Electrical Specifications
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) 10.1 
Design Guide For Desktop and Transportable 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.
