2.2 CPU
The mainboard supports Intel® Pentium® M Dothan/Celeron M processor in the 478 pin package. The mainboard uses a CPU socket called mPGA478
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.
(For the latest information about CPU, please visit http://www.msi.com.tw/program/products/slim_pc/slm/pro_slm_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.
2-3
CPU & Cooler Set Installation
1. Loose the screw on the CPU socket with a tank screwdriver in clockwise
direction.
2. Place the CPU on top of the socket. Make sure to align the gold arrow on the
CPU with the arrow key on the socket.
4. On the front end of the CPU socket is a
locking mechanism designed into the form
of a screw. Make sure that you actuate
or deactuate this mechanism with a
screwdriver before and after installing
the CPU.
3. Push the CPU down until its
pins securely fit into the socket.
5. Lift up the levers on both sides.
2-4
Chapter 2 - Mainboard Hardware
5. Mount the cooler set (fan & heatsink
bundled) on top of the CPU and fit it
into the retention mechanism.
6. Secure the levers to lock the cooler
set.
7. Connect the fan power cable from
the mounted fan to the 3-pin fan
power connector on the board.
2-5
2.3 Memory
The mainboard supports up to 2GB of DDR333 (two 184-pin 333MHz
non-ECC DDR DIMMs) or DDR-II 400/533 (two 240-pin 400/533MHz non-ECC
DDR-II DIMMs) system memory. Please note that only one type of memory (all
DDR or all DDR-II, no mixture allowed) can be used at one time.
(For more information on compatible components, please visit http://www.msi.
com.tw/program/products/mainboard/mbd/pro_mbd_trp_list.php.)
DIMM4 (DDR-II 400/533)
DIMM3 (DDR-II 400/533)
DIMM2 (DDR333)
DIMM1 (DDR333)
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.
MSI Reminds You...
You can barely see the golden finger if the module is properly
inserted in the socket.
3. The plastic clip at each side of the DIMM slot will automatically close.

Memory Population Rules
This mainboard supports DDR333 (DIMM1 & DIMM2) or DDR-II 400/533
(DIMM3 & DIMM4) memory interface.
Each DIMM slot supports up to a maximum size of 1GB. Users can install
either single- or double-sided modules depending on their needs. Please note
that only one type of memory (all DDR or all DDR-II, no mixture allowed) can be
used at one time.
Slot Memory Module Total Memory
DIMM1 or DIMM3 S/D 64MB~1GB
DIMM2 or DIMM4 S/D 64MB~1GB
Maximum System Memory Supported 64MB~2GB
S: Single Side D: Double Side
MSI Reminds You...
Make sure that you install memory modules of the same type and
density on DDR DIMMs.

2.4 Power Supply
The mainboard supports SSI power supply for the power system. Before inserting the power supply connector, always make sure that all compo-
nents are installed properly to ensure that no damage will be caused.
SSI 24-Pin System Power Connector: ATX1
This connector allows you to connect an SSI power supply. To connect
the SSI 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 or 24-pin SSI power supply
as you like. If you’d like to use the 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.
SSI 8-Pin CPU Power Connector: JPW1
This connector provides 12V power output to the CPU.
