Datasheet, Volume 1

These extensions enhance two areas:

• The launching of the Measured Launched Environment (MLE)
• The protection of the MLE from potential corruption

The enhanced platform provides these launch and control interfaces using Safer Mode 
Extensions (SMX).

The SMX interface includes the following functions:

• Measured/Verified launch of the MLE
• Mechanisms to ensure the above measurement is protected and stored in a secure 

location

• Protection mechanisms that allow the MLE to control attempts to modify itself

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 7*, 
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 is a feature that allows the processor core to 

opportunistically and automatically run faster than its rated operating frequency/render 
clock if it is operating below power, temperature, and current limits. The Intel Turbo 
Boost Technology feature is designed to increase performance of both multi-threaded 
and single-threaded workloads. Maximum frequency is dependant on the SKU and 
number of active cores. No special hardware support is necessary for Intel Turbo Boost 
Technology. BIOS and the OS can enable or disable Intel Turbo Boost Technology. 
Compared with previous generation products, Intel Turbo Boost Technology will 
increase the ratio of application power to TDP. Thus, thermal solutions and platform 
cooling that are designed to less than thermal design guidance might experience 
thermal and performance issues since more applications will tend to run at the 
maximum power limit for significant periods of time.  

Intel Turbo Boost Technology may not be available on all SKUs.
