Intel (R) TurboMode tech
Use this item to enable or disable Intel (R) Turbo Boost Technology. Turbo
mode allows processor cores to run faster than marked frequency in specific
condition. The default value is [Enabled].
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 low-
est common denominator of both cores’ requests, portraying a single CPU
entity to the chipset power management hardware and flows. Thus, soft-
ware can manage each core independently, while the actual power man-
agement adheres to the platform and CPU shared resource restrictions.
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.
Hyper Threading Technology
To enable this feature, it requires a computer system with an Intel Core
TM
i7
processor that supports Hyper-Threading technology and an operating system
that includes optimization for this technology, such as Microsoft
®
Windows
®
XP / Vista
TM
/ 7. Set to [Enabled] if using Microsoft
®
Windows
®
XP, Vista
TM
,
7 or Linux kernel version 2.4.18 or higher. This option will be hidden if the
installed CPU does not support Hyper-Threading technology.
Active Processor Cores
Use this item to select the number of cores to enable in each processor package.
Configuration options: [All], [1] and [2]. The default value is [All].
A20M
Use this item to enable or disable A20M. Legacy OS and AP may need A20M
enabled. The default value is [Disabled].
Intel (R) SpeedStep(tm) tech
Intel (R) SpeedStep(tm) tech is Intel’s new power saving technology. Pro-
cessor can switch between multiple frequency and voltage points to en-
able power savings. The default value is [Enabled]. Configuration options:
[Auto], [Enabled] and [Disabled]. If you install Windows
®
XP and select
[Auto], you need to set the “Power Schemes” as “Portable/Laptop” to en-
able this function. If you install Windows
®
Vista
TM
/ 7 and want to enable
this function, please set this item to [Enabled]. This item will be hidden if the
current CPU does not support Intel (R) SpeedStep(tm) tech.
