CPU Thermal Throttling
You may select [Enabled] to enable P4 CPU internal thermal control mecha-
nism to keep the CPU from overheated.
No-Excute Memory Protection
No-Execution (NX) Memory Protection Technology is an enhancement to the
IA-32 Intel Architecture. An IA-32 processor with "No Execute (NX) Memory
Protection" can prevent data pages from being used by malicious software to
execute code. This option will be hidden if the current CPU does not support
No-Excute Memory Protection.
Hyper Threading Technology
To enable this feature, it requires a computer system with an Intel Pentium
processor that supports Hyper-Threading technology and an operating system
that includes optimization for this technology, such as Microsoft
XP. Set to [Enabled] if using Microsoft
2.4.18 or higher. This option will be hidden if the installed CPU does not sup-
port Hyper-Threading technology.
Intel (R) SpeedStep(tm) tech.
Intel (R) SpeedStep(tm) tech. is Intel's new power saving technology. Proces-
sor can switch between multiple frequency and voltage points to enable power
savings. The default value is [Auto]. Configuration options: [Auto], [Enabled]
and [Disabled]. If you install Windows
the "Power Schemes" as "Portable/Laptop" to enable this function. If you
install Windows Vista

to [Enabled]. This item will be hidden if the current CPU does not support Intel
(R) SpeedStep(tm) tech..
Please note that enabling this function may reduce CPU voltage and lead to system
stability or compatibility issue with some power supplies. Please set this item to
[Disable] if above issue occurs.
Intel (R) C-STATE tech.
Intel (R) C-STATE tech. is achieved by making the power and thermal control
unit part of the core logic and not part of the chipset as before. Migration of the
power and thermal management flow into the processor allows us to use a
hardware coordination mechanism in which each core can request any C-state
it wishes, thus allowing for individual core savings to be maximized. The CPU
C-state is determined and entered based on the lowest common denominator
of both cores' requests, portraying a single CPU entity to the chipset power
management hardware and flows. Thus, software can manage each core
independently, while the actual power management adheres to the platform
and CPU shared resource restrictions. Configuration options are: [C2], [C3],
[C4] and [Disabled]. The default value is [Disabled].
