NOTES:
1. Unless otherwise noted, all specifications in this table are based on estimates and simulations or empirical data.
2. Individual processor VID values may be calibrated during manufacturing such that two devices at the same speed may have
different VID settings.
3. These voltages are targets only. A variable voltage source should exist on systems in the event that a different voltage is re-
quired. See Section 2.3
4. The voltage specification requirements are measured across VCC_SENSE and VSS_SENSE pins 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 oscillo-
scope probe.
5. Refer to Table 10/Figure 2
processor should not be subjected to any V
V should never exceed the VID voltage. Failure to adhere to this specification can shorten the processor lifetime.
