4.4 Advanced Menu

CPU Speed [Manual]
When the motherboard is set to JumperFree
mode (see 3.4 Motherboard Settings), this field
Multiples of 66
allows you to select the internal speed of your
(for a 66MHz FSB)
CPU. Available options include multiples of 66
and 100. Select [Manual] if you want to make
changes to the subsequent 2 fields. Note that
Multiples of 100
selecting a frequency higher than the CPU (for a 100MHz FSB)
manufacturer recommends may cause the sys-
tem to hang or crash. See System Hangup on
page 57.
CPU Core:Bus Freq. Multiple (when CPU Speed is set to [Manual])
This field sets the frequency multiple between the CPU's internal frequency
and external frequency. This must be set in conjunction with CPU Bus Fre-
quency to match the speed of your CPU. Configuration options: [2.0x] [2.5x]
[3.0x]...[7.0x] [7.5x] [8.0x]
CPU Bus/PCI Freq. (MHz) (when CPU Speed is set to [Manual])
This feature tells the clock generator what frequencies to send to the local
bus and PCI devices onboard. The bus frequency (external frequency) mul-
tiplied by the bus multiple equals the CPU's internal frequency (the CPU
speed).
