(C) JP5, JP6, JP7, JP8:
CPU Clock Ratio Selection (
optional
)
JP5 JP6, JP7 and JP8 is designed on the mainboard to select the CPU clock ratio.
Basically, the CPU clock ratio can be selected in the BIOS setup program,. So you
may find these jumpers are not presented on the board, When these jumpers are
installed on the mainboard, you have to "Disable" the "Processor Core Frequency"
in BIOS setup program before you can use these jumper settings to select the CPU
clock ratio. (
Note: the setting in the system BIOS has the higher priority than
the jumper setting.
