Voltage Regulator Connector Signals
The VR module consists of three DC-DC converters, Vcore, Vcache, and Vfixed.
Table 2-18 lists all of the signals which are part of the processor package VR output
connector.
Warning:
If the VR cannot supply the voltages requested by the components in the processor
package, then it must disable itself.
Figure 2-4 shows the top view of the processor package power tab. See Table 2-19 for
power tab connector signals.
