CPU Configuration
► Hyper-threading
Hyper-Threading Technology allows one physical processor package to be perceived as two
separate logical processors within the operating system. This option is used to enable or
disable the feature. It will be displayed only if your CPU is supporting this feature.
► Limit CPUID Maximum
This item is used to enable or disable CPUID maximum value limit configuration. It should be
[Disabled] for WinXP.
► Execute Disabled Bit
This item is used to enable/disable the Execute Disable Bit feature.
Intel’s Execute Disable Bit functionality can help prevent certain classes of malicious buffer
overflow attacks when combined with a supporting operating system.
Execute Disable Bit allows the processor to classify areas in memory by where application
code can execute and where it cannot. When a malicious worm attempts to insert code in the
buffer, the processor disables code execution, preventing damage and worm propagation.
Replacing older computers with Execute Disable Bit-enabled systems can halt worm attacks,
reducing the need for virus-related repairs. By combining Execute Disable Bit with anti-virus,
firewall, spyware removal, e-mail filtering software, and other network security measures, IT
managers can free IT resources for other initiatives.
► 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.
