The following items appear only when you set the CPU Voltage Frequency to [Auto]. VRM Spread Spectrum [Disabled] Enable the VRM Spread Spectrum to enhance system stability. Configuration options: [Disabled] [Enabled] Active Frequency Mode [Disabled] Set this item to [Enabled] to help enhance the power saving condition while switching frequencies. While a higher frequency makes the VRM transient response much faster, switching frequencies affect the VRM thermal components. Configuration options: [Disabled] [Enabled] CPU Power Phase Control [Auto] Allows you to set the power phase control of the CPU. Configuration options: [Auto] [Standard] [Optimized] [Extreme] [Manual Adjustment] DO NOT remove the thermal module when setting this item to [Extreme] and [Manual Adjustment]. The thermal conditions should be monitored. The following item appears only when you set the CPU Power Phase Control to [Manual Adjustment]. Manual Adjustment [Fast] Allows you to set a faster phase response for the CPU to increase system performance or to slower phase response to decrease DRAM power efficiency. Configuration options: [Ultra Fast] [Fast] [Medium] [Regular] CPU Power Duty Control [T.Probe] DIGI + VRM Duty Control adjusts the current of every VRM phase and the thermal conditions of every phase component. [T. Probe] Select to maintain the VRM thermal balance. [Extreme] Select to maintain the current VRM balance. DO NOT remove the thermal module. The thermal conditions should be monitored. CPU Current Capability [Auto] DIGI+ VRM CPU Current Capability provides wider total power range for overclocking. A higher value setting gets higher VRM power consumption delivery and extends the overclocking frequency range simultaneously. Configuration options: [Auto] [100%] [110%] [120%] [130%] [140%] Choose a higher value when overclocking, or under a high CPU loading for extra power support. CPU Power Thermal Control [130] A higher temperature brings a wider CPU power thermal range and extends the overclocking tolerance to enlarge the O.C. potential. Use the or keys to adjust the value. The values depend on the CPU installed. 3-16 Chapter 3: BIOS setup Chapter 3
