NOTES:
1. The loadline specification includes both static and transient limits except for overshoot allowed as shown in Section 2.12.
2. This loadline specification shows the deviation from the VID set point.
3. 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 and Transportable Socket 775 for socket loadline guidelines and VR implemen-
tation details.
4. Adherence to this loadline specification for the processor is required to ensure reliable processor operation.
