Quad-Core Intel® Xeon® Processor 5400 Series Electrical Specifications
The Quad-Core Intel® Xeon® Processor 5400 Series
provides the ability to operate
while transitioning to an adjacent VID and its associated processor core voltage (V
CC
).
This will represent a DC shift in the load line. 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 specified VID are not permitted.

includes VID step sizes and DC shift ranges. Minimum and maximum
voltages must be maintained as shown in
and
.
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
by the new VID. DC specifications for dynamic VID transitions are included in

Voltage Regulator-Down (EVRD) 11.0 Design Guidelines for further details.
Power source characteristics must be guaranteed to be stable whenever the supply to
the voltage regulator is stable.
