CPU Configuration
► EIST Function
You can select the EIST (Processor Power Management, PPM) through this item.
► 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.
► Limit CPUID MaxVal
This item is used to enable or disable CPUID maximum value limit configuration. Set Limit
CPUID Maximum to 3. 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
Enhanced Intel SpeedStep® technology (EIST) allows the system to dynamically
adjust processor voltage and core frequency, which can result in decreased average
power consumption and decreased average heat production. There are some system
requirements must be met, including CPU, chipset, motherboard, BIOS and operation
system. Please refer to Intel website for more information.
