NOTES:
1. The V
CC_MIN
and V
CC_MAX
loadlines represent static and transient limits.
2. The V

and V

loadlines are plots of the discrete point found in
3. Refer to
for processor VID information.
4. The loadlines specify voltage limits at the die measured at the VCCSENSE and VSSSENSE pins. Voltage
regulation feedback for voltage regulator circuits must be taken from processor V
CC
and V
SS
pins. Refer to
the Voltage Regulator Module (VRM) and Enterprise Voltage Regulator-Down (EVRD) 10.2 Design
Guidelines for socket loadline guidelines and VR implementation.

Vcc Overshoot Specification
The Dual-Core Intel Xeon processor 7000 series processor can tolerate short transient overshoot
events where V
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 above VID). These specifications apply to the processor die voltage as measured across
the VCCSENSE and VSSSENSE pins.
