Single-rank/dual-rank RDIMM modules - 4 CPUs populated (if all modules
have different capacity)
–
Configurations are defined so that the waste for spare-memory is minimized;
performance is not prioritized, in other words channels will be filled with two
modules before populating new channel.
–
If two dif
ferent capacities for rank sparing mode are ordered, populate them
on different CPUs, so that on one CPU is only one type; for example 12
modules ordered (8x 8 GB and 4x 16 GB) then use the type with bigger
capacity modules for CPU 1.
