Datasheet

VID_SELECT

Output

This land is tied high on the processor package and is used by the 
VR to choose the proper VID table. Refer to the Voltage Regulator-
Down (VRD) 11.0 Processor Power Delivery Design Guidelines For 
Desktop LGA775 Socket for more information.

VRDSEL

Input

This input should be left as a no connect in order for the processor 
to boot. The processor will not boot on legacy platforms where this 
land is connected to V

SS

. 

VSS

Input

VSSA provides isolated ground for internal PLLs on previous 
generation processors. 

VSSA

Input

VSSA is the isolated ground for internal PLLs.

VSS_SENSE

Output

VSS_SENSE is an isolated low impedance connection to processor 
core V

SS

. It can be used to sense or measure ground near the 

silicon with little noise.

VSS_MB_
REGULATION

Output

This land is provided as a voltage regulator feedback sense point for 
V

SS

. It is connected internally in the processor package to the sense 

point land V27 as described in the Voltage Regulator-Down (VRD) 
11.0 Processor Power Delivery Design Guidelines For Desktop 
LGA775 Socket.

VTT

Miscellaneous voltage supply.

VTT_OUT_LEFT

VTT_OUT_RIGHT

Output

The VTT_OUT_LEFT and VTT_OUT_RIGHT signals are included to 
provide a voltage supply for some signals that require termination 
to V

TT

 on the motherboard. 

VTT_SEL

Output

The VTT_SEL signal is used to select the correct V

TT

 voltage level for 

the processor. This land is connected internally in the package to 
V

TT

.
