The following table will explain the items in more detail:
Values
Meaning
Enabled If set to enabled the BIOS will detect the values for the PCI and
DIMM clocks
Auto Detect
DIMM /
PCI Clock
Disabled If disabled, the BIOS will use the values set on this page and on
the Advanced Chipset Features page.
Enabled
If set to enabled, the clock generator will modulate each clock
signal with a low frequency signal. This will improve EM
(Electro-Magnetic) Interference.
Spread
Spectrum
Modulated
Disabled The clock generator will not modulate the clock signals
This item allows setting of the CPU and PCI bus frequencies. If set
to default, the BIOS will select the values automatically.
Otherwise, if you have a 100MHz FSB CPU we recommend you
use the 100 / 33 Setting. If you have a 133Mhz FSB CPU we
recommend you use the 133 / 33 setting. Any other setting will
make the system operate without it specifications and we can not
guarantee proper functioning in that case. The other settings are:
90 / 30
95 / 31
100 / 33
101 / 33
102 / 34
