Note:
Devices used on DIMM
The maximum address space supported by the AMD-762 system controller is 4 Gbytes.
Total Memory Sizes
Support of four regist e re d DIMMs is accomplished by the
AMD-762 syst e m con t r olle r ’s eight DDR ch ip -se lect pins
(CS[7:0]#), which allow DIMMs with two ch ip sele ct s 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.
