CPU Configuration
► C1E Support
C1E represents Enhanced HALT State. It is a feature which Intel CPU uses to reduce power
consumption when in halt state. C1E drops the CPU's multiplier and voltage to lower levels
when a HLT (halt) command is issued. This item is used to enable/disable the C1E support.
consumption when in halt state. C1E drops the CPU's multiplier and voltage to lower levels
when a HLT (halt) command is issued. This item is used to enable/disable the C1E support.
► 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.

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 proces-
sor 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.

► Limit CPUID MaxVal
This item is used to enable or disable CPUID maximum value limit configuration. Set Limit
CPUID MaxVal to 3, it should be [Disabled] for WinXP.
CPUID MaxVal to 3, it should be [Disabled] for WinXP.
► Virtualization Technology
(Appears only when CPU supports)
Virtualization (i.e. Intel® Vanderpool Technology) allows a platform to run multiple operating
systems and applications in independent partitions or “containers.” One physical compute
system can function as multiple “virtual” systems. Vanderpool Technology can help improve
future virtualization solutions. This item will be displayed only when the CPU is supporting this
feature and the setting is used to enable/disable it.
