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.

Selecting a frequency higher than the CPU manufacturer recommends may cause the system to hang or crash!

CPU Frequency Multiplier (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 allows you to set the frequency multiple between the CPU’s internal frequency (CPU speed) and external frequency.

CPU External Frequency (MHz) (when CPU Speed is set to [Manual])

This feature tells the clock generator which 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. The ratios that appear in the popup menu vary according to the CPU Frequency. The auto setting is recommended for normal use. Configuration options: [Auto] [3x] [4x]
