Hardware Setup

Central Processing Unit: CPU

The mainboard supports Intel® Pentium® 4 Northwood/Prescott processor

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 purchase
and install them before turning on the computer.

CPU Core Speed Derivation Procedure

If CPU Clock = 100MHz

Core/Bus ratio = 16

then CPU core speed = Host Clock x Core/Bus ratio

= 100MHz x 16
= 1.6 GHz

MSI Reminds Y ou...

Overheating

Overheating will seriously damage the CPU and system, always
make sure the cooling fan can work properly to protect the CPU
from overheating.

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.

Open Lever

2. Pull the lever sideways away

from the socket. Make sure
to raise the lever up to a 90­degree angle.

3. Look for the gold arrow. The
gold arrow should point to­wards 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
procedures 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

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-

2-7

MS-6728 ATX Mainboard

channelDDR DIMMs. However, the same type and density memory modules
are necessary while using dual-channel DDR, or instability may happen.

Please refer to the following table for detailed dual-channel DDR. Other
combination not listed below will function as single-channel DDR.

DIMM1 (Ch A) DIMM2 (Ch A) DIMM3 (Ch B) DIMM4 (Ch B) System Density
128MB~1GB 128MB~1GB 256MB~2GB

128MB~1GB 128MB~1GB 128MB~1GB 128MB~1GB 512MB~4GB

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.

3-13

MS-6728 ATX Mainboard

CAS# Latency

This controls the timing delay (in clock cycles) before SDRAM starts
a read command after receiving it. Settings: 2, 2.5 (clocks). 2 (clocks)
increases the system performance the most while 2.5 (clocks) provides
the most stable performance.

RAS# Precharge

This item controls the number of cycles for Row Address Strobe
(RAS) to be allowed to precharge. If insufficient time is allowed for
the RAS to accumulate its charge before DRAM refresh, refresh may
be incomplete and DRAM may fail to retain data. This item applies
only when synchronous DRAM is installed in the system. A vailable
settings: 2 clocks, 3 clocks, 4 clocks.

RAS# to CAS# Delay

When DRAM is refreshed, both rows and columns are addressed
separately. This setup item allows you to determine the timing of the
transition from RAS (row address strobe) to CAS (column address
strobe). The less the clock cycles, the faster the DRAM performance.
Setting options: 2 clocks, 3 clocks, 4 clocks, .

Burst Length

This setting allows you to set the size of Burst-Length for DRAM.
Bursting feature is a technique that DRAM itself predicts the address
of the next memory location to be accessed after the first address is
accessed. To use the feature, you need to define the burst length,
which is the actual length of burst plus the starting address and
allows internal address counter to properly generate the next memory
location. The bigger the size, the faster the DRAM performance.
Available settings: 4, 8.

Power Management Features

MSI Reminds Y ou...

S3-related functions described in this section are available only
when your BIOS supports S3 sleep mode.

ACPI Standby State

This item specifies the power saving modes for ACPI function. If your operating
system supports ACPI, such as Windows 98SE, Windows ME and Windows
2000, you can choose to enter the Standby mode in S1(POS) or S3(STR) fashion
through the setting of this field. Options are:

S1/POS The S1 sleep mode is a low power state. In this state, no

system context is lost (CPU or chipset) and hardware
maintains all system context.

S3/STR The S3 sleep mode is a lower power state where the in

formation of system configuration and open applications/
files is saved to main memory that remains powered
while most other hardware components turn off to save
energy. The information stored in memory will be used
to restore the system when a “wake up” event occurs.

Auto BIOS determines the best mode automatically.

BIOS Setup

Re-Call VGA BIOS at S3 Resuming

Selecting Enabled allows BIOS to call VGA BIOS to initialize the VGA card
when system wakes up (resumes) from S3 sleep state. The system resume time
is shortened when you disable the function, but system will need an AGP
driver to initialize the VGA card. Therefore, if the AGP driver of the card
does not support the initialization feature, the display may work abnormally
or not function after resuming from S3.

PNP/PCI Configurations

This section describes configuring the PCI bus system and PnP (Plug

& Play) feature. PCI, or Peripheral Component Interconnect, is a system which
allows I/O devices to operate at speeds nearing the speed the CPU itself uses
when communicating with its special components. This section covers some
very technical items and it is strongly recommended that only experienced
users should make any changes to the default settings.

Clear NVRAM

The ESCD (Extended System Configuration Data) NVRAM (Non-volatile
Random Access Memory) is where the BIOS stores resource information for
both PNP and non-PNP devices in a bit string format. When the item is set to
Yes, the system will reset ESCD NVRAM right after the system is booted up
and then set the setting of the item back to No automatically.

PCI Latency Timer (PCI Clocks)

This item controls how long each PCI device can hold the bus before another
takes over. When set to higher values, every PCI device can conduct
transactions for a longer time and thus improve the effective PCI bandwidth.
For better PCI performance, you should set the item to higher values. Settings
range from 32 to 248 at a 32 increment.

3-21

MS-6728 ATX Mainboard

IRQ 3/4/5/7/9/10/11/14/15

These items specify the bus where the specified IRQ line is used.
The settings determine if AMIBIOS should remove an IRQ from the pool
of available IRQs passed to devices that are configurable by the system
BIOS. The available IRQ pool is determined by reading the ESCD NVRAM.
If more IRQs must be removed from the IRQ pool, the end user can use
these settings to reserve the IRQ by assigning an ISA/EISA setting to it.
Onboard I/O is configured by AMIBIOS. All IRQs used by onboard I/O
are configured as PCI/PnP. If all IRQs are set to ISA/EISA, and IRQ 14/15
are allocated to the onboard PCI IDE, IRQ 9 will still be available for PCI
and PnP devices. Available settings: ISA/EISA and PCI/PnP.

Set DMAs to PnP or ISA

Press <Enter> to enter the sub-menu and the following screen appears:

DMA Channel 0/1/3/5/6/7

These items specify the bus that the system DMA (Direct Memory
Access) channel is used.
The settings determine if AMIBIOS should remove a DMA from the
available DMAs passed to devices that are configurable by the system
BIOS. The available DMA pool is determined by reading the ESCD
NVRAM. If more DMAs must be removed from the pool, the end user can
reserve the DMA by assigning an ISA/EISA setting to it.

Hardware Configuration

After installing the audio driver, you are able to use the 4-/6-channel
audio feature now. To enable 4- or 6-channel audio operation, first connect 4 or
6 speakers to the appropriate audio connectors, and then select 4- or 6-channel
audio setting in the software utility.

There are two ways to utilize the function and connect the speakers to
your computer:

! Use the optional S-Bracket. If your motherboard supports S-Bracket

and you have installed S-Bracket in the computer, you can connect
two speakers to back panel’s Line-Out connector, and the rest of
speakers to S-Bracket.

! Use the back panel only (without S-Bracket). If you do not have

a S-Bracket, you can connect all speakers to the audio connectors
on the back panel.

After installing the C-Media drivers, you can attach the speakers for 4­/6-channel audio output. Always connect the speakers to the LINE OUT
connectors. Different connector configurations for 2-/4-/6-channel operations

volume level of digital audio, you can enable Loudness (AGC). It provides
extra +3dB to +12dB gain to all channels. The driver has also been designed
with a sophisticated auto gain control minimizing the signal clipping
distortion. However, it is not recommended to
