Identify and Remove a Failed DIMM
Note - In single-processor servers, the DIMM sockets associated with the processor 1 (P 1)
are nonfunctional and should not be populated with DIMMs. In single-processor servers, a
maximum of 8 DIMMs are supported and the DIMMs must be installed in DIMM sockets
associated with the P0 processor socket.
The population rules for adding DIMMs to the server are as follows:
■
The server supports 64-GB DDR4-2400 DIMMs, 32-GB DDR4-2400 DIMMs, and 16-GB
DDR4-2400 DIMMs.
■
There are two supported memory configurations: 4 DIMMs per CPU or 8 DIMMs per CPU.
■
Do not mix DIMM sizes.
■
Within a memory channel, DIMMs must be populated in the white sockets first, then in the
black sockets.
