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.
