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. Conversely, when VTTPWRGOOD is high, the V

‘_N’ and ‘_P’ after a signal name refers to a differential pair.
Commonly used terms are explained here for clarification:
• Intel® Xeon® Processor 3500 Series — The entire product, including processor
substrate and integrated heat spreader (IHS).
• 1366-land LGA package — The Intel® Xeon® Processor 3500 Series is available
in a Flip-Chip Land Grid Array (FC-LGA) package, consisting of the processor
mounted on a land grid array substrate with an integrated heat spreader (IHS).
mounted on a land grid array substrate with an integrated heat spreader (IHS).
• LGA1366 Socket — The processor (in the LGA 1366 package) mates with the
system board through this surface mount, 1366-contact socket.
• 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 SRDRAM.

performance is not needed.
• 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 overrun vulnerabilities and can thus help improve the overall
security of the system. See the Intel
