CPU Ratio Selection:
This function allows user to adjust the CPU multiplier. The multiplier
is used to determine the internal clock speed of the processor relative
to the external clock speed. The number of clock ratio is depends on
the CPU installed.
Note
This function only works when an unlocked multiplier CPU is
used. A production Intel Pentium 4 processor is shipped with
multiplier locked.
CPU Host Clock (CPU/PCI,Mhz):
This function allows user to Auto or Manually adjust the CPU host
clock (FSB) from 100Mhz to 200Mhz by 1 Mhz increment. Available
options are: Auto / Semi-Auto.
The default setting is Auto .
Depending on the CPU used, a two stage FSB selection will be
automatically set. Use + / - key to increase / decrease the FSB speed by
1 Mhz increment.
Pentium 4 with 100Mhz FSB – 100~133Mhz
Pentium 4 with 133Mhz FSB – 133~200Mhz
A smart safety feature is employed in this mainboard to set the system
back to the CPU’s default setting after the OverClocking failed.
Note
CPU Frequency Set Up Procedure
CPU core speed = Host Clock x Core/Bus ratio
For example: 2.53GHz CPU is derived from:
CPU Clock 133MHz X Core/Bus ratio 19
= 133MHz X 19 = 2.53GHz
