Svid Address Usage; Vr12.0 Reference Code Voltage Identification (Vid) Table - Intel Xeon Processor E5-1600 Datasheet

Electrical Specifications
7.1.9.3.6 SVID Voltage Rail Addressing
The processor addresses 4 different voltage rail control segments within VR12 (VCC,
VCCD_01, VCCD_23, and VSA). The SVID data packet contains a 4-bit addressing
code:
Table 7-2.

SVID Address Usage

PWM Address (HEX)
Notes:
1. Check with VR vendors for determining the physical address assignment method for their controllers.
2. VR addressing is assigned on a per voltage rail basis.
3. Dual VR controllers will have two addresses with the lowest order address, always being the higher phase
count.
4. For future platform flexibility, the VR controller should include an address offset, as shown with +1 not
used.
