WHY CHOOSE THIS PRODUCT?

• HPE 726717-B21 is a straightforward choice when a compatible Gen9 server requires a 4GB registered DDR4 module for replacement or incremental expansion. Its Single Rank x8 design distinguishes it from larger-capacity 8GB, 16GB and 32GB HPE RDIMMs in the same family, making it useful for targeted capacity requirements and spare-parts planning. Before procurement, verify the exact server model and memory population rules, as HPE specifies that different DIMM technologies should not be mixed within a server.
