CPUID MaxVal to 3. Should be �Disabled�� for WinXP.
► C1E Function
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.
► Execute Disable 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.
► Virtualization Technology
Virtuali�ation (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 virtuali�ation solutions. This item will be displayed only when the CPU is supporting this
feature and the setting is used to enable/disable it.
► Frequency Unlimit
It means the processor is not ratio locked and has no factory configured maximum ratio limit
on the Smithfield XE multi-processing CPU core.
► Core Multi-Processing
When disabled, it will disable one execution core of each CPU die. It is going to provide
backward compatibility, any way, keep it enabled.
