This Micron module is a 64GB DDR5 Registered DIMM (RDIMM) stick, running at 5600MHz configured as 2Rx4, 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. This capacity suits mainstream server memory configurations, virtualization hosts, and multi-channel workstation platforms that support registered ECC memory. It is offered through Marvel's component catalog with manufacturer warranty backing, aimed at South African system builders, upgraders, and IT professionals sourcing verified, correctly-specified parts rather than guesswork.
