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. Long term reliability cannot be assured in conditions above or below Max/Min functional limits.
3. The voltage specification requirements are measured across Vcc

as near as possible to the processor
with an oscilloscope set to 100-MHz bandwidth, 1.5 pF maximum probe capacitance, and 1 M 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. PSx refers to the voltage regulator power state as set by the SVID protocol.

voltage during boot (Vboot)1.05V for a duration of 2 seconds.
6. LL measured at sense points.
7. LL specification values should not be exceeded. If exceeded, power, performance and reliability penalty are expected.
8. Load Line (AC/DC) should be measured by the VRTT tool and programmed accordingly via the BIOS Load Line override setup
options. AC/DC Load Line BIOS programming directly affects operating voltages (AC) and power measurements (DC). A
superior board design with a shallower AC Load Line can improve on power, performance, and thermals compared to boards
designed for POR impedance.
9. For Voltage less than 1V, TOB will be 50 mV.
