This 16GB DDR5 Registered DIMM (RDIMM) from Micron, running at 5600MHz configured as 1Rx8, running at CAS latency CL46. 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. The module uses 16Gbit density dies. A single-rank 16GB module of this kind is a common baseline building block for a server or workstation platform that needs registered ECC memory in smaller per-slot increments than the larger 32GB/64GB/128GB modules elsewhere in this range. 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.
