CoreCenter
(TM)
- contains OC Menu panel, users can determine their
processor and memory type to optimize its memory capacity. This all-in-one
hardware console is advanced combination of the popular PC Alert and Fuzzy
Logic. Including powerful function with hardware monitor, system alert and
instinctive UI of overclocking, CoreCenter is just like your PC doctor that can
detect, view and adjust the PC hardware and system status during real time
operation.
In the left side it shows the current system status including the Vcore, 3.
3V, +5V and 12V. In the right side it shows the current PC hardware status such
as the CPU & system temperatures and all fans speeds.
When you click the red triangles in the left and right sides, two submenus will open for users to overclock, overspec or to adjust the thresholds of
system to send out the warning messages. If you click the Core Center button
in the top, a screen pops up for you to choose the “Auto mode” or “User
mode” of CPU fan.

Left-wing: Current system status
In the left sub-menu, you can configure the settings of FSB, Vcore,
Memory Voltage and AGP V oltage by clicking the radio button in front of each
item and make it available (the radio button will be lighted as yellow when
selected), use the “+” and “-” buttons to adjust, then click “OK” to apply the
changes. Then you can click Save to save the desired FSB you just configured.
Also you may click Auto to start testing the maximal CPU overclocking
value, The CPU FSB will automatically increase the testing value until the PC
reboots. Or you may click Default to restore the default values.
Right-wing: PC hardware status during real time operation
In the right sub-menu, you can configure the PC hardware status such as
CPU & system temperatures and fan speeds. You may use the scroll bars to
adjust each item, then click “OK” to apply the changes. The values you set for
the temperatures are the maximum thresholds for the system for warnings, and
the value for fan speeds are the minimum thresholds.
T op-side: User mode/Auto mode
Here you may adjust the CPU fan speed. If you choose User mode, you
may adjust the CPU fan speed in 8 different modes, from Stop to Full speed.
OC Menu
The exclusive OC Menu is fully developed to support DDR400+ memory
modules. By comprehensive validation
of over 67 DDR400+ memory modules,
MSI concluded best parameters for
DRAM voltage, Vio and other BIOS
settings. You can select DDR433,
DDR450, DDR466 and DDR500 from
DRAM frequency in BIOS setting. Or
you can just click on OC Menu button
to configure in the OC Menu at
CoreCenter. OC Menu will adjust the
necessary parameters of voltage and frequency simultaneously. The only limitation was the margin of processor from overclocking.

CPU Thermal Protection
Aimed to prevent the CPU from overheating, MSI has developed a CPU
Thermal Protection mechanism for Intel® CPU platform. This CPU Thermal
Protection mechanism works on a thermal signal sensor. If the mechanism
senses an abnormal temperature rise, it will automatically shut down the system
and the CPU temperature will then drop down and resume normal. With this
unique feature, users can better protect their CPU. Please note that this feature
is for Intel® Pentium CPU only.

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
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.
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.

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.

DIMM1-2
The mainboard provides 2 slots for 184-pin, 2.5V DDR DIMM modules
and supports the memory size up to 2 GB without ECC,. Y ou can install DDR266/
DDR333/DDR400 DDR SDRAM modules on the DDR DIMM slots. T o 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. Three types of
DDR are available at the time of writing: DDR266, DDR333 & DDR400. DDR266
DDR SDRAM running at 133MHz will produce about 1.6GB/s memory
bandwidth. DDR333 running at 166MHz will produce 2.1GB/s memory
bandwidth. DDR400 is also available with bandwidith up to 3.2GB/s for singlechannel mode or with 6.4GB/s for dual-channel mode. High memory bandwidth makes DDR an ideal solution for high performance PC, workstations and
servers.
