DIMM Population Rules
The DIMM population rules for the server are as follows:
■
In dual-processor systems, all DIMM sockets can have either a DIMM or DIMM
filler panel installed.
Note – In dual-processor systems, DIMM filler panels are not required in sockets
that do not have DIMMs installed.
■
In single-processor systems, all DIMM sockets associated with processor 0 (P0)
socket can have either a DIMM or DIMM filler panel installed. DIMM sockets
associated with processor 1 (P1) socket must remain empty, that is, neither DIMMs
nor DIMM filler panel should be installed.
Note –
In single-processor systems, DIMM filler panels are not required in sockets
that do not have DIMMs installed.
■
A single DIMM configuration is supported.
■
Do not populate DIMM sockets next to an empty processor socket. Each processor
contains a separate memory controller.
