Memory upgrades for Dell PowerEdge rack servers: the R-series from 1U single-socket systems to four-socket R960 and R940 servers, and the HS-series designed for cloud service providers. 85 listings (33 DDR5, 47 DDR4, 2 DDR3, 3 DDR2), each matched to Dell's published memory specification for that model.
Several models have more than one listing because Dell supports more than one memory speed across processor generations, for example DDR5 4800MHz and 5600MHz on the R660 and R760. Choose the listing that matches your processors, or the faster module if you plan to upgrade them.
Where a model supports both registered (RDIMM) and load-reduced (LRDIMM) memory, each type has its own listing. Do not mix the two types in one server, and use one module size across each processor's channels.
Not sure of your model? The model name is on the front of the server and on its pull-out information tag, and the Service Tag lookup at Dell Support lists the memory the system shipped with. Each listing is matched to Dell's published memory specification for that model: memory type, speed and module sizes.
