Intel (R) Virtualization tech.
When this option is set to [Enabled], a VMM (Virtual Machine Architecture)
can utilize the additional hardware capabilities provided by Vanderpool
Technology. This option will be hidden if the installed CPU does not support
Intel (R) Virtualization Technology.
CPU Thermal Throttling
You may select [Enabled] to enable P4 CPU internal thermal control mecha-
nism to keep the CPU from overheated. This option will be hidden if the
current CPU does not support CPU Thermal Throttling.
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
4 processor that supports Hyper-Threading technology and an operating
system that includes optimization for this technology, such as Microsoft
Windows XP. Set to [Enabled] if using Microsoft
®
kernel version 2.4.18 or higher. This option will be hidden if the installed
CPU does not support Hyper-Threading technology.
On-Demand Clock Modulation
This provides the On-Demand Clock Modulation duty cycle. It indicates the
clock on to clock off interval ratio. For example, if you set this option to
[75.0% On], your processor will work normally 75% of the time, and spend
the other 25% slacking off. Configuration options: [Auto], [Disabled],
[12.5% On], [25.0% On], [37.5% On], [50.0% On], [62.5% On], [75.0% On]
and [87.5% On]. The default value is [Auto].
Intel (R) SpeedStep(tm) tech.
Intel (R) SpeedStep(tm) tech. is Intel's new power saving technology.
Processor 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
[Auto], you need to set the "Power Schemes" as "Portable/Laptop" to en-
able this function. If you install Windows
function, please set this item 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.
