Electrical Specifications
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.

V
CC
Overshoot
The processor can tolerate short transient overshoot events where V
CC
exceeds the VID
voltage when transitioning from a high to low current load condition. This overshoot
cannot exceed VID + V
OS_MAX
(V
OS_MAX
is the maximum allowable overshoot voltage).
The time duration of the overshoot event must not exceed T
OS_MAX
(T
OS_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.
NOTES:
1.
1.
V
OS
is measured overshoot voltage.
2.
T
OS
is measured time duration above VID.
