NOTES:
1.
Unless otherwise noted, all specifications in this table are based on pre-silicon estimates and simulations or
empirical data. These specifications will be updated with characterized data from silicon measurements at
a later date.
2.
Each processor is programmed with a maximum valid voltage identification value (VID), which is set at
manufacturing and cannot be altered. Individual maximum VID values are calibrated during manufacturing
such that two processors at the same frequency may have different settings within the VID range. Please
note this differs from the VID employed by the processor during a power or thermal management event
(Intel Adaptive Thermal Monitor, Enhanced Intel SpeedStep Technology, or Low Power States).
3.
The voltage specification requirements are defined across VCC_SENSE and VSS_SENSE pins on the bottom
side of the baseboard.
