Spread Spectrum

Ths functon reduces the EMI (Electromagnetc Interference) generated by modulatng

clock generator pulses.

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 Offset Control

Ths tem s used to select the CPU core Vdroop offset control mode.

Dgtal Compensaton Level

Ths tem s used to select the current compensaton speed when the MOS phases be

changed. For overclockng or full-loadng of system, t s recommended ths field set to

[hgh]. Please note that overclockng behavor and stablty s not guaranteed.

CPU Core OCP Expander

Ths tem s used to expand the lmtaton of CPU Over Current Protecton. The hgher

expandng value ndcates less CPU protecton. So please adjust the CPU voltage

carefully f needed.

CPU Core Swtchng Frequency

Ths tem allows you to specfic the CPU core swtchng frequency.

CPU Core 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, GPU and chpset.

Current CPU Core Voltage/ Current CPU I/O Core Voltage/ Current DRAM Voltage/

Current GPU Voltage

These tems show current CPU/ CPU I/O/ DRAM/ GPU voltage. Read-only.

Overclockng Profiles
