Memory Mode and Mixed Mode
The following tables apply to the Memory Mode and Mixed Mode. The recommended DIMM:DCPMM ratio for
Memory Mode is from 1:4 to 1:16. Ratios in that range are indicated in green shading below; ratios outside
that range are indicated in red shading. In Mixed Mode, the ratio is between memory and only the volatile
portion of the DCPMMs and is not specifically called out in the tables below because the ratio depends on
how much of the DCPMM memory has been allocated to volatile memory.
