Advanced Power Management Configuration Menu
Power Performance Tuning
This feature allows either operating system (OS) or BIOS to control the EPB. The options are OS Controls EPB, BIOS Controls EPB, and PCEI Controls EPB. (PECI is the abbreviation for Platform Environment Control Interface. EPB is the abbreviation for Intel Performance and Energy Bias Hint.)
ENERGY_PERF_BIAS_CFG Mode (ENERGY PERFORMANCE BIAS CONFIGURATION Mode) (Available when "Power Performance Tuning" is set to BIOS Controls EPB)
Use this feature to configure the proper operation setting for your machine by achieving the desired system performance level and energy saving (efficiency) level at the same time. Select Performance to enhance system performance; however, this may consume more power as energy is needed to fuel the processors for operation. The options are Performance, Balanced Performance, Balanced Power, and Power.
