3.1.8.4 CPU Frequency
This field provides several options for selecting the external system
bus clock of the processor.
Important:
Overclocking may result in the processor’s or system’s instability
and is not guaranteed to provide better system performance.
If, in the “CPU Clock Ratio” or “CPU Frequency” field, you selected
an option other than the default setting and is unable to boot up
the system, there are 2 methods of booting up the system and
going back to its default setting.
Method 1:
Clear the CMOS data by setting JP2 to 1-2 On. All fields in the
BIOS Setup will automatically be set to their default settings.
Method 2:
Press the <Insert> key and power button simultaneously, then re-
lease the power button first. Keep-on pressing the <Insert> key until
the power-on screen appears. This will allow the system to boot
according to the FSB of the processor. Now press the <Del> key
to enter the main menu of the BIOS. Select “Frequency/Voltage Con-
trol” and set the “CPU Clock Ratio” or “CPU Frequency” field to its
default setting or an appropriate bus clock.
Note:
Use a PS/2 or AT (requires a DIN to mini DIN adapter) key-
board for method 2.
3.1.8.5 CPU:DRAM Frequency Ratio
This field is used to select the ratio between the CPU and DRAM
clocks.
3.1.8.6 DRAM Frequency
This field shows the detected frequency of the DDR SDRAM DIMM.
