Installing additional memory The computer comes with double data rate 4 synchronous dynamic random access memory (DDR4-SDRAM) dual inline memory modules (DIMMs). DIMMs The memory sockets on the system board can be populated with up to four industry-standard DIMMs. These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum memory support, you can populate the system board with up to 64 GB of memory configured in a high-performing dual channel mode.
largest amount of memory is spread between the two channels. If one channel will have more memory than the other, the larger amount should be assigned to Channel A. For example, if you are populating the sockets with one 2 GB DIMM, and three 1 GB DIMMs, Channel A should be populated with the 2 GB DIMM and one 1 GB DIMM, and Channel B should be populated with the other two 1 GB DIMMs. With this configuration, 4 GB will run as dual channel and 1 GB will run as single channel.
7. Open both latches of the memory module socket (1), and insert the memory module into the socket (2). NOTE: A memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket. Populate the black DIMM sockets before the white DIMM sockets. For maximum performance, populate the sockets so that the memory capacity is spread as equally as possible between Channel A and Channel B. Refer to Populating DIMM sockets on page 15 for more information. 8.
