6.4Advanced 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 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.
