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.

Extensions (Intel AVX) P1 feature allows you to set the base P1 ratio for Streaming SIMD
Extensions (SSE) and AVX workloads. Each P1 ratio has the corresponding AVX Impressed
Current Cathodic Protection (ICCP) pre- grant license level, which refers to the selection
between different AVX ICCP transition levels. The options are Nominal, Level 1, and Level 2.
This feature is CPU-dependent.
The following information is CPU- dependent and will be displayed when "SpeedStep (P-
