NOTES:
1. Unless otherwise noted, all specifications in this table are based on estimates and simulations or empirical data.
These specifications will be updated with characterized data from silicon measurements at a later date.
2. Adherence to the voltage specifications for the processor are required to ensure reliable processor operation.
VID Range VID 0.8500 — 1.5 V

3. 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 this differs
from the VID employed by the processor during a power management event (Thermal Monitor 2, Enhanced Intel
SpeedStep
®
technology, or Extended HALT State).

4. These voltages are targets only. A variable voltage source should exist on systems in the event that a different
voltage is required. See
Section 2.3 and Table 2 for more information.
5. 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.
6. Refer to Table 6 and Figure 1 for the minimum, typical, and maximum V
CC
allowed for a given current. The
processor should not be subjected to any V
CC
and I
CC
combination wherein V
CC
exceeds V

for a given
current.
