2.4.5 Memory requirements and options
375 MHz POWER3 SMP Wide Nodes require two memory cards and a minimum
of 256 MB of memory. These nodes support a maximum of 16 GB of memory;
each card has an 8 GB capacity. Memory is supplied by 128, 256, and 512 MB
DIMMs which must be mounted in pairs. Different capacity DIMM-pairs can be
mixed on the memory cards. Note that with the minimum memory (256 MB)
installed, the second memory card contains no DIMMs. Table 2-6 shows the
memory features for the 375 MHz POWER3 SMP Wide Nodes.
