Available options in- clude multiples of 100 and 133. Select [Manual] if you want to make changes to the subsequent 2 fields.

BIOS SETUP Multiples of 133 (for 133MHz FSB) CPU : System Frequency Multiple (when CPU Speed is set to [Manual]) This field is for unlocked processors only.
If your processor’s Frequency Multiple is detected locked, you will not be able to access this field. This field sets the frequency multiple between the CPU’s internal frequency and external frequency. This must be set in conjunction with System/PCI Fre- quency (MHz) to match the speed of your CPU. Configuration options: [2.0x] [2.5x] [3.0x]...[7.0x] [7.5x] [8.0x] System/PCI 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 (the CPU’s internal frequency). ASUS CUV4X-M User’s Manual 56
