ØMSI Logo links to the MSI Web site
ØCPU Speed allows users to adjust the CPU speed through CPU
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
Fuzzy Logic™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.

CPU Thermal Protection
Aimed to prevent the CPU from overheating, MSI has developed a CPU
Thermal Protection mechanism for AMD Athlon™ XP 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 AMD Athlon™ XP CPU only.
