Chapter 2. 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.  Also, it 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.

= 100MHz  x  20
= 2.0 GHz The mainboard supports Intel
® Pentium® 4 Northwood/Prescott proces-
sor in the 478 pin package. The mainboard uses a CPU socket called PGA478
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 find the heat sink and cooling fan, contact your dealer to pur-
chase and install them before turning on the computer.

Overclocking
This mainboard 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.

CPU Installation Procedures for Socket 478
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-
degree angle.
3. Look for the gold arrow. The
gold arrow should point to-
wards the lever pivot. 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 pro-
cedures 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 com-
pletely embedded into the
socket.

Installing the CPU Fan
As processor technology pushes to faster speeds and higher
performance, thermal management becomes increasingly important. To dissi-
pate heat, you need to attach the CPU cooling fan and heatsink on top of the
CPU. Follow the instructions below to install the Heatsink/Fan:
2.Position the heatsink onto the reten-
tion mechanism.1.Locate the CPU and its retention
mechanism on the mainboard.
3.Mount the fan on top of the heatsink.
Press down the fan until its four clips
get wedged in the holes of the reten-
tion mechanism.4.Press the two levers down to fasten
the fan.  Each lever can be pressed
down in only ONE direction.

Memory
DDR DIMM Slots
(DIMM 1~4, from left to right)
Channel A: DIMM1 & DIMM2 (green)
Channel B: DIMM3 & DIMM4 (purple)
The mainboard provides 4 slots for 184-pin, 2.5V DDR DIMM with 8
memory banks. You can install DDR266 / DDR333 / DDR400 / DDR433 / DDR466
/ DDR500 / DDR533 SDRAM modules on the DDR DIMM slots (DIMM 1~4).
To operate properly, at least one DIMM module must be installed. Please note
that DDR433 / DDR466 / DDR500 / DDR533 are for overclocking spec.  (For
the list of  qualified test memory modules, please refer to P.10 “Memory Mod-
ules” in the appendant Test Report.)
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. Please note that
the DDR SDRAM does not support ECC (error correcting code) and registered
DIMM.
DDR Population Rules
Install at least one DIMM module on the slots. Each DIMM slot supports
up to a maximum size of 1GB. Users can install either single- or double-sided
modules to meet their own needs. Please note that each DIMM can work
respectively for single-channel DDR, but there are some rules while using
dual-channel DDR (Please refer to the suggested DDR population table on p.
2-8). Users may install memory modules of different type and density on
different-channel DDR DIMMs. However, the same type and density memory
modules are necessary while using dual-channel DDR, or instability may happen.

MS-6728 ATX Mainboard
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.
MSI Reminds You...
You can barely see the golden finger if the module is properly
 inserted in the socket.
VoltNotch
Please refer to the following table for detailed dual-channel DDR. Other
combination not listed below will function as single-channel DDR.
MSI Reminds You...
Dual-channel DDR works ONLY in the 3 combinations listed in
the table above.

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: ATX1
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.
ATX 12V Power Connector: JPW1
This 12V power connector is used to provide power to the CPU.
