4.4 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
change 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 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.
The item CPU Frequency Multiple is accessible only if you have an
unlocked processor. If your processor frequency multiple is locked, you
cannot change the setting of this item.
CPU External Frequency (MHz)
(when CPU Speed is set to [Manual])
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.
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]
