Note: The maximum address space supported by the AMD-762 system controller is 4 Gbytes.
Support of four registered DIMMs is accomplished by the
AMD-762 system controller’s eight DDR chip-select pins
(CS[7:0]#), which allow DIMMs with two chip selects as
illustrated in Figure 5 on page 12. In this example, each DIMM
contains two physical DRAM banks, thus two chip selects are
routed to the DIMM. The AMD-762 system controller provides
one differential clock pair for each registered DIMM.
