Dual-Core Intel® Xeon® Processor 5200 Series Electrical Specifications

The Dual-Core Intel® Xeon® Processor 5200 Series

provides the ability to operate

while transitioning to an adjacent VID and its associated processor core voltage (V

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.

Table 2-12

includes VID step sizes and DC shift ranges. Minimum and maximum

voltages must be maintained as shown in

Table 2-13

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

Table 2-12

and

Table 2-13

. Refer to the Voltage Regulator Module (VRM) and Enterprise

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.
