► C1E Support(Appears only when CPU supports)
C1E represents Enhanced HALT State. It is a feature which 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.
► Hyper-Threading
This item is used to enable/disable the Hyper-Threading Technology feature.
► 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.
► Intel 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.
► CPU C6 Report
This item is used to enable or disable CPU C6(ACPI C3) report to OS.
► Package C State limit
It is used to select the C-State mode.
► CPU Internal PLL Overvoltage
This item is used to enable or disable the CPU Internal PLL Overvoltage.
