Nomenclature
Errata are design defects or errors. These may cause the Intel

 Processor 
E7-8800/4800/2800 Product Families behavior to deviate from published specifications. 
Hardware and software designed to be used with any given stepping must assume that 
all errata documented for that stepping are present on all devices.
S-Spec Number is a five-digit code used to identify products. Products are 
differentiated by their unique characteristics, for example, core speed, L2 cache size, 
package type, etc. as described in the processor identification information table. Read 
all notes associated with each S-Spec number.
Specification Changes are modifications to the current published specifications. 
These changes will be incorporated in any new release of the specification.
Specification Clarifications describe a specification in greater detail or further 
highlight a specification’s impact to a complex design situation. These clarifications will 
be incorporated in any new release of the specification.
Documentation Changes include typos, errors, or omissions from the current 
published specifications. These will be incorporated in any new release of the 
specification.
Note:
Errata remain in the specification update throughout the product’s life cycle, or until a 
particular stepping is no longer commercially available. Under these circumstances, 
errata removed from the specification update are archived and available upon request. 
Specification changes, specification clarifications and documentation changes are 
removed from the specification update when the appropriate changes are made to the 
appropriate product specification or user documentation (datasheets, manuals, and so 
forth).
