DIMMs

Custom designed by HP, each DIMM contains 36 x 4 SDRAM memory components similar to
PC-133 memory, but qualified to run at 125 MHz. They have a low-voltage TTL interface. The
CEC does not support traditional DRAMs.
The HP 9000 rp7420 server supports DIMMs with 256 MB, 512, MB, 1 GB, and 2 GB capacity.
Table 1-3shows each DIMM supported with its associated capacity, the resulting total system
capacity, and the memory component density.
DIMMs must be loaded in sets of two at specific locations. For best performance, HP recommends
loading sets of eight DIMMs.
