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 CPUs External frequency. The
CPU External Frequency multiplied by the Frequency Multiple equals the CPUs
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.
