CPU Speed
This parameter displays the auto-detected CPU speed.
CPU Frequency Multiple
This field is for unlocked processors only. If your processor frequency
multiple is locked, you cannot access this field. This field sets the
frequency multiple between the CPU’s
internal frequency (CPU speed)
and external frequency.
CPU/PCI Frequency (MHz)
This feature tells the clock generator what frequency to send to the system
bus and PCI bus. The bus frequency (external frequency) multiplied by the
bus multiple equals the CPU speed. The setting of this field depends on
the CPU Frequency Multiple.
CPU/Memory Frequency Ratio [Auto]
This field determines whether the memory clock frequency is set to be in
synchronous or asynchronous mode with respect to the system frequency.
The options that appear in the popup menu vary according to the CPU/PCI
Frequency (MHz). Configuration options: [Auto] [1:1] [3:4]
CPU Level 1 Cache, CPU Level 2 Cache [Enabled]
These fields allow you to choose from the default of [Enabled] or choose
[Disabled] to turn on or off the CPU Level 1 and Level 2 built-in cache.
