32GB RDIMMs are all 4-rank (quad-rank).
4-rank creates a high memory load on the memory bus.
16GB LRDIMMs vs. 16GB RDIMMs (2-rank) and 16GB HCDIMMs
16GB LRDIMMs do not outperform 16GB RDIMMs (2-rank) at 1 DPC, 2 DPC.
In addition they do not outperform the RDIMM at 3 DPC either. In contrast 16GB HyperCloud outperforms RDIMMs at 3 DPC.
Therefore, at the 16GB level, LRDIMMs:
