Intel Virtualization Technology: Select Enabled to use Virtualization Technology to allow one platform to run
multiple operating systems and applications in independent partitions, creating multiple virtual systems in one
physical computer.
IMPORTANT:The following feature is only available if supported by the processor and/or operating system.
Execute-Disable Bit Capability: Set to Enabled to enable the Execute Disable Bit which will allow the
processor to designate areas in the system memory where an application code can execute and where it
cannot, thus preventing a worm or a virus from flooding illegal codes to overwhelm the processor or damage
the system during an attack.
IMPORTANT:The following feature is only available if supported by the processor and/or operating system.
Simultaneous Multi-Threading: Set to Enabled to use simultaneous multi-threading technology, which will
result in increased CPU performance.
Active Processor Cores: Set to Enabled to use a processor's second core and beyond. The options are All, 1
and 2.
Intel EIST Technology: EIST (Enhanced Intel SpeedStep Technology) allows the system to automatically
adjust processor voltage and core frequency in an effort to reduce power consumption and heat dissipation.
Please refer to Intel's web site for detailed information. The options are Disabled (Disable GV3) and Enabled
(Enable GV3).
Intel® Turbo Boost (Available when Intel® EIST Technology is enabled): Select Enabled to use the Turbo
Mode to boost system performance.
Performance/Watt Select: When selected the "Power Optimized" (Turbo Boost engages after p) state is
sustained for more than 2 seconds. In the default setting "Traditional", Turbo Boost engages even for a P0
state of less than 2 seconds.
Intel C-STATE Tech: If Enabled, C-State is set by the system automatically to either C2, C3 or C4.
C3 State: This feature allows the user to decide how the onboard 5500 Series processor will act at C3 State.
C6 State: This feature allows the user to decide how the onboard 5500 Series processor will act at C6 State.
C-State package limit setting: If set to Auto, the BIOS will automatically set the limit on the C-State package
register.
C1 Auto Demotion: When Enabled, the CPU will conditionally demote C3, C6 or C7 requests to C1 based on
un-core auto-demote information.
C3 Auto Demotion: When Enabled, the CPU will conditionally demote C6 or C7 requests to C3 based on un-
core auto-demote information.
Clock Spread Spectrum: Select Enabled to use the feature of Clock Spectrum, which will allow the BIOS to
monitor and attempt to reduce the level of Electromagnetic Interference caused by the components whenever
needed.
