NOTES:

Each processor is programmed with a maximum valid voltage identification value (VID), which is set at

manufacturing and can not 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. Note that this differs from the VID employed by the processor during a power management event

(Thermal Monitor 2, Enhanced Intel SpeedStep technology, or Enhanced Halt State). Typical AVID range is

0.8 V to 0.85 V.

The voltage specifications are assumed to be measured across VCC_SENSE and VSS_SENSE pins at socket

with a 100-MHz bandwidth oscilloscope, 1.5-pF maximum probe capacitance, and 1-MΩ minimum
