Auto Detect DIMM/PCI CLK
This item allows you to enable/disable auto detect DIMM/PCI Clock. Turning off
the un-used PCI and DRAM clock may help to EMI issue. Since there is no PCI
clock routing specification for PICMG backplane, some system may have PCI
card detect issue. In that case, please disable this item.
The choice: Enabled, Disabled.
Spread Spectrum Modulated
This item allows you to enable/disable the spread spectrum modulate. The spread
spectrum technology also helps to alleviate the EMI.
The choice: Enabled, Disabled.
CPU Host Clock (CPU/PCI)
This item allows you to select the CPU speed. Over-clocking may cause system
hang or unstable.
There is no guarantee for any over-speed operation.
