DIMM Layout and Population Rules
The physical layout of the DIMMs and processors is shown in the following figure. When viewing the server from the front, processor 0 (P 0) is on the left.
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.
