(Note) This item is present only if you install a CPU that supports this feature. For more information
about Intel CPUs' unique features, please visit Intel's website.
CPU Multi-Threading
(Note)
Allows you to determine whether to enable all CPU cores and multi-threading function when using
an Intel
®
CPU that supports multi-core technology. This feature only works for operating systems
that support multi-processor mode.
Enabled Enables all CPU cores and multi-threading capability. (Default)
Disabled Enables only one CPU core.
Limit CPUID Max. to 3
(Note)
Allows you to determine whether to limit CPUID maximum value. Set this item to Disabled for
Windows XP operating system; set this item to Enabled for legacy operating system such as
Windows NT4.0. (Default: Disabled)
No-Execute Memory Protect
(Note)
Enables or disables Intel
®
Execute Disable Bit function. This function may enhance protection for
the computer, reducing exposure to viruses and malicious buffer overflow attacks when working
with its supporting software and system. (Default: Enabled)
CPU Enhanced Halt (C1E)
(Note)
Enables or disables Intel
®
CPU Enhanced Halt (C1E) function, a CPU power-saving function in
system halt state. When enabled, the CPU core frequency and voltage will be reduced during
system halt state to decrease power consumption. (Default: Enabled)
C2/C2E State Support
(Note)
Allows you to determine whether to let the CPU enter C2/C2E mode in system halt state. When
enabled, the CPU core frequency and voltage will be reduced during system halt state to descrease
power consumption. (Default: Disabled)
C4/C4E State Support
(Note)
Allows you to determine whether to let the CPU enter C4/C4E mode in system halt state. When
enabled, the CPU core frequency and voltage will be reduced during system halt state to descrease
power consumption. C4/C4E state is a more enhanced power-saving state than C2/C2E. This
item is configurable only if the C2/C2E State Support option is enabled. (Default: Disabled)
CPU Thermal Monitor 2 (TM2)
(Note)
Enables or disables Intel
®
CPU Thermal Monitor (TM2) function, a CPU overheating protection
function. When enabled, the CPU core frequency and voltage will be reduced when the CPU is
overheated. (Default: Enabled)
CPU EIST Function
(Note)
Enables or disables Enhanced Intel SpeedStep Technology (EIST). Depending on CPU loading,
Intel
®
EIST technology can dynamically and effectively lower the CPU voltage and core frequency
to decrease average power consumption and heat production. (Default: Enabled)
Virtualization Technology
(Note)
Enables or disables Intel
®
Virtualization Technology. Virtualization enhanced by Intel
®
Virtualization
Technology will allow a platform to run multiple operating systems and applications in independent
partitions. With virtualization, one computer system can function as multiple virtual systems.
(Default: Enabled)
