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.
Table 2-12
includes VID step sizes and DC shift ranges. Minimum and maximum
voltages must be maintained as shown in
Table 2-13
and
Table 2-2
.
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 2-14
. 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.
