Fox Intelligent Overclock
► FSB - Memory Clock Mode
[Auto] - Set FSB and memory speed automatically.
[Linked] - Enter FSB speed manually. Memory speed will change proportionally.
[Unlinked] - Enter FSB speed and memory speed separately and manually.
► FSB - Memory Ratio
When “FSB - Memory Clock Mode” is set to “Linked”, this item is used to set up the ratio
between FSB and Memory.
► FSB (QDR), MHz
When “FSB - Memory Clock Mode” is set to “Linked” or “Unlinked”, you can set up the FSB
speed manually.
► MEM (DDR), MHz
When “FSB - Memory Clock Mode” is set to “Linked”, memory speed will proportionally
change. When “FSB - Memory Clock Mode” is set to “Unlinked”, you can set the memory
speed manually.
► CPU Clock Ratio Unlock
This item is used to enable or disable CPU clock ratio unlock function.
► CPU N/2 Ratio
This option will be displayed only if your CPU supports this feature. The speed of Front Side
Bus is in a transit from 266MHz to 333MHz, if we are still using integer multiplier in our
circuit design, the speed interval between two CPUs will be in a 333MHz step and only few
CPU models can be produced. The newly coming 45nm CPUs are supporting 0.5 multiplier
ratio to provide more flexible choices for CPUs. For example, 333MHz*7.0 = 2.33GHz,
333MHz*7.5 = 2.50GHz, while 333MHz*8.0 = 2.66GHz.
► CPU Spread Spectrum
If you enabled this function, it can significantly reduce the EMI (Electromagnetic Interference)
generated by the CPU, so to comply with FCC regulation. But if overclocking is activated, you
had better disable it.
