4.4 Advanced Menu

CPU Speed [Manual]

When the motherboard is set to JumperFree

mode (see 3.4 Motherboard Settings), this field

allows you to select the internal speed of your

CPU. Available options include multiples of 66

and 100. Select [Manual] if you want to make

changes to the subsequent 2 fields. Note that

selecting a frequency higher than the CPU

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).
