Supported Memory

The server supports 64-GB dual-rank Registered DIMMs (RDIMMs). Each server processor supports up to twelve DIMMs, organized into 12 memory channels that contain up to 1 DIMM per channel. The maximum supported memory speed is 3200 MT/s, with total supported memory of 1.5 TB.

The memory configurations, or number of DIMMs per processor supported in the server at any time, are 1, 2, 4, 6, 8, 10, or 12.

Note:

If a DIMM fails, the server uses other DIMMs to continue operating. However, the server will use only the number of remaining DIMMs that meets the next smallest memory configuration. For example, if you have 12 DIMMs in the server and 1 fails, the server will then use 10 of the remaining DIMMs because the next smallest supported memory configuration is 10.
