Intel® Xeon® Processor 7400 Series Datasheet

The following notes apply:

• The processor DC specifications in this section are defined at the processor die and 

not at the package pins unless noted otherwise.

• The notes associated with each parameter are part of the specification for that 

parameter.

• Unless otherwise noted, all specifications in the tables apply to all frequencies and 

cache sizes.

See 

 for the pin signal definitions. Most of the signals on the processor FSB 

are in the AGTL+ signal group. The DC specifications for these signals are listed in 

.

 through 

 list the DC specifications and are valid only while meeting 

specifications for case temperature (Tcase as specified in 

), clock frequency, 

and input voltages.

The Flexible Motherboard (FMB) guidelines are estimates of the maximum values the 
Intel® Xeon® Processor 7400 Series will have over certain time periods. The values 
are only estimates and actual specifications for future processors may differ. Processors 
may or may not have specifications equal to the FMB value in the foreseeable future. 
System designers should meet the FMB values to ensure their systems will be 
compatible with future processors.
