NOTES:
1. The loadline specification includes both static and transient limits except for overshoot
allowed as shown in
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) 11.0
Processor Power Delivery Design Guidelines For Desktop LGA775 Socket for socket loadline
guidelines and VR implementation details.
2.6.3 V Overshoot
CC
The processor can tolerate short transient overshoot events where V
voltage when transitioning from a high to low current load condition. This overshoot
cannot exceed VID + V
The time duration of the overshoot event must not exceed T
maximum allowable time duration above VID). These specifications apply to the
processor die voltage as measured across the VCC_SENSE and VSS_SENSE lands.
