DC for a power supply is defined as any variation less than 1 MHz.
±1% tolerance
±1% ripple, ±2% total as measured at VR remote sense point
Unless otherwise noted, all specifications in this table apply to all processors. These specifications are
based on pre-silicon characterization and will be updated as further data becomes available.
Individual processor VID values may be calibrated during manufacturing such that two devices at the same
speed may have different settings.

The V voltage specification requirements are measured across vias on the platform for the VCORESENSE
CC
and VSSCORESENSE pins close to the socket with a 100 MHz bandwidth oscilloscope, 1.5 pF maximum
