NOTES:
1. 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. 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 0.75 V to 0.85 V.
2. 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 impedance. The maximum length of ground
wire on the probe should be less than 5 mm. Ensure external noise from the system is
not coupled in the scope probe.
