9.3 Rules for Populating DIMM Slots
Table 31 shows the supported DIMM population of the 2 ranks supported by the
EP80579. Configurations not shown in Table 31 are not supported. The rank
configurations supported are one or two ranks on a single DIMM or one rank on each of
the two DIMMs. Two ranks in each of the two DIMMs (that is, four ranks) is not
supported.
9.3.1 Supported Rank Configurations
Table 32 shows the supported rank configurations when using two ranks for the single
and dual DIMM.
