Memory Board/Memory-Module Kits Notes The server uses 60 ns, 168-pin, error correction code (ECC), dual inline memory modules (DIMMs). The memory board contains four banks (0-3), arranged in 16 DIMM connectors and supports 4-way memory interleaving. You can install a maximum of 4 GB of memory in the server, with 256 MB memory modules in all 16 connectors (J2 through J17). Each bank contains connectors for four memory modules. The memory-module kit sizes available for the server are 64 MB, 128 MB, and 256 MB. As a minimum, the server requires 1 full bank of memory. To ensure proper server operation, you must maintain 4, 8, 12, or 16 memory modules in the server. All the DIMMs installed in a bank must be the same size, but different banks can have different sized DIMMs J17 Bank 3, Interleave 3 J13 Bank 2, Interleave 3 J9 Bank 1, Interleave 3 J5 Bank 0, Interleave 3 J16 Bank 3, Interleave 2 J12 Bank 2, Interleave 2 J8 Bank 1, Interleave 2 J4 Bank 0, Interleave 2 Bank 3, Interleave 1 J15 Bank 2, Interleave 1 J11 Bank 1, Interleave 1 J7 Bank 0, Interleave 1 J3 Bank 3, Interleave 0 J14 Bank 2, Interleave 0 J10 Bank 1, Interleave 0 J6 Bank 0, Interleave 0 J2 Several examples of memory module configurations are: The base memory is four 64 MB DIMMs. The DIMMs are installed in bank 0, connectors J2-J5. You want four 64 MB DIMMS, eight 128 MB DIMMs, and four 256 MB DIMMs in the server. Leave the 64 MB DIMMS in bank 0, connectors J2-J5 and install the 128 MB DIMMS in bank 1, connectors J6-J9 and bank 2 connectors J10-J13 and the 256 MB DIMMs in bank 3, connectors J14-J17.
