Note Each RSP8 DIMM socket has one plastic lever on one end, which is used to remove the DIMM from its socket.

Caution To prevent memory problems, DRAM DIMMS must be 3.3V devices. Do not attempt to install higher-voltage devices (such as those designed for the RSP2) in the RSP8 DIMM sockets.

Table 9-2lists the various configurations of DRAM DIMMs that are available for the RSP4 and

Table 9-3lists the various configurations of DRAM DIMMs that are available for the RSP8. These tables also provide the number of DIMMs for each configuration, and the DRAM banks they occupy. Note which banks are used given the combinations of available DIMM sizes and the maximum DRAM you require.
