will automatically change in ac cordance with the setting of Adjust DDR
M emory Frequency. Please note you must reboot the system to let the
change take effect. Setting options: [100 MHz], [133MHz], [166MHz], [200MHz].
Adjust CPU FSB Frequency
This item allows you to select the CPU Front Side Bus clock frequency (in MHz)
and overclock the processor by adjusting the FSB clock to a higher frequency.
Setting options: [200]~[320]
Adjust PCI Express Frequency
User can place an artificial PCI Express clock limit on the system. Setting
options: [100]~[200].
Ratio/Vcore Change
This field allows you to select the CPU Ratio. Setting to [Auto] enables CPU
Ratio automatically to be determined by SPD. Setting options: [Auto], [Manual].
Adjust CPU Ratio
This item allows you to adjust the CPU ratio. Setting to [Startup] enables the
CPU running at the fastest speed which is detected by system. Setting
options are: [Startup], [x4]~[x25].
CPU Voltage
The settings are used to adjust the CPU clock multiplier (ratio) and CPU
corevoltage (Vcore). These settings offer users a tool to overclock the
system.
M emory Voltage
Adjusting the DDR voltage can increase the DDR speed. Any changes made to
this setting may cause a stability issue, so changing the DDR voltage for
long-term purpose is NOT recommended.
LDT Bus Voltage
This item specifies the maximum operating frequency of the link's transmitter
clock. Setting options: [1.20], [1.25], [1.30], [1.35], [1.40], [1.45], [1.50].
Auto Disable PCI Clock
This item is used to auto detect the PCI slots. When set to [Enabled], the system
will remove (turn off) clocks from empty PCI slots to minimize the electromag-
netic interference (EMI). Settings: [Enabled], [Disabled].
Spread Spectrum
W hen the motherboard's clock generator pulses, the extreme values (spikes) of
the pulses creates EMI (Electromagnetic Interference). The Spread Spectrum
function reduces the EMI generated by modulating the pulses so that the spikes
of the pulses are reduced to flatter curves. If you do not have any EMI problem,
leave the setting at [Disabled] for optimal system stability and performance. But
if you are plagued by EMI, activate the Spread Spectrum for EMI reduction.
Remember to disable Spread Spectrum if you are overclocking because even a
