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
comply with the emission limits.

Multiplier and FSB
ØVoltage allows user to adjust the voltage of CPU/Memory/AGP
ØMSI Info provides information about the mainboard, BIOS and OS
ØCPU Info provides detailed information about the CPU
ØCPU Fan Speed shows the current running speed of CPU Fan
ØCPU Temp. shows the current CPU temperature
FuzzyLogic™4
The Fuzzy Logic™ 4 utility is a user friendly tool that allows users to
view and adjust the current system status. To overclock the CPU FSB (Front
Side Bus) frequency under the Windows operating system, click FSB and use
the right and left arrow keys to select the desired FSB, and then click Apply to
apply the new setup value. To enable the system running at the specified FSB
every time when you click Turbo, click Save to save the desired FSB first. If
you want to know the maximal CPU overclocking value, click Auto to start
testing. The CPU FSB will automatically increase the testing value until the PC
reboots. After rebooting, click Turbo to apply the test result. Click Default to
restore the default values.
