Processor DC Specifications
The following notes apply:
• The processor DC specifications in this section are defined at the processor core
silicon 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.
• Unless otherwise noted, all the specifications in the tables are based on estimates
and simulations. These specifications will be updated with characterized data from
silicon measurements at a later date.

Flexible Motherboard (FMB) Guidelines
The FMB guidelines are estimates of the maximum values that the Dual-Core Intel Xeon
processor 7100 series processor will have over certain time periods. The values are
only estimates as actual specifications for future processors may differ. The Dual-Core
Intel Xeon processor 7100 series may or may not have specifications equal to the FMB
value in the foreseeable future. System designers should meet the FMB values to
ensure that their systems will be compatible with future releases of the Dual-Core Intel
Xeon processor 7100 series.
