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

The mainboard supports Intel® Pentium® 4 Northwood 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.

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.

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.

The relation between CPU FSB and memory SPD

On this 655Max mainboard, the CPU FSB controls the SPD of memory. When
the CPU FSB is 400MHz or 533 MHz, you may use DDR200, DDR 266 or
DDR 333 for your memory.

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 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
tightly on top of the CPU to
make sure the CPU is
properly and completely
embedded into the socket.

Installing the CPU Fan

As processor technology pushes to faster speeds and higher performance,
thermal management becomes increasingly important. To dissipate 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 motherboard.

3. Mount the fan on top of the heatsink.

Press down the fan until its four clips
get wedged in the holes of the reten­tion mechanism.

4. Press the two levers down to fasten

the fan. Each lever can be pressed
down in only ONE direction.

Memory

The mainboard provides 4 slots for 184-pin, 2.5V DDR DIMM with 8
memory banks. You can install DDR200/PC1600, DDR266/PC2100 or
DDR333/PC2700 DDR SDRAM modules on the DDR DIMM slots (DIMM
1~4). To operate properly, at least one DIMM module must be installed.

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. High memory
bandwidth makes DDR an ideal solution for high performance PC, worksta­tions and servers.

2-8

MS-6730 ATX Mainboard

Installing DDR Modules

1. The DDR DIMM has only one notch on the center of module. The mod-

ule 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.

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 ESCD

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

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/
EISAsetting 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.

When you select Optimal Performance Defaults, a message as below
appears:

Pressing ‘Enter’ loads the default values that are factory settings for
stable system performance.

When you select Load High Performance Defaults, a message as below
appears:

Pressing ‘Enter’ loads the default values that enable the best system
performance but may lead to a stability issue.

MSI Reminds Y ou...

The option is for power or overclocking users only. Use of high
performance defaults will tighten most timings to increase the
system performance. Therefore, a high-end system configuration
is a must, which means you need high-quality VGA adapter,
RAM and so on. We don’t recommend that users should apply

the high performance defaults in their regular systems.

Otherwise, the system may become unstable or even crash. If the
system crashes or hangs after enabling the feature, please CLEAR

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
