The first group here is Dell server memory: DDR4 modules in 16GB and 32GB sizes, including Dell-Hynix and other RDIMM listings, plus a DDR3L 16GB RDIMM. Each is listed by Dell part number, so match the number you already have against the page title. The second group is complete PowerEdge rack servers in the R-series, from the R240 and R630 through the R640, R740 and R740xd to the R650, R750, R760 and R7525. Memory suited to a particular server is a matter of checking the module type against that server, which the part pages let you do. Related Dell items are in Networking (Dell / EMC).
