Intel

The processor supports Intel

that allows an execution core to function as two logical processors. While some

execution resources such as caches, execution units, and buses are shared, each

logical processor has its own architectural state with its own set of general-purpose

registers and control registers. This feature must be enabled using the BIOS and

requires operating system support.

Intel recommends enabling Hyper-Threading Technology with Microsoft Windows

Vista*, Microsoft Windows* XP Professional/Windows* XP Home, and disabling Hyper-

Threading Technology using the BIOS for all previous versions of Windows operating

systems. For more information on Hyper-Threading Technology, see:

Intel

Turbo Boost Technology is a feature that allows the processor core to

opportunistically and automatically run faster than its rated operating frequency if it is

operating below power, temperature, and current limits. Maximum frequency is

dependent on the SKU and number of active cores. No special hardware support is

necessary for Intel Turbo Boost Technology. BIOS and the operating system can enable

or disable Intel Turbo Boost Technology.

Note:

Intel Turbo Boost Technology may not be available on all SKUs. Refer to the processor

specification update for details.
