Frequency/Voltage Control - MSI K9NU Neo-V Handbuch

Frequency/Voltage Control

Current CPU Clock
It shows the current clock of CPU. Read-only.
Cool'n'Quiet
This item enables or disables the Cool'n'Quiet Function. Cool'n'Quiet is a special feature
designed only for AMD Athlon64 processor, and with Cool'n'Quiet, the system will be capable of
detecting the system working status. When the system is idle for a certain time, the CPU clock
will decrease automatically, and once the system is waken up, the CPU clock will return to its
previous status. Note that for the purpose of ensuring the stability of Cool'n'Quiet function, it is
always recommended to have the memories plugged in DIMM1.
Adjust CPU Ratio & Voltage/ Adjust DDR2 Memory Frequency
Adjust these items to be [Manual], you will be able to see and adjust more items for overclocking.
CPU Ratio/ Adjust CPU FSB Frequency/ DDR2 Memory Frequency/ Adjust PCI Express
Frequency
These items let you to adjust CPU ratio, CPU FSB frequency, memory frequency, or PCI Express
frequency. You can overclock the processor, memory, and PCI-E card by adjusting these items.
CPU Voltage/ DDR2 Memory Voltage/ Chipset Voltage
Adjusting the CPU/ DDR voltage can increase the CPU/ DDR speed. The chipset voltage can
also be adjusted for overclocking. Any changes made to these settings may cause a stability
issue, so changing the DDR and chipset voltage for long-term purpose is NOT recommended.
HT Link Speed
This setting specifies the maximum operating frequency of the link's transmitter clock.
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, select the desired range for EMI reduction.
Remember to disable Spread Spectrum function 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.
