Intel® Xeon® Processor E5-1600/E5-2600/E5-4600 Product Families

Datasheet Volume One

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:

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.
