NOTES:
1.
The loadline specification includes both static and transient limits except for overshoot
allowed as shown in Section 2.6.3.
2.
3.
This loadline specification shows the deviation from the VID set point.
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 Design
Guide For Desktop and Transportable LGA775 for socket loadline guidelines and VR
implementation details.
2.6.3
VCC Overshoot
The processor can tolerate short transient overshoot events where VCC exceeds the VID
voltage when transitioning from a high to low current load condition. This overshoot
cannot exceed VID + VOS_MAX (VOS_MAX is the maximum allowable overshoot voltage).
The time duration of the overshoot event must not exceed TOS_MAX (TOS_MAX is the
maximum allowable time duration above VID). These specifications apply to the
processor die voltage as measured across the VCC_SENSE and VSS_SENSE lands.
