CPU P State Control Menu
Note: This submenu is available when “Power Performance Tuning” is set to BIOS Controls EPB.
AVX P1 (Available when "SpeedStep (P-States)" is set to Enabled)
Use this feature to set the appropriate TDP level for the system. The Intel Advanced Vector 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-States)" is set to Enabled:
-
SST-PP Level
-
Capable
-
Core Count
-
P1 Ratio
-
Package TDP (W)
-
DTS_Max
SpeedStep (P-States)
Enhanced Intel SpeedStep Technology (EIST) allows the system to automatically adjust processor voltage and core frequency in an effort to reduce power consumption and heat dissipation. Refer to Intel’s website for detailed information. The options are Disabled and Enable.
EIST PSD Function (Available when "SpeedStep (P-States)" is set to Enabled)
This feature reduces the latency that occurs when one P-state changes to another, thus allowing the transitions to occur more frequently. This will allow for more demand-based P-state switching to occur based on the real-time energy needs of applications so that the power-to-performance balance can be optimized for energy efficiency. The options are HW_ALL and SW_ALL.
Turbo Mode (Available when "SpeedStep (P-States)" is set to Enabled)
Select Enable to allow the CPU to operate at the manufacturer-defined turbo speed by increasing CPU clock frequency. This feature is available when it is supported by the processors used in the system. The options are Disabled and Enabled.
