Notes:
1. I
CACHE
refers to the current drawn by a single Dual-Core Intel Xeon processor 7100 series cache. The
V
CACHE_MIN
loadline assumes two Dual-Core Intel Xeon processor 7100 series caches are powered off one
VRM and that the second cache is drawing I
CACHE_MAX
= 40A.
2. V
VRM_MAX
and V
VRM_MIN
are VRM voltage regulation requirements measured at the power plane reference
point (the VRM remote-sense point is on the system board, not at the socket.)
2.10.2 V
CC
Overshoot Specification
The Dual-Core Intel Xeon processor 7100 series 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 above VID). These specifications apply to the processor
die voltage as measured across the V
CCSENSE
and V
SSSENSE
pins.
