Intel® Xeon® Processors 5500 Series Electrical Specifications
The Intel Xeon Processor 5500 Series
 
provides the ability to operate while transitioning 
to an adjacent VID and its associated processor core voltage (V
CC
). This is represented 
by a DC shift in the loadline. It should be noted that a low-to-high or high-to-low 
voltage state change may result in as many VID transitions as necessary to reach the 
target core voltage. Transitions above the maximum specified VID are not permitted. 
 includes VID step sizes and DC shift ranges. Minimum and maximum voltages 
.
The VRM or EVRD utilized must be capable of regulating its output to the value defined 
by the new VID. DC specifications for dynamic VID transitions are included in 
 
and 
Power source characteristics must be guaranteed to be stable whenever the supply to 
the voltage regulator is stable.
