128 megabytes. See the Sun Enterprise 220R Server Owner’s Guide for more
information about memory.
3.2.1 Configuration Rules
The following memory configuration rules apply to your system:
4
At least one memory bank (all four bank slots) must be filled for the system to
boot.
4
DIMMs must be added four at a time within the same bank.
4
DIMM capacities can differ from one bank to the next—for example, four
64-Mbyte DIMMs installed in bank 0 and four 128-Mbyte DIMMs installed
in bank 2 is permissible.
Refer to the following diagram for memory locations in your system.
