Table 3-1 and Table 3-2 show sample memory configurations that follow the
appropriate memory guidelines stated in this section. The samples show
identical memory-module configurations and their the physical and available
memory totals. The tables do not show mixed or quad-rank memory-module
configurations, nor do they address the memory speed considerations of any
configuration.
NOTE: 8-GB DIMMS are only supported on systems with hot-swappable
hard drives.
