• Populate two DIMMs per processor (one DIMM per channel) at a time to maximize performance.
Sample memory congurations
The following table shows sample memory congurations for a single processor conguration.
NOTE: 1R and 2R in the following table indicate single and dual-rank memory modules respectively.
