CPU Ampltude Control/ PCI Express Ampltude Control
These tems are used to select the CPU/ PCI Express clock ampltude.
CPU CLK Skew/ IOH CLK Skew
These tems are used to select the CPU/ IOH chpset clock skew. They can help
CPU to reach the hgher overclockng performace.
Adjust PCI Frequency (MHz)
Ths 󰘰eld allows you to select the PCI frequency (n MHz).
Adjust PCI-E Frequency (MHz)
Ths 󰘰eld allows you to select the PCIE frequency (n MHz).
Auto Dsable DRAM/PCI Frequency
When set to [Enabled], the system wll remove (turn o󰘯) clocks from empty DIMM and
PCI slots to mnmze the electromagnetc nterference (EMI).
CPU Load Lne Calbraton
When set to [Enabled], system wll automatcally 󰘰x the vcore droop ssue of CPU, and
the CPU can receve stable voltage n overclockng.
CPU Voltage (V)/ CPU Vcore/ CPU PLL Voltage (V)/ QPI Voltage (V)/ DRAM Voltage
(V)/ DDR_VREF_CA_A Voltage (V)/ DDR_VREF_CA_B Voltage (V)/ DDR_VREF_CA_
C Voltage (V)/ DDR_VREF_DQ_A Voltage (V)/ DDR_VREF_DQ_B Voltage (V)/ DDR_
VREF_DQ_C Voltage (V)/ NB Voltage (V)/ ICH Voltage (V)
These tems are used to adjust the voltage of CPU, Memory and chpset.
Spread Spectrum
When the manboard’s clock generator pulses, the extreme values (spkes) of the pulses
create EMI (Electromagnetc Interference). The Spread Spectrum functon reduces the
EMI generated by modulatng the pulses so that the spkes of the pulses are reduced to
󰘱atter curves. If you do not have any EMI problem, leave the settng at Dsabled for opt

mal system stablty and performance. But f you are plagued by EMI, set to Enabled for
EMI reducton. Remember to dsable Spread Spectrum f you are overclockng because
even a slght jtter can ntroduce a temporary boost n clock speed whch may just cause
your overclocked processor to lock up.
Important
If you do not have any EMI problem, leave the settng at [Dsabled] for optmal system
stablty and performance. But f you are plagued by EMI, select the value of Spread
Spectrum for EMI reducton.
The greater the Spread Spectrum value s, the greater the EMI s reduced, and the
system wll become less stable. For the most sutable Spread Spectrum value, please
consult your local EMI regulaton.
