CPU Clock Ratio
This setup option will automatically assign by CPU detection.
The option will display "Locked" and read only if the CPU ratio is not changeable.
Memory Frequency For
Wrong frequency may make system can't boot, clear CMOS to overcome wrong frequency issue.
for FSB(Front Side Bus) frequency=533MHz,
3.0 Memory Frequency = Host clock X 3.0.
4.0 Memory Frequency = Host clock X 4.0.
Auto Set Memory frequency by DRAM SPD data. (Default value)
for FSB(Front Side Bus) frequency=800MHz,
2.0 Memory Frequency = Host clock X 2.0.
2.66 Memory Frequency = Host clock X 2.66.
Auto Set Memory frequency by DRAM SPD data. (Default value)
Memory Frequency (Mhz)
The values depend on "Memory Frequency For" item.
Incorrect using these features may cause your system broken. For power end-user use only.

CPU Smart FAN Mode
This option is available only when CPU Smart FAN Control is enabled.
Auto BIOS autodetects the type of CPU fan you installed and sets the optimal CPU
Smart FAN control mode for it. (Default Value)
Voltage Set to Voltage when you use a CPU fan with a 3-pin fan power cable.
PWM Set to PWM when you use a CPU fan with a 4-pin fan power cable.
Note: In fact, the Voltage option can be used for CPU fans with 3-pin or 4-pin power cables.
However, some 4-pin CPU fan power cables are not designed following Intel 4-Wire fans PWM
control specifications. With such CPU fans, selecting PWM will not effectively reduce the fan
speed.
