▶Adjacent Cache Line Prefetch [Enabled]
Enables or disables the CPU hardware prefetcher (MLC Spatial prefetcher).
[Enabled] Enables adjacent cache line prefetching for reducing the cache
latency time and tuning the performance to the specific application.
[Disabled] Enables the requested cache line only.
▶CPU AES Instructions [Enabled]
Enables or disables the CPU AES (Advanced Encryption Standard-New
Instructions) support. This item appears when a CPU supports this function.
[Enabled] Enables Intel AES support.
[Disabled] Disables Intel AES support.
▶Intel Adaptive Thermal Monitor [Enabled]
Enables or disables the Intel adaptive thermal monitor function to protect the CPU
from overheating.
[Enabled] Throttles down the CPU core clock speed when the CPU is over the
adaptive temperature.
[Disabled] Disables this function.
▶Intel C-State [Enabled]
C-state is a processor power management technology defined by ACPI.
[Auto] This setting will be configured automatically by BIOS.
[Enabled] Detects the idle state of system and reduce CPU power consumption
accordingly.
[Disabled] Disable this function.
▶C1E Support [Disabled]
Enables or disables the C1E function for power-saving in halt state. This item
appears when “Intel C-State” is enabled.
[Enabled] Enables C1E function to reduce the CPU frequency and voltage for
power-saving in halt state.
[Disabled] Disables this function.
▶Package C State limit [Auto]
This item allows you to select a CPU C-state mode for power-saving when system
is idle. This item appears when "Intel C-State" is enabled.
[Auto] This setting will be configured automatically by BIOS.
[C0~C6] The power-saving level from high to low is C6, C2, then C0.
▶Long Duration Power Limit (W) [Auto]
Sets the long duration TDP power limit for CPU in Turbo Boost mode.
▶Long Duration Maintained (s) [Auto]
Sets the maintaining time for "Long duration power Limit(W)".
▶Short Duration Power Limit (W) [Auto]
Sets the short duration TDP power limit for CPU in Turbo Boost mode.
▶CPU Current Limit (A) [Auto]
Sets maximum current limit of CPU package in Turbo Boost mode. When the
current is over the specified limit value, the CPU will automatically reduce the core
frequency for reducing the current.
