BIOS Setup
3.1.8.3 FSB Frequency
This field provides several options for selecting the FSB of the CPU.
The available options allow you to adjust the CPU’s bus clock by
1MHz increment.
Important:
Selecting a bus frequency other than the default setting may
result to the CPU’s or system’s instability and are not
guaranteed to provide better system performance.
3.1.8.4 CPU Ratio
This field is used to select the frequency ratio of the processor.
Important:
The frequency ratio of some processors may have been locked
by the manufacturer. If you are using this kind of processor,
setting an extended ratio for the processor will have no effect.
The system will instead use its factory default ratio.
3.1.8.5 CPU Interface
This field is used to configure the CPU’s interface.
Optimal
Uses the most stable CPU/FSB parameters.
Aggressive
Uses the overclock CPU/FSB parameters.
3.1.8.6 Memory Frequency
Auto
The system will automatically detect the frequency of
the DIMM.
By SPD
The EEPROM on a DIMM has SPD (Serial Presence
Detect) data structure that stores information about
the module such as the memory type, memory size,
memory speed, etc. When this option is selected, the
system will run according to the information in the
EEPROM. This option is the default setting because it
provides the most stable condition for the system.
3.1.8.7 Resulting Frequency
This field will show the current frequency of the DIMM.
