Cell Menu

Current CPU Clock
It shows the current CPU clock. Read-only.
Adjust CPU Ratio
This item allows you to adjust the CPU ratio. Setting range is from [8] to [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 electromagnetic interference (EMI).

Spread Spectrum

When 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, set to Enabled for EMI reduction. Remember to
disable Spread Spectrum if you are overclocking because even a slight jitter can introduce a
temporary boost in clock speed which may just cause your overclocked processor to lock up.

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.
Memory 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.
