8) CPU External Frequency Setting (DSW)

This option tells the clock generator what frequency to send to the CPU, DRAM,

and the PCI bus. This allows the selection of the CPU’s External frequency. The

CPU External Frequency multiplied by the Frequency Multiple equals the CPU’s

Internal frequency (the advertised CPU speed). NOTE: You may set the memory

speed independently from the CPU External Frequency. Depending on your

memory type, select the appropriate “SDRAM” speed along with the appropri-

ate “CPU” speed.

NOTE: For JumperFree mode, all dip switches (DSW) must be set to OFF.

NOTE: Frequency Multiple settings are not available here because usually Socket

370 processors have locked Frequency Multiples. If your processor does not

have a locked Frequency Multiple, you must use CPU Core:Bus Freq. Mul-

tiple in 4.4 Advanced Menu of the BIOS setup to set the Frequency Multiple. If

the Frequency Multiple is locked, setting the Frequency Multiple in BIOS setup

will have no effect.

WARNING! CPU frequencies above 66MHz exceed the specifications for cur-

rent Celeron processors and are not guaranteed to be stable. For Coppermine pro-

cessors, CPU frequencies other than the recommended bus frequencies are not

guaranteed to be stable. Premature wearing of the processor may result when

overclocking. Be sure that the DIMM you use can handle the specified SDRAM

MHz or else bootup will not be possible.
