Voltage Identification
The VID specification for the Intel Xeon processor MP on the 0.13 micron process processor is
supported by the VRM 9.1 DC-DC Converter Design Guidelines. The minimum voltage is
provided in Table 7, and changes with processor frequency. This allows processors running at a
higher frequency to have a relaxed minimum voltage specification. The specifications have been
set such that one voltage regulator design can work with all supported processor frequencies.
Note that the VID pins will drive valid and correct logic levels when the Intel Xeon processor MP
on the 0.13 micron process processor is provided with a valid voltage applied to the SM_VCC pins.
SM_VCC must be correct and stable prior to enabling the output of the VRM that supplies
VCC. Similarly, the output of the VRM must be disabled before SM_VCC becomes invalid.
Refer to Figure 18 for details.
The Intel Xeon processor MP on the 0.13 micron process processor uses five voltage identification
pins, VID[4:0], to support automatic selection of processor voltages. Table 4 specifies the voltage
level corresponding to the state of VID[4:0]. A ‘1’ in this table refers to a high voltage and a ‘0’
refers to low voltage level. If the processor socket is empty (VID[4:0] = 11111), or the VRM cannot
supply the voltage that is requested, this VRM must disable itself. See the VRM 9.1 DC-DC
Converter Design Guidelines.
