CPU Configuration
► Hardware Prefetcher
The processor has a hardware prefetcher that automatically analyzes its requirements and
prefetches data and instructions from the memory into the Level 2 cache that are likely to be
required in the near future. This reduces the latency associated with memory reads.
When enabled, the processor’s hardware prefetcher will be enabled and allowed to automati-
cally prefetch data and code for the processor.
When disabled, the processor’s hardware prefetcher will be disabled.
► Adjacent Cache Line Prefetcher
(Appears only when CPU supports)
The processor has a hardware adjacent cache line prefetch mechanism that automatically
fetches an extra 64-byte cache line whenever the processor requests for a 64-byte cache line.
This reduces cache latency by making the next cache line immediately available if the processor
requires it as well.
When enabled, the processor will retrieve the currently requested cache line, as well as the
subsequent cache line.
When disabled, the processor will only retrieve the currently requested cache line.
► EIST Function(Appear only when CPU supports)
You can select the EIST (Processor Power Management, PPM) through this item.
► Intel(R) Turbo Mode Tech
(Appears only when CPU supports)
Intel Turbo mode support, this item will take active after PPM item is enabled.
► Intel(R) C-STATE Tech
(Appears only when CPU supports)
C-states are states in which the CPU is idle. Usually, CPU idle is set to C2/C3/C4.

Enhanced Intel SpeedStep® technology (EIST) allows the system to dynamically adjust
processor voltage and core frequency, which can result in decreased average power
consumption and decreased average heat production. There are some system require-
ments must be met, including CPU, chipset, motherboard, BIOS and operation system.
Please refer to Intel Website for more information.
