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.
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.
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 over
-
clocked processor to lock up.
VDroop Control
Ths 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 chpset.
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.
Overclockng Pro󰘰les
Press <Enter> to enter the sub-menu.
Overclockng Pro󰘰le 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 settngs, and you can to load the settngs from the stored pro󰘰le.
OC Retry Count
When overclockng has faled, settng ths tem as [1, 3] wll allow system to reboot
1/ 3 tmes wth the same overclocked con󰘰guraton. If overclockng has faled every
tme, the system wll restore the defaults.
