CPU0 / CPU1 Speed

This field displays the frequency of the central processors, CPU0 and CPU1.

Operating Frequency Setting [Manually]

This motherboard is preset for making frequency configurations “By Jumper,” ie.: using DSW switches and jumpers. When the motherboard JEN jumper is reset to enable JumperFree™ mode, then this field allows you to configure the speed of the central processor. The default, [Manually], allows for jumper/DSW FSB frequency settings; if two unlocked CPUs are installed, changing the setting sets the external frequency of both CPUs. Configuration options: [Manually] [Various MHz]

Set System Operation Frequency (when Operating Frequency Setting is set to [Default])

When the Operating Frequency Setting is set to [Manually], this field configures the external frequency of the CPU. Select [Manually] to make changes to the CPU Frequency field. If [950 MHz] is selected, the FSB Frequency will be fixed at 100MHz, and if [1266 MHz] is selected, then the FSB Frequency will be fixed at 133MHz. Configuration options: [Default] [-1 MHz] [+1 MHz]

FSB Frequency [100MHz] (Display only)

This field displays the 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). If a faster Operating Frequency is selected, the FSB automatically increases. Selecting frequencies higher than recommended for the processor may cause the system to hang or crash. Display options: [100 MHz] [133 MHz]
