Execute Disable
Bit
The Execute Disable bit allows memory to be marked as executable or non-
executable, when combined with a supporting operating system. If code
attempts to run in non-executable memory the processor raises an error to
the operating system. This feature can prevent some classes of viruses or
worms that exploit buffer overrun vulnerabilities and can thus help improve
the overall security of the system. See the Intel® 64 and IA-32
Architectures Software Developer's Manuals for more detailed information.

Intel®
Virtualization
Tec hno log y
Processor virtualization that, when used in conjunction with Virtual Machine
Monitor software, enables multiple, robust independent software
environments inside a single platform.
Half ratio support
(N/2) for Core to
Bus ratio
Intel Core 2 Duo processors and Intel Core 2 Extreme processors support
the N/2 feature that allows having fractional core-to-bus ratios. This feature
provides the flexibility of having more frequency options and being able to
have products with smaller frequency steps.
