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 also be taken from processor VCC_SENSE and
VSS_SENSE lands. Please refer to the appropriate platform design guide for further details on regulator and
decoupling implementations.

Overshoot Specifications
The Intel Xeon Processor 5500 Series can tolerate short transient overshoot events
where V
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 above VID). These specifications apply to the processor die voltage
as measured across the VCC_SENSE and VSS_SENSE lands.
