▶ Hardware Prefetcher [Enabled] Enables or disables the hardware prefetcher (MLC Streamer prefetcher). [Enabled] Allows the hardware prefetcher to automatically pre-fetch data and instructions into L2 cache from memory for tuning the CPU performance. [Disabled] Disables the hardware prefetcher. ▶ 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 [Auto] 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~C7s] The power-saving level from high to low is C7s, C7, C6, C3, C2, then C0. [No limit] No C-state limit for CPU. Chapter 3 3-23 BIOS Setup
