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.
Select [Manual] if you want to make changes to the subsequent four fields.
Configuration options: [Manual] [266MHz] [300MHz] [333MHz] [366MHz]
[400MHz] [433MHz] [466MHz]
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).
CPU Vcore
This field displays the core voltage supplied to the CPU. If you want to
set it manually, always refer to the CPU documentation for the reason-
able voltage range.
