2. 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. Please
note this differs from the VID employed by the processor during a power management event (Adaptive
Thermal Monitor, Enhanced Intel SpeedStep
®
Technology, or Low Power States).

3. The voltage specification requirements are measured across VCC_SENSE and VSS_SENSE lands at the
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 into the oscilloscope probe.
4. Refer to Table 2-8
and Figure 2-3 for the minimum, typical, and maximum VCC allowed for a given current.
The processor should not be subjected to any V
