No Execute Mode Memory Protection (*Available when supported by the
CPU and the OS.)
Set to Enabled to enable Execute Disable Bit and allow the processor to classify
areas in memory where an application code can execute and where it cannot, and
thus preventing a worm or a virus from inserting and creating a fl ood of codes to
overwhelm the processor or damage the system during an attack.
(*Note: this feature is available when your OS and your CPU support the function
of Execute Disable Bit.) The options are Disabled and Enabled. (Note: For more
information regarding hardware/software support for this function, please refer to
Intel's and Microsoft's web sites.)

Set to Enabled to use Thermal Management 2 (TM2) which will lower CPU voltage

regulated via CPU Internal Clock modulation when the CPU temperature reaches
the overheat threshold.
Adjacent Cache Line Prefetch (*Available when supported by the CPU.)
The CPU fetches the cache line for 64 bytes if this option is set to Disabled. The
CPU fetches both cache lines for 128 bytes as comprised if Enabled. The options
