► 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 ena�le/disa�le the C1E support.
► Hyper-Threading
This item is used to ena�le/disa�le the Hyper-Threading Technology feature.
► Execute Disable Bit
This item is used to ena�le/disa�le the Execute Disa�le Bit feature.
Intel's Execute Disa�le Bit functionality can help prevent certain classes of malicious �uffer
overflow attacks when combined with a supporting operating system.
Execute Disa�le Bit allows the processor to classify areas in memory �y where application
code can execute and where it cannot. When a malicious worm attempts to insert code in the
�uffer, the processor disa�les code execution, preventing damage and worm propagation.
Replacing older computers with Execute Disa�le Bit-ena�led systems can halt worm attacks,
reducing the need for virus-related repairs. By com�ining Execute Disa�le 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 �e displayed only when the CPU is supporting this
feature and the setting is used to ena�le/disa�le it.
► CPU C6 Report
This item is used to ena�le or disa�le CPU C�(ACPI C3) report to OS.
► Package C State limit
It is used to select the C-State mode.
