Energy performance
Optimize between performance and power savings.
Package power limit lock: When enabled PACKAGE_POWER_LIMIT MSR will be locked and a reset
will be required to unlock the register.
CPU Power limit1: CPU power limit1 value
CPU Power limit1 time: Time window which the power limit1 is maintained
CPU Power limit2: CPU power limit2 value
Platform power limit lock: When enable, PLATFORM_POWER_LIMIT MSD will be locked and a reset
will be required to unlock the register.
CPU Power Limit3: CPU Power Limit3 value
CPU Power Limit3 Time: Time window which the power limit3 is maintained
CPU Power Limit3 Duty Cycle: Specify the duty cycle in percentage that the CPU is required to
maintain over the configured Power Limit3 time windows.
DDR Power Limit1: DDR Power limit1 value
DDR Power Limit1 Time: Time window which the DDR Power Limit1 is maintained.
DDR Power Limit2: DDR Power limit2 value
1-Core Ratio Limit: This limit is for 1 core active. 0 means using the factory-configured value.
2-Core Ratio Limit: This limit is for 2 cores active. 0 means using the factory-configured value.
3-Core Ratio Limit: This limit is for 3 cores active. 0 means using the factory-configured value.
4-Core Ratio Limit: This limit is for 4 cores active. 0 means using the factory-configured value.
VR Current value lock
Locks VR Current value from further writes until a reset.
VR Current value
Voltage regulator current limit. 0 means AUTO.
CPU C States
Enable or disable CPU C states.
Enhanced C1 State: Enhanced C1 State
CPU C3 Report: Enable /disable CPU C3 report to OS
CPU C6 Report: Enable /disable CPU C6 report to OS
C6 Latency: Configure short/long latency for C6
CPU C7 Report: Enable /disable CPU C7 report to OS
C7 Latency: Configure short/long latency for C7
C1 state auto demotion: processor will conditionally demote C3/C6/C7 requests to C1 based on
uncore auto-demote information.
C3 state auto demotion: processor will conditionally demote C6/C7 requests to C3 based on uncore
