Datasheet, Volume 1

The processor DC specifications in this section are defined at the processor 
pads, unless noted otherwise. See 

 for the processor land listings and 

 for signal definitions. Voltage and current specifications are detailed in

static and transient tolerances. This same information is presented graphically in 

The DC specifications for the DDR3 signals are listed in 

 Control Sideband and 

Test Access Port (TAP) are listed in 

 through 

 list the DC specifications for the processor and are valid 

only while meeting the thermal specifications (as specified in the processor Thermal 
and Mechanical Specifications and Guidelines), clock frequency, and input voltages. 
Care should be taken to read all notes associated with each parameter. 

1.

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).

2.

The voltage specification requirements are measured across VCC_SENSE and VSS_SENSE lands at the 

socket with a 100-MHz bandwidth oscilloscope, 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. 

3.

Refer to 

 and 

 for the minimum, typical, and maximum V

CC

 allowed for a given current. 

The processor should not be subjected to any V

CC

 and I

combination wherein V

CC

 exceeds V

CC_MAX

 for a 

given current.
