Logical Processor 
Idling
Enables you to improve the energy eciency of a system. It uses the operating system core parking algorithm and 
parks some of the logical processors in the system which in turn allows the corresponding processor cores to 
transition into a lower power idle state. This option can only be enabled if the operating system supports it. It is set 
to Disabled by default.
Congurable TDP Enables you to recongure the processor Thermal Design Power (TDP) levels during POST based on the power 
and thermal delivery capabilities of the system. TDP veries the maximum heat the cooling system is needed to 
dissipate. This option is set to Nominal by default.
NOTE: This option is only available on certain stock keeping units (SKUs) of the processors.
