► Server Class
This item is used to use the Intel recommended prefech settings. Default option is:[Custom].
► 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
automatically prefetch data and code for the processor.
When disabled, the processor’s hardware prefetcher will be disabled.
► Adjacent Cache Line Prefetch (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.
► Power Technology
This item is used to enable or disable the power management features. Default value
is:[Energy Efficient].
