5.2 Traditional DIMMs with DCPMMs

For mixed memory configurations containing both traditional DIMMs and persistent

memory modules, populating six traditional DIMMs into the first channels slots and six

DCPMMs into the second channels slots will reap the highest memory bandwidth and

lowest memory access latency. The benefits gained from DCPMMs persistence and

increased capacity will offset the memory bandwidth degradation introduced from

having two interleave sets.

Figure 8: When using both DIMMs and DCPMMs, populating the first six slots with identical traditional

DIMMs and the last six slots with identical DCPMMs is recommended. Two interleave sets are created

because DIMMs and DCPMMs are unique drive types. Despite the memory bandwidth degradation that

occurs from having two interleave sets, the persistence and increased capacity gained from DCPMMs

will still enable various potential benefits
