Server Hardware Configuration
NVDIMM-Ns are currently supported in the T640, R640,R740/R740XD, R840, R940, R940xa, MX740c and MX840c PowerEdge
Servers. Each server supports from 1x to a maximum of 12x 16GB NVDIMM-Ns for a total max persistent memory capacity of
192GB. Table 1 below provides the NVDIMM-N configurations that have been validated and are fully supported for 2-Socket
server configurations. For 4-Socket configurations in the R840, R940, R940xa and MX840c PowerEdge Server, NVDIMM-Ns
are only supported in CPU 1 and CPU 2 memory slots. Table 2 below provides the NVDIMM-N configurations that have been
validated and are fully supported on the R840, R940, R940xa and MX840c 4-Socket configurations.
Refer to Figure 5 for the R740/R740XD CPU and DIMM slot locations as an example. Please see the respective server’s
Installation and Service Manual for memory installation guidelines.
