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) 10.0 Design Guidelines and Voltage Regulator Module (VRM) and Enterprise
Voltage Regulator Down (EVRD) 10.1 Design Guidelines for socket loadline guidelines and VR implementation.

Overshoot Specification
The Intel® Xeon™ processor with 800 MHz system bus 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.
