Memory modules installed in memory module sockets with white release levers must be identical and the same rule applies for sockets
with black and green release tabs. This ensures that identical memory modules are installed in matched pairs—for example, A1 with A2,
A3 with A4, A5 with A6, and so on.

Sample memory configurations
The following tables show sample memory configurations for one and two processor configurations that follow the appropriate memory
guidelines stated in this section.
NOTE:
16 GB quad-rank RDIMMs are not supported.
NOTE:
1R, 2R and 4R in the following tables indicate single-, dual-, and quad-rank DIMMs respectively.
