Intel E5-1600 Svid Voltage Rail Addressing, Svid Address Usage, PWM Address HEX Processor, 159

Electrical Specifications

7.1.9.3.6SVID 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) Processor

00	Vcc
01	Vsa
02	VCCD_01
03	+1 not used
04	VCCD_23
05	+1 not used

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.
