CPU C3/C6 Report (Note) Allows you to determine whether to let the CPU enter C3/C6 mode in system halt state. When enabled, the CPU core frequency and voltage will be reduced during system halt state to decrease power consumption. The C3/C6 state is a more enhanced power-saving state than C1. Options available: Enabled/Disabled. Default setting is Enabled. Package C State Limit Configure state for the C-State package limit. Options available: C0/C1/C6/C7/No Limit. Default setting is No Limit. Energy Performance Energy Performance Bias is Intel CPU function. The larger value in MSR_ENERGY_PERFORMANCE_BIAS register, CPU will save more power but lose more performance. Note: This register will be changed by OS too if OS support it like Windows 2008 or newer Linux. Options available: Performance : Write value 0 into MSR_ENERGY_PERFORMANCE_BIAS Balanced Performance: Write value 7 into MSR_ENERGY_PERFORMANCE_BIAS Balanced Energy: Write value 11 into MSR_ENERGY_PERFORMANCE_BIAS Energy Efficient: Write value 15 into MSR_ENERGY_PERFORMANCE_BIAS Default setting is Performance.

CPU C3/C6 Report
(Note)
Allows you to determine whether to let the CPU enter C3/C6 mode in system halt state. When enabled,
the CPU core frequency and voltage will be reduced during system halt state to decrease power
consumption. The C3/C6 state is a more enhanced power-saving state than C1.
Options available: Enabled/Disabled. Default setting is
Enabled
.
Package C State Limit
Configure state for the C-State package limit.
Options available: C0/C1/C6/C7/No Limit. Default setting is
No Limit
.
Energy Performance
Energy Performance Bias is Intel CPU function.
The larger value in MSR_ENERGY_PERFORMANCE_BIAS register,
CPU will save more power but lose more performance.
Note:
This register will be changed by OS too if OS support it like Windows 2008 or newer Linux.
Options available:
Performance : Write value 0 into MSR_ENERGY_PERFORMANCE_BIAS
Balanced Performance: Write value 7 into MSR_ENERGY_PERFORMANCE_BIAS
Balanced Energy: Write value 11 into MSR_ENERGY_PERFORMANCE_BIAS
Energy Efficient: Write value 15 into MSR_ENERGY_PERFORMANCE_BIAS
Default setting is
Performance
