P6F104 User’s Manual
6. CPU Overclock Selection (JP24)
This jumper allows user to over CPU
Front Side Bus (FSB) clock from
66MHz bus to 100MHz bus speed.
2.2.5 Set CPU Speed in the CMOS Setup
The Soft-Menu (jumperless) design of the P6F104 allows the user
to set CPU Bus Clock and CPU core to Bus clock multiplier
through the BIOS. However Intel’s Celeron CPU lock CPU Bus
clock and CPU core to bus clock multiplier so most of the case you
do not have to set these two options at all. You can just plug in the
CPU and let mainboard take care all the settingt for you.
CPU Bus Clock:
The CPU Bus Clock is defined as the CPU input
clock.
CPU Core to Bus Clock Multiplier:
The CPU internal core clock
is equal to the “CPU Bus Clock” times the “CPU Core to Bus Clock
Multiplier”. For example, if the CPU Bus Clock is 66.6MHz and
the CPU Core to Bus clock Multiplier is 5.5, the actual CPU core
clock will be 366MHz.
CPU Voltage:
There is no hardware or BIOS settings needed for
CPU operating voltage. The switching regulator circuit can auto-
detect the CPU type on the P6F104 mainboard and generate the
proper operating voltage for the CPU.
