This 64GB DDR4 Registered DIMM (RDIMM) from Kingston, running at 3200MT/s configured as 2Rx4, running at CAS latency CL22. 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 DDR4 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 Micron F-die (Rambus-licensed). At 64GB, this is a substantial-capacity DDR4-generation server module, suited to memory-hungry virtualization hosts or application servers still running on a DDR4 platform. 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.
