instructions into L2 cache from memory for tuning the CPU perfor-
mance.
[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 la-
tency 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.

[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-Statel" 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.
