Introduction
The Intel
®
 Core™ i7-900 desktop processor Extreme Edition series and Intel
®
 Core™ 
i7-900 desktop processor series are intended for high performance high-end desktop, 
Uni-processor (UP) server, and workstation systems. Several architectural and 
microarchitectural enhancements have been added to this processor including four 
processor cores in the processor package and increased shared cache.
The Intel
®
 Core™ i7-900 desktop processor Extreme Edition series and Intel
®
 Core™ 
i7-900 desktop processor series are the first desktop multi-core processor to 
implement key new technologies:
• Integrated memory controller
• Point-to-point link interface based on Intel QPI
 shows the interfaces used with these new technologies.
Note:
In this document the Intel
®
 Core™ i7-900 desktop processor Extreme Edition series 
and Intel
®
 Core™ i7-900 desktop processor series will be referred to as “the processor.”
Note:
The Intel Core™ i7-900 desktop processor series refers to the Intel Core™ i7-900 
desktop processors i7-960, i7-950, i7-940, i7-930, and i7-920.
Note:
The Intel Core™ i7-900 desktop processor Extreme Edition series refers to the Intel 
Core™ i7-900 desktop processor Extreme Edition i7-975 and i7-965.
The processor is optimized for performance with the power efficiencies of a low-power 
microarchitecture.
This document provides DC electrical specifications, differential signaling specifications, 
pinout and signal definitions, package mechanical specifications and thermal 
requirements, and additional features pertinent to the implementation and operation of 
the processor. For information on register descriptions, refer to the Intel
