FCC-A Radio Frequency Interference Statement
This equipment has been tested and found to comply with the limits for a class
A digital device, pursuant to part 15 of the FCC rules. These limits are designed
to provide reasonable protection against harmful interference when the equip-
ment is operated in a commercial environment. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in accor-
dance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to
cause harmful interference, in which case the user will be required to correct
the interference at his own expense.
Notice 1
The changes or modifications not expressly approved by the party respon-
sible for compliance could void the user’s authority to operate the equipment.
Notice 2
Shielded interface cables and A.C. power cord, if any, must be used in order to
comply with the emission limits.

Setup
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.

2-2
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 CPUClock = 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-de-
gree 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, al-
ways close the lever with your
fingers pressing tightly on top of
the CPU to make sure the CPU is
properly and completely embed-
ded into the socket.

5. Connect the fan power cable from
the mounted fan to the 3-pin fan
power connector on the board.
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 re-
tention mechanism.
4. Press the two levers down to fasten
the fan. Each lever can be pressed
down in only ONE direction.

Hardware Setup
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 Neo-
V 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.
