2 standard is not 
backward compatible, you should always install DDR2 memory module in DDR2 slot (DIMM1 & 
DIMM3), and DDR1 memory module in DDR1 slot (DIMM2 & DIMM4). Wrong installation may 
cause damage of mainboard. Meanwhile, you are not able to boot up your system if you install 
DDR1 & DDR2 memory modules simultaneously. 
(For the updated supporting memory modules, please visit 
http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_trp_list.php) 
Install at least one DIMM module on the slots. You can install either DDR1 or DDR2 modules to 
meet your own needs. 
Installing DDR Modules 
1. The DDR1 or DDR2 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. 
 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. A 300W or above power supply is suggested. 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 connector. 
You may use the 20-pin ATX power supply power supply as you like. If 
you’d like to use the 20-pin ATX power supply, please plug your power 
supply 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 12V Power Connector: JPW1 
This 12V power connector is used to provide power to the CPU. NotchVolt1342GND12VGND12V1122413+3.3V+3.3V-12V+3.3VGNDGNDPS-ON#+5V
