Electrical Specifications

Table 2-9. VCC Static and Transient Tolerance for 775_VR_CONFIG_04A Processors

ICC (A)

Voltage Deviation from VID Setting (V)1, 2, 3, 4

NOTES:

The loadline specification includes both static and transient limits except for overshoot allowed as shown in

Section 2.12.

This table is intended to aid in reading discrete points on Figure 2-2.

The loadlines specify voltage limits at the die measured at the VCC_SENSE and VSS_SENSE lands. Voltage

regulation feedback for voltage regulator circuits must be taken from processor VCC and VSS lands. Refer to

the Voltage Regulator Down (VRD) 10.1 Design Guide For Desktop LGA775 Socket for socket loadline guide-

lines and VR implementation details.

Adherence to this loadline specification for the processor is required to ensure reliable processor operation.
