Intel Xeon processor 5600 series are based on a low-power microarchitecture that 
supports operation within various C-states. Additionally, six execution cores and power 
management coordination logic are optimized to manage C-state support at both the 
execution core and package levels. An Intel Turbo Boost Technology optimization 
feature is supported on these processors for improved energy efficiency.

Intel

®

 Trusted Execution Technology (Intel

®

 TXT) is also supported and represents a 

set of enhanced hardware components designed to help protect sensitive information 
from software-based attacks. Features include capabilities in the microprocessor, 
chipset, I/O subsystems, and other platform components. When coupled with suitably 
enabled operating systems and applications, Intel TXT helps protect the confidentiality 
and integrity of data in the face of increasingly hostile security environment.

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 voltage 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 5600 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 DDR memory standard, 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.

• 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

Developer's Manuals for more detailed information.

• Functional Operation — Refers to the normal operating conditions in which all 

processor specifications, including DC, AC, signal quality, mechanical, and thermal, 
are satisfied.

• Integrated Memory Controller (IMC) — This is a memory controller that is 

integrated in the processor die. Intel Xeon processor 5600 series can support up to 
3 channels of DDR3, DDR3L memory, with up to 3 DIMMs per channel. Please refer 
to Intel Plan of Record for supported DIMM types, densities and configurations.

• Intel

 Turbo Boost Technology - A way to automatically run the processor core 

faster than the marked frequency if the part is operating under power, 
temperature, and current specification limits of the Thermal Design Power (TDP). 
This results in increased performance of both single and multi-threaded 
applications.

• Intel

 Trusted Execution Technology - A highly versatile set of hardware 

extensions to Intel processors and chipsets that, with appropriate software, 
enhance the platform security capabilities.
