This 32GB DDR5 Registered DIMM (RDIMM) from Samsung, running at 6400MHz configured as 2Rx8, running at CAS latency CL52. As a Registered DIMM (RDIMM), it is a server-class module — the on-module register buffers the command/address signal, which reduces electrical load and lets a server motherboard reliably support many densely-populated DIMM slots, but it requires a server/workstation platform whose memory controller specifically supports registered memory, and will not work in a typical desktop board. Matching capacity, speed, and form factor exactly to the target system (and, for a multi-module upgrade, matching modules to each other) is what lets DDR5 memory run reliably at its full rated speed rather than falling back to a slower, auto-negotiated speed or failing to POST altogether. It ships with ECC protection with the register that defines RDIMM memory. This capacity and speed combination suits current-generation server and workstation platforms that support DDR5-6400 registered ECC memory, offering a mainstream per-module capacity for populating multiple memory channels. It ships with the standard manufacturer warranty and is aimed at builders, upgraders, and IT professionals in South Africa who need accurate specifications to match against their existing platform.
