The loadlines specify voltage limits at the die measured at the VCC_SENSE and
VSS_SENSE pins. Voltage regulation feedback for voltage regulator circuits must be
taken from processor VCC and VSS pins. Refer to the Intel(R) IMVP-6 Mobile Processor
Voltage Regulation Specification for socket loadline guidelines and VR implementation
details.

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 pins.
NOTES:
1. V
OS
is measured overshoot voltage.
2. T
OS
is measured time duration above VID.
