Advanced Menu
CPU Speed [Manual]
When the motherboard is set to JumperFree™ mode, this field allows you
to select the internal frequency of the CPU. Select [Manual] if you want to
make changes to the two subsequent fields. Note that selecting a
frequency higher than the CPU manufacturer recommends may cause the
system to hang or crash.
CPU Frequency Multiple (when CPU Speed is set to [Manual])
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. Set this field in conjunction with CPU Frequency
(MHz) to match the speed of the CPU.
CPU Frequency (MHz) (when CPU Speed is set to [Manual])
This feature tells the clock generator what frequency to send to the system
bus. The bus frequency (external frequency) multiplied by the bus multiple
equals the CPU speed.
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
Frequency (MHz). Configuration options: [Auto] [1:1] [3:4]
