Hardware Setup
This chapter provides you with the information about hardware
setup procedures. While doing the installation, be careful in holding the
components and follow the installation procedures. For some
components, if you install in the wrong orientation, the components will
not work properly.
Use a grounded wrist strap before handling computer
components. Static electricity may damage the components.

MS-7043 ATX Mainboard
Central Processing Unit: CPU
The mainboard supports Intel® Pentium® 4 processors 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 have 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 = 200MHz
Core/Bus ratio = 12
then CPU core speed = Host Clock x Core/Bus ratio
= 200MHz x 12
= 2.4 GHz
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 settings
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.

Hardware Setup
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 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 retention 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
Memory Population Rules
Install at least one DIMM module on the slots. Each DIMM slot supports up to a
maximum size of 1GB. You can install either single- or double-sided modules to meet
your own needs.
The PT880 Neo-V supports dual-channel mode and the PT8 Neo-V & PX8 NeoV support only single-channel mode. Users may install memory modules of different
types and density under single-channel mode. Under dual-channel mode, however,
please make sure that you install memory modules of the same type and density
on DDR DIMMs “in pairs” -- {DIMM1 & DIMM3} or {DIMM2 & DIMM3} to ensure
system stability.
The PT880 Neo-V provides 3 slots for 184-pin, 2.5V DDR DIMM and supports
up to 3GB memory size. You can install DDR266/DDR333/DDR400/DDR433/DDR466
SDRAM modules on the DDR DIMM slots (DIMM 1~3).
The PT8 Neo-V & PX8 Neo-V provide 2 slots for 184-pin, 2.5V DDR DIMM and
supports up to 2GB memory size. You can install DDR266 / DDR333 / DDR400 (for
PT8 Neo-V only) / DDR433 (for PT8 Neo-V only)/DDR466 (for PT8 Neo-V only)
SDRAM modules on the DDR DIMM slots (DIMM 1~2).
To operate properly, at least one DIMM module must be installed. Please note
that DDR433/DDR466 are overclocking specs for PT880 Neo-V/PT8 Neo-V
only.

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:
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.
PCI (Peripheral Component Interconnect) Slots
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.
Order 1 Order 2 Order 3 Order 4
PCI Slot 1 INT A# INT B# INT C# INT D#
PCI Slot 2 INT B# INT C# INT D# INT A#
PCI Slot 3 INT C# INT D# INT A# INT B#

Chapter 3. BIOS Setup
This chapter provides Frequency/Voltage Control information
on the BIOS Setup program and allows you to configure the system
for optimum use. You may need to run the Setup program when:
An error message appears on the screen during the system boot-
ing up, and requests you to run SETUP.
You want to change the default settings for customized features.
Upon boot-up, the 1st line appearing after the memory count is
the BIOS version. It is usually in the format:
A6380MS V1.0 091096 where:
1st digit refers to BIOS maker as A = AMI(R) W = AWARD(R).
2nd - 5th digit refers to the model number.
6th - 7th digit refers to the customer as MS = all standard customers.
V1.0 refers to the BIOS version.
091096 refers to the date this BIOS was released.

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
[Disabled] for optimal system stability and performance. But if you are plagued by EMI,
set to [Enabled] for EMI reduction. Remember to disable Spread Spectrum if you are
overclocking because even a slight jitter can introduce a temporary boost in clock
speed which may just cause your overclocked processor to lock up.
Stop Unused PCI Clock
This item enables or disables the PCI slot clock. Setting options: [Enabled], [Disabled].
Dynamic Overclocking
Dynamic Overclocking Technology is the automatic overclocking function, included in
the MSITM 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 that the 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 restore the
default settings instead. Usually the Dynamic Overclocking Technology will be powered
only when users' PC need to run huge amount of data like 3D games or the video
process, and the CPU frequency needs 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.
[Captain] 3rd level of overclocking, also the default value of "Load
High Performance Defaults".

MSI Reminds You...
The value plus a ratio (CPU: DDR) with parentheses means the nonsynchronous overclocking.
MSI Reminds You...
1. Even though the Dynamic Overclocking Technology is more stable
than manual overclocking, basically, it is still risky. We suggest
that users make sure that the CPU can afford to overclocking regularly first. If you find the PC appears to be unstable or reboot
incidentally, 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, there are two functions to protect user's system from
crashing.
- There is a safe key "Ins" in BIOS. In case the overclocking
fails, you can press "Ins" key while system rebooting to restore to the BIOS defaults.
- If the system incidentally reboot for four times, the BIOS will
also be restored to the defaults.

MSI Reminds You...
The settings shown in different color in CPU Voltage, DDR Voltage,
AGP Voltage, and North Bridge/South Bridge Voltage help to verify if
your setting is proper for your system.
White: Safe setting.
Yellow: High performance setting.
Red: Not recommended setting and the system may be unstable.
Changing CPU/DDR/AGP/North Bridge/South Bridge Voltage may re-
sult in the instability of the system; therefore, it is NOT recommended
to change the default settings for long-term usage.
CPU Voltage Adjust
The setting allows you to adjust the CPU Vcore voltage, which depends on the CPU.
AGP Voltage Adjust (V)
AGP voltage is adjustable in the field, allowing you to increase the performance of your
AGP display card when overclocking, but the stability may be affected.
DDR Voltage Adjust (V)
This setting is used to adjust the DRAM core voltage (Vcore), making overclocking
possible.
North Bridge/South Bridge Voltage (V)
These two items configure the voltage of the North Bridge and the South Bridge for
overclocking purposes.
