*******Ratio and Clock Setting*******
► Target CPU Core Speed
This item shows target CPU core speed.
► CPU Clock
This item allows you to set CPU clock.
► CPU Clock vs Memory Speed
This item allows you to set the ratio between CPU Clock and Memory Speed. The normal
memory speed of DDR2 is equal to twice that of DRAM clock.
[Auto]:Set the CPU clock and memory speed automatically according to the range of CPU clock.
You also can select the ratio between CPU clock and memory speed through the
options:[1:2]; [1:2.4]; [1:2.665]; [1:3]; [1:3.2]; [1:3.3325]; [1: 4 CPU200]; [1:4 CPU266]; [1:4
CPU333]; [1:4 CPU400].
►System Memory Speed
This item shows the System Memory Speed.
► PCI Express Clock
This item allows you to adjust the PCI Express bus clock.
► PCI Clock
This item allows you to adjust the PCI bus clock. Configuration options:[Auto] ; [33.6 MHz];
[37.3 MHz]; [42.0 MHz].
************Miscellaneous************
► Auto Detect PCI Clock
This item is used to allow the system to supply the PCI slot bus clock if system detected a PCI
add-on card on the slot.
► Spread Spectrum
If you enabled this function, it can significantly reduce the EMI (Electro Magnetic Interference)
generated by the system, so to comply with FCC regulation. But if overclocking is activated,
you better disable it.
