Frequency/Voltage Control
ø
This allows user to configure CPU frequency and voltage settings.
n CPU Clock Ratio
Allows user to set the CPU Clock Ratio.
If the CPU used locks this feature, then it will not be displayed or will not function. (based
on CPU type)
n Memory Frequency For
for FSB(Front Side Bus) frequency=533MHz,
2.50
Memory Frequency = Host clock X 2.50.
3.00
Memory Frequency = Host clock X 3.00.
4.00
Memory Frequency = Host clock X 4.00.
Auto
Set Memory frequency by DRAM SPD data.
for FSB(Front Side Bus) frequency=800MHz,
1.66
Memory Frequency = Host clock X 1.66.
2.00
Memory Frequency = Host clock X 2.00.
2.66
Memory Frequency = Host clock X 2.66.
Auto
Set Memory frequency by DRAM SPD data.
n Memory Frequency (Mhz)
The memory frequency is based on the " Memory Frequency For" setting.
Options:
Auto (BIOS autochecks which type of CPU fan is installed and sets the
optimcal CPU Smart FAN control mode.)
Voltage (Set this item to Voltage if a 3-pin CPU fan is installed.)
PWM (Set this item to PWM if a 4-pin CPU fan is installed.)
Note:
In fact, you can set the CPU Smart Fan Control mode to Voltage for either 3-
pin or 4-pin CPU fan. However, for those 4-pin CPU fans that are not
designed following Intel's 4-wire fans PWM control specifications, setting
the CPU Smart Fan Control mode to PWM may not effectively reduce the CPU
fan speed.
