Notes on Rank Sparing mode
– Same numbers mean identical modules (capacity, rank)
– In case of Single-/Dual-Rank memory configurations, at least two 1R or 2R
modules must be populated per a channel.
– In case of Quad-Rank memory modules, please note the following: Due to
performance reasons, always populate a new channel before installing the
3rd memory slot of a channel.
– Only one memory module capacity per CPU is allowed.
If two different memory module capacities have been ordered for Rank
Sparing mode, populate them on different CPUs, so that each CPUs only
comprises modules of one capacity
Example:
12 modules have been ordered, 8 x 4 GB and 4 x 8 GB.
In this case, proceed as follows:
Ê
Use the capacity group with more memory modules for CPU 1 and
populate them according to the population sequence for mono CPU
configurations.
Ê
Populate the other capacity group on CPU 2 according to the population
rules for mono CPU configurations.
