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, cont act 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 & cool er correctly. Wrong installation will cause the 
damage to your CPU & mainboard. 
 
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 has a plastic cap on it to prot ect 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 fi ngers 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.    Make sure 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 damage. 
4.    Whenever CPU is not installed, always prot ect your CPU socket pins with the plastic cap 
covered to avoid damage. 
5.    Please note that the mating/unmating durab ility of the CPU is 20 cycles. Therefore, we 
suggest you do not plug/unplug the CPU too often. 
 
Memory 
The mainboard provides two 184-pin unbuffered DDR333 / DDR400 DDR SDRAM, and supports 
the memory size up to 2GB. To operate properly, at least one DIMM module must be installed. 
(For the updated supporting memo ry modules, please visit 
http://www.msi.com.tw/program/produc ts/mainboard/mbd/pro_mbd_trp_list.php)
 
Install at least one DIMM module on the slots. Me mory modules can be installed on the slots in 
any order. You can install either single- or  double-sided modules to meet your own needs. 
Installing DDR Modules 
Notch
Vol t1.  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 t he 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.

supports 360K, 720K, 1.2M, 1.44M and 2.88M floppy disk types.   
 
IDE Connector: IDE1/IDE2 
The mainboard has dual Ultra DMA 66/100/133 controller that provides PIO mode 0~4, 
Bus Master, and Ultra DMA 66/100/133 function.  You can connect up to four hard disk 
drives, CD-ROM, 120MB Floppy and other devices. 
The first hard drive should always be connec ted to IDE1. IDE1 can connect a Master 
and a Slave drive. You must configure sec ond hard drive to Slave mode by setting the 
jumper accordingly. 
  
MSI Reminds You...   
If you install two hard disks on one cable, you must configure the second drive to Slave mode by 
setting its jumper. Refer to the hard disk documentation supplied by hard disk vendors for jumper 
setting instructions.  
 
Serial ATA Connectors controlled by VIA® 8237R Plus: SATA1/SATA2 
The mainboard provides dual high-speed Se rial ATA interface ports. The ports 
supper 1st generation Serial ATA data rates of 150MB/s and are fully compliant with 
Serial ATA 1.0 specifications. Each Seri al ATA connector can connect to 1 hard disk 
device.
