Terminology
A ‘#’ symbol after a signal name refers to an active low signal, indicating a signal is in
the active state when driven to a low level. For example, when RESET# is low, a reset
has been requested.
the active state when driven to a low level. For example, when RESET# is low, a reset
has been requested.
A ‘_N’ and ‘_P’ after a signal name refers to a differential pair.
Commonly used terms are explained here for clarification:
• 1366-land FC-LGA package — The Intel Xeon Processor 5500 Series is available
in a Flip-Chip Land Grid Array (FC-LGA) package, consisting of processor mounted
on a land grid array substrate with an integrated heat spreader (IHS).

• DDR3 — Double Data Rate 3 synchronous dynamic random access memory
(SDRAM) is the name of the new DDR memory standard that is being developed as
the successor to DDR2 SDRAM.

• Enhanced Intel SpeedStep Technology — Enhanced Intel SpeedStep
Technology allows the operating system to reduce power consumption when
performance is not needed.
performance is not needed.
• Intel Turbo Boost Technology — Intel Turbo Boost Technology is a way to
automatically run the processor core faster than the marked frequency if the part is
operating under power, temperature, and current specifications limits of the
Thermal Design Power (TDP). This results in increased performance of both single
and multi-threaded applications.

and multi-threaded applications.
• Execute Disable Bit — Execute Disable 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 over run vulnerabilities and can thus help improve the overall
security of the system. See the Intel
