Figure 2-4 Memory flow diagram for MCM0
The minimum memory for a p5-590 processor-based system is 2 GB and the
maximum installable memory is 1024 GB using DDR1 memory DIMM technology
(128 GB using DDR2 memory DIMM). The total memory depends on the number
of available processor cards. Table 2-1 lists the possible memory configurations.
