Intel

 Hyper-Threading Technology
The processor supports Intel
®
 Hyper-Threading Technology (Intel
®
 HT Technology) 
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:

 Turbo Boost Technology
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.
