Memory Capacities for CPU Classes
Mixed DIMM/DCPMM Configurations
This section describes the memory capacities for configurations that use a combination of DIMMS and
DCPMMs.
DIMM/DCPMM Configurations for 2
nd
Generation Intel
®
Xeon
®
Scalable Processors
Table 15, Table 16, and Table 17 show the possible configurations for 2nd Generation Intel® Xeon®
Scalable Processors populated with combinations of DIMMs and DCPMMs. When DCPMMs are selected, there
must be 6 DIMMs per CPU and can be 2, 4, or 6 DCPMMs per CPU, depending on CPU class (“M”, “L”, or
regular class) and DCPMM capacity. Selection of DCPMMs also requires that all CPUs be fully populated. The
tables below show configurations for 1 CPU. For Memory Mode and Mixed Memory Mode, the
Intel-recommended DIMM to DCPMM capacity ratio for the same CPU is from 1:4 to 1:16. The green-shaded
cells of the table indicate ratios within that range, while the red-shaded portions indicate ratios outside
that range. For App Direct Mode, the ratio requirement does not apply.
App Direct Mode
The following tables apply to the App Direct Mode. For App Direct Mode, the DIMM to DCPMM ratio
requirement does not apply.
