Notes:
1.
These are VID values. Individual processor VID values may be calibrated during manufacturing such
that two devices at the same speed may have different VID settings. Actual voltage supplied to the
processor should be as specified in the load lines in
required to ensure reliable processor operation. Note that this differs from the VID employed by the
processor during a power management event (Thermal Monitor 2 or Extended Halt State).
2.
The voltage specifications are assumed to be measured across V
with a 100 MHz bandwidth oscilloscope, 1.5 pF maximum probe capacitance, and 1-Mohm 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.
3.
Specified at 100 C T
4.
Specified at the VID voltage.
5.
The I
frequencies. Platforms should be designed to this specification.
6.
Based on simulations and averaged over the duration of any change in current. Specified by design/
characterization at nominal V
