Spread Spectrum

This function reduces the EMI (Electromagnetic Interference) generated by modulating clock generator pulses.

Important

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 value of Spread Spectrum for EMI reduction.

The greater the Spread Spectrum value is, the greater the EMI is reduced, and the system will become less stable. For the most suitable Spread Spectrum value, please consult your local EMI regulation.

Remember to disable Spread Spectrum 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.

Vdroop Offset Control

This item is used to select the VDroop Offset control mode.

CPU Core OCP Expander

This item is used to expand the limitation of CPU Over Current Protection. The higher expanding value indicates less CPU protection. So please adjust the CPU voltage carefully if needed.

CPU Core Engine Speed

This item allows you to increase the PWM working speed to stabilize CPU Core voltage and minimize ripple range. Increasing the PWM working speed will cause higher temperture of MOSFET. So please make sure a cooling solution is well-prepared for MOSFET before you increase the value.

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 items are used to adjust the voltage of CPU, Memory, GPU and chipset.

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

These items show current CPU/ DRAM/ GPU voltage. Read-only.
