Dell PowerEdge R230 - Sample Memory Configurations

• When mixing memory modules with dierent capacities, populate the sockets with memory modules with the highest capacity rst. For
example, if you want to mix 4 GB and 8 GB DIMMs, populate 8 GB DIMMs in the sockets with white release levers and 4 GB DIMMs in
the sockets with black release levers.
• Memory modules of dierent capacities can be mixed provided other memory population rules are followed (for example, 4 GB and 8
GB memory modules can be mixed).
• Mixing of more than two DIMM capacities in a system is not supported.
• Populate two DIMMs per processor (one DIMM per channel) at a time to maximize performance.
Sample memory congurations
The following table shows sample memory congurations for a single processor conguration.
NOTE: 1R and 2R in the following table indicate single and dual-rank memory modules respectively.
