Registered DIMMs (RDIMMs)
The following notes provide information that you must consider when you install
RDIMMs:
v The memory channels run at the fastest common frequency of the installed
DIMMs.
v Do not use both RDIMMs and UDIMMs in the same server.
v The server supports up to three single-rank, dual-rank, or quad-rank RDIMMs per
channel.
v The RDIMM options that are available for the server are 1 GB, 2 GB, 4 GB, and
8 GB (when available) memory DIMMs.
v You can install a maximum of 32 GB of memory in the server when you use
RDIMMs.
