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. Each processor is programmed with a maximum valid voltage identification value (VID) that is set at manufacturing and cannot 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 that 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 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. Processor IA core VR to be designed to electrically support this current.
5. Processor IA core VR to be designed to thermally support this current indefinitely.
6. Long term reliability cannot be assured if tolerance, ripple, and core noise parameters are violated.
7. Long term reliability cannot be assured in conditions above or below Max/Min functional limits.
8. PSx refers to the voltage regulator power state as set by the SVID protocol.
9. N/A
10. LL measured at sense points.
11. Typ column represents Icc
MAX
for commercial application it is NOT a specification - it is a characterization of limited samples using limited set of
benchmarks that can be exceeded.
12. Operating voltage range in steady state.
13. LL specification values should not be exceeded. If exceeded, power, performance and reliability penalty are expected.
14. By Improving Load Line (Lower LL than Datasheet values, and reporting it to BIOS), customers may obtain slightly better performance although
the frequencies will not be changed.
