This option is set to Disabled by default.
Intel SST-CP Enables Intel SST-CP. This option is displayed and selectable for each
system profile mode. This option is set to Disabled by default.
Optimized Power Mode When set to Enabled, processor is turned for lower power
consumption. Also sets C1E to Enabled, sets CPU Power Management
to System DBPM mode, sets Energy Efficient Policy to Performance,
and sets Uncore Frequency to Dynamic.
x2APIC Mode Enables or disables x2APIC mode. This option is set to Enabled by
default.
NOTE: For two processors 64 cores configuration, x2APIC mode is
not switchable if 256 threads are enabled (BIOS settings: All CCD,
cores, and logical processors enabled).
AVX ICCP Pre-Grant License Enables or disables AVX ICCP Pre-Grant License. This option is set to
