For the most part, it is recommended that all DIMMs that are installed be of the same type and size. See the 
following rules for mixing DIMMS.

For 16 GB RDIMMs (UCS-MR-1X161RV-G):

Can only be mixed with 32 GB RDIMMs (UCS-MR-1X322RU-G). If 32 GB RDIMMs 
(UCS-MR-1X322RU-G) are mixed with 16 GB RDIMMs (UCS-MR-1X161RV-G), the total DIMM 
quantity must be even numbers (for example 2,4,6,8,...,48). Sum cannot be greater than 48.

(UCS-MR-1X161RV-G) are mixed with 32 GB RDIMMs (UCS-MR-1X322RU-G), the total DIMM 
quantity must be even numbers (for example 2,4,6,8,...,48). Sum cannot be greater than 48.

For 32 GB LRDIMMs (UCS-ML-1X324RU-G):

Can only be mixed with 64 GB LRDIMMs (UCS-ML-1X644RU-G). If 64 GB LRDIMMs 
(UCS-ML-1X644RU-G) are mixed with 32 GB LRDIMMs (UCS-ML-1X324RU-G), the total DIMM 
quantity must be even numbers (for example 2,4,6,8,...,48). Sum cannot be greater than 48.
