FCC-B Radio Frequency Interference Statement
This equipment has been tested and found to comply with the limits for a class
B 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

Core Center
The Core Center is a new utility you can find in the CD-ROM disk. The
utility 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 sub-
menus 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.

Getting Started
Left-side: Current system status
In the left sub-menu, you can configure the settings of FSB, Vcore,
Memory Voltage and AGP Voltage 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-side:PChardwarestatus during realtimeoperation
In the right sub-menu, here 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 click “OK” to apply the changes. The
values you set for the temperatures are the maximum thresholds for the system
for warnings, and the valus for fan speeds are the minimum thresholds.
Top-side:Usermode/Automode
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.

CPUThermalProtection
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.
