More detailed descriptions of FIS feature can be found in FOX One utility of Chapter 4.
The following 5 settings are valid only when the Fox Intelligent Stepping is set to [Manual].
► FSB 1600 CPU Support ( Appears only if CPU supports FSB 1600)
This item will show and provide more options if your CPU is supporting FSB1600. If it is ena-
bled, then FSB is set to 1600MHz and you can not overclock further. If it is disabled, then you
can use other items in this menu to congure your system.
► CPU Clock
This option is used to set the CPU clock.
► PCI Express Clock
This option is used to set the speed of PCI Express slot. It may enhance the graphics card
speed.
► CPU Voltage Regulator
This option is used to regulate the CPU voltage.
► DRAM Voltage Regulator
This option is used to regulate the DRAM voltage.
► Spread Spectrum
If you enabled this function, it can signicantly reduce the EMI (Electromagnetic Interference)
generated by the system, so to comply with FCC regulation. But if overclocking is activated,
you had better disable it.
► DRAM Conguration
Press <Enter> to go to its submenu.
► DRAM Timing Selectable
This item is used to enable/disable provision of DRAM timing by SPD device. The Serial
Presence Detect (SPD) device is a small EEPROM chip, mounted on a DDR2 memory
module. It contains important information about the module's speed, size, addressing mode
and various other parameters, so that the motherboard memory controller (chipset) can
better access the memory device. Select [Manual], then you can congure DRAM timing by
yourselves.
