Race To Halt (RTH)
This item enables or disables Race To Halt feature. RTH will dynamically increase CPU frequency in
order to enter pkg C-State faster to reduce overall power. (RTH is controlled through MSR 1FC bit
20)
Options: Enabled (Default) / Disabled
Intel(R) Speed Shift Technology
This item enables or disables Intel(R) Speed Shift Technology support. Enabling will expose the
CPPC v2 interface to allow for hardware controlled P-states.
Options: Enabled (Default) / Disabled

the default values for Power Limit 1 and Power Limit 1 Time Window.
Options: Enabled (Default) / Disabled
Power Limit 1
This item Power Limit 1 value in Milli Watts. BIOS will round to the nearest 1/8W when
programming. 0 = no custom override. For 12.50W, enter 12500.
Options: 95000 (Default)
Power Limit 2 Override
This item enables or disables Power Limit 2 Override. If this option is disabled, BIOS will program
the default values for Power Limit 2.
Options: Enabled (Default) / Disabled
Power Limit 2
This item Power Limit 2 value in Milli Watts. BIOS will round to the nearest 1/8W when
programming. If the value is 0, BIOS will program this value as 1.25*TDP. For 12.50W, enter 12500.
Processor applies control policies such that the package power does not exceed this limit.
Options: 122000 (Default)
Energy Efficient P-state
This item enables or disables Energy Efficient P-state feature. When set to 0, will disable access
to ENERGY_PERFORMANCE_BIAS MSR and CPUID Function 6 ECX [3] will read 0 indicating no
support for Energy Efficient policy setting.
Options: Enabled (Default) / Disabled
Energy Efficient Turbo
This item enables or disables Energy Efficient Turbo feature. This feature will opportunistically
lower the turbo frequency to increase efficiency.
Options: Enabled (Default) / Disabled
C states
This item enables or disables CPU Power Management. Allows CPU to go to C states when it's not
100% utilized.
Options: Auto (Default) / Enabled / Disabled
Enhanced C-states
This item enables or disables C1E. When enabled, CPU will switch to minimum speed when all
cores enter C-State.
Options: Enabled (Default) / Disabled
