Spread Spectrum
When the manboard’s clock generator pulses, the extreme values (spkes) of the pulses
create EMI (Electromagnetc Interference). The Spread Spectrum functon reduces the
EMI generated by modulatng the pulses so that the spkes of the pulses are reduced
to flatter curves.
Important
If you do not have any EMI problem, leave the settng at [Dsabled] for optmal system
stablty and performance. But f you are plagued by EMI, select the value of Spread
Spectrum for EMI reducton.
The greater the Spread Spectrum value s, the greater the EMI s reduced, and the
system wll become less stable. For the most sutable Spread Spectrum value, please
consult your local EMI regulaton.
Remember to dsable Spread Spectrum f you are overclockng because even a slght
jtter can ntroduce a temporary boost n clock speed whch may just cause your over-
clocked processor to lock up.
VDroop Control
Ths tem s used to select the VDroop control mode.
CPU Core Voltage/ CPU I/O Voltage/ DRAM Voltage/ GPU Voltage/ System Agent
Voltage(SA)/ CPU PLL Voltage/ DDR_VREF_CA_A/ DDR_VREF_CA_B/ DDR_VREF_
DA_A/ DDR_VREF_DA_B/ PCH 1.05
These tems are used to adjust the voltage of CPU, Memory and chpset.
Current CPU Core Voltage/ Current CPU I/O Voltage/ Current DRAM Voltage/ Current
GPU Voltage
These tems show current CPU Core/ CPU I/O/ DRAM/ GPU voltage. Read-only.
Overclockng Profiles
Press <Enter> to enter the sub-menu.
Overclockng Profile 1/ 2/ 3/ 4/ 5/ 6
Press <Enter> to enter the sub-menu. In the sub-menu, these tems are used to save
the current settngs, and you can to load the settngs from the stored profile.
OC Retry Count
When overclockng has faled, settng ths tem as [1, 3] wll allow system to reboot
1/ 3 tmes wth the same overclocked configuraton. If overclockng has faled every
tme, the system wll restore the defaults.
