CPU Core Speed Derivation Procedure

If CPU Clock = 100MHz

Core/Bus ratio = 20

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

= 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 pur­chase and install them before turning on the computer.

(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. Y ou can install DDR266 / DDR333 / DDR400 / DDR433 / DDR466
/ DDR500 / DDR533 SDRAM modules on the DDR DIMM slots (DIMM 1~4).
T o 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 Mod­ules” 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.

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.

MSI Reminds Y ou...

You can barely see the golden finger if the module is properly
inserted in the socket.

PCI Interrupt Request Routing

The IRQ, acronym of interrupt request line and pronounced I-R-Q, are
hardware lines over which devices can send interrupt signals to the
microprocessor. The PCI IRQ pins are typically connected to the PCI bus INT
A# ~ INT D# pins as follows:

Slots

AGP (Accelerated Graphics Port) Slot

The AGP slot allows you to insert the AGP graphics card. AGP is an
interface specification designed for the throughput demands of 3D graphics.
It introduces a 66MHz, 32-bit channel for the graphics controller to directly
access main memory. The slot supports 8x/4x AGP card.

The PCI slots allow you to insert the expansion cards to meet your needs.
When adding or removing expansion cards, make sure that you unplug the
power supply first. Meanwhile, read the documentation for the expansion card
to make any necessary hardware or software settings for the expansion card,
such as jumpers, switches or BIOS configuration.

The mainboard provides one AGP slot and five 32-bit PCI bus slots.

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, refreshing
may be incomplete and DRAM may fail to retain data. This item
applies only when synchronous DRAM is inst alled in the system.
Available settings: 2 clocks, 3 clocks, 4 clocks.

RAS# to CAS# Delay

When DRAM is refreshed, both rows and columns a re 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, .

delay for DRAM precharge. Settings: 5 clocks, 6 clocks, 7 clocks, 8
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.

AGP Aperture Size (MB)

This setting controls just how much system RAM can be allocated to AGP for
video purposes. The aperture is a portion of the PCI memory address range
dedicated to graphics memory address space. Host cycles that hit the aperture
range are forwarded to the AGP without any translation. The option allows the
selection of an aperture size of 4MB, 8MB, 16MB, 32MB, 64MB, 128MB, and

256 MB.

1. Even though MAT is easy to use, it doesn't mean there's no
risk at all . We recommend you to check if your memory is
able to bear MAT setting or not before deciding to always
use it. If your system will be unstable or reboot incidentally
afte r switching to Fast, ple ase switch back to Normal.
Moreover, if you want to conduct FSB overclock ing, you

D.O.T. Range

(D.O.T) Dynamic Overclocking Technology is the automatic overclocking
function, included in the MSITM’s newly developed CoreCell

TM

Technology. It
is designed to detect the load balance of CPU while running programs, and to
adjust the best CPU frequency automatically. When the motherboard detects
CPU is running programs, it will speed up CPU automatically to make the
program run smoothly and faster. When the CPU is temporarily suspending or
staying in the low load balance, it will rest ore the default settings i nstead.
Usually the Dynamic Overclocking Technology will be pow ered only when
users' PC need to run huge amount of data like 3D games or the video process,
and the CPU frequency need to be boosted up to enhance the overall
performance. Setting options:

Disabled Disable Dynamic Overclocking.
Private 1st level of overclocking.
Sergeant 2nd level of overclocking.
Captai n 3rd level of overclocking, also the default value of "Load

High Performance Defaults".

Colonel 4th level of overclocking.
General 5th level of overclocking.
Commander 6th level of overclocking.

MSI Reminds You...

Even t hough the Dynamic Overcl ocking Technol ogy is more
stable than manual overclocking, basically, it is still risky. We
suggest use r to make sure that your CPU can af ford to
overclocking regularly first. If you find the PC appears to be
unstable or reboot inc identally, it's better to disable the Dy­namic Overclocking or to lower the level of overclocking options.
By the way, if you need to conduct overclocking manually, you
also need to disable the Dynamic OverClocking first.

2. Meanwhile, for security reason, the re are two functions to
protect BIOS and pr otect user’s system from crashing:
(a)There is a safe hotkey "Ins" in BIOS. If the overclocking

or/and MAT fails to run, you can press "Ins" key while
rebooting system to restore to the BIOS Defaults.

(b) If your system reboot for four times continually, the BIOS

will be restored to the Defaults (Normal), too

Spread Spectrum

When the motherboard’s clock generator pulses, the extreme values (spikes)
of the pulses creates EMI (Electromagnetic Interference). The Spread Spec­trum function reduces the EMI generated by modulating the pulses so that the
spikes of the pulses are reduced to flatter curves. If you do not have any EMI
problem , leave the setting at Di sabled for opt ima l system sta bility and
performance. But if you are plagued by EMI, activate the Spread Spectrum for
EMI reduction. Remember to disable Spread Spectrum if you are overclocking
because even a slight jitt er can introduce a temporary boost in clock speed
which may just cause your overclocked processor to lock up. Options: Disabled,
