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.

Replacing the CPU

While replacing the CPU, always turn off the ATX power supply or
unplug the power supply’s power cord from grounded outlet first to
ensure the safety of CPU.

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.

CPU & Cooler Installation

When you are installing the CPU, make sure the CPU has a cooler at-

tached 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 heat sink/cooler fan for better heat dispersion.

Follow the steps below to install the CPU & cooler correctly. Wrong installation

will cause the damage of 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 right­bottom corner.

2. T ake out the accompanying CPU Clip
and rotate it for the same direction
as the CPU (Pin 1 indicator, the red
triangle is in the left-bottom corner).

3. Align the 3 points (the Pin 1 indicator
and the two alignment keys) of both
the CPU and the CPU Clip, and use your
4 fingers to push the CPU Clip down to
clip them (the CPU clip is up and the
CPU is down) together.

4. The land side cover now is
removed.

land side cover

MSI Reminds You...

1. Confirm if your CPU cooler is firmly installed before turning on your
system.

2. Do not touch the CPU socket pins to avoid damaging.

3. The availability of the CPU land side cover depends on your CPU
packing.

E-2-5

Hardware Setup

5. The CPU 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
(as the arrow shows).

7. The pins of socket reveal. Then lift
up the load lever.

8. Lift the load lever up and open the
load plate.

9. Correctly align the red triangle of
CPU clip with the CPU chamfer, the
red arrow with the left-side socket
edge, and the red spot to the hook
of the socket.

10.Put the whole module onto the CPU
socket.

E-2-6

MS-6728 ATX Mainboard

11.Push down the CPU hard to install
the CPU into the socket housing
frame.

12.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.

13. Press down the load lever lightly
onto the load plate, and then se­cure the lever with the hook under
retention tab.

14. 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.

16. Turn over the mainboard to confirm

that the clip-ends are correctly
inserted.

15. 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.

MSI Reminds You...

1.Check the information in PC Health Status in BIOS (refer to p.3-25 for
details) for the CPU temperature.

2. Whenever CPU is not installed, always protect your CPU socket pin
with the plastic cap covered (shown in Figure 1) to avoid damaging.

3. 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.

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.

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.

E-2-8

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.

Connectors

FDD1

Fan Power Connectors: CPUFAN1/SF AN1/SF AN2/NBF AN1

The CPUFAN1 (processor fan), SFAN1/SFAN2 (system fans) and NBFAN1
(NorthBridge Chipset fan) support system cooling fan with +12V. It supports four/
three-pin head connector. When connecting the wire to the connectors, always take
note that the red wire is the positive and should be connected to the +12V, the black
wire is Ground and should be connected to GND. If the mainboard has a System
Hardware Monitor chipset on-board, you must use a specially designed fan with
speed sensor to take advantage of the CPU fan control.

MS-6728 ATX Mainboard

A T A100 Hard Disk Connectors: IDE1 & IDE2

The mainboard has a 32-bit Enhanced PCI IDE and Ultra DMA 66/100 controller
that provides PIO mode 0~4, Bus Master, and Ultra DMA 66/100 function. You can
connect up to four hard disk drives, CD-ROM and other IDE devices.

The Ultra ATA100 interface boosts data transfer rates between the computer
and the hard drive up to 100 megabytes (MB) per second. The new interface is one­third faster than earlier record-breaking Ultra ATA/100 technology and is backward
compatible with the existing Ultra ATA interface.

IDE1 (Primary IDE Connector)
The first hard drive should always be connected to IDE1. IDE1 can connect a Master

and a Slave drive. You must configure second hard drive to Slave mode by setting the
jumper accordingly.

IDE2 (Secondary IDE Connector)
IDE2 can also connect a Master and a Slave drive.

MSI Reminds You...

If you install two hard disks on 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.
