Capacity and Form Factor

NEMIX RAM 64GB DDR5 4800 2Rx4 ECC RDIMM Server Memory is a registered DDR5 module built for enterprise servers and workstations. It delivers 64GB of capacity in a single 288-pin DIMM operating at 4800MT/s with CL40 latency and 1.10V voltage. The 2Rx4 organisation and on-die ECC provide the data integrity required for mission-critical workloads.

Who This Suits and Who Should Look Elsewhere

This module suits IT professionals upgrading or populating DDR5-compatible registered DIMM slots in OEM server platforms from major vendors. It is not for desktop PCs or laptops that accept only unbuffered UDIMMs or SO-DIMMs. Builders needing non-ECC memory, lower voltages than 1.10V, or speeds other than 4800MT/s should select a different part.

Deciding Specification

The registered ECC RDIMM interface with 2Rx4 architecture is the single specification that determines compatibility. Only motherboards designed for registered DDR5 ECC memory can use this module; systems requiring unbuffered or load-reduced DIMMs will not accept it.

Questions about this item

Should I pick the 64 GB 2Rx4 module or look for a different rank layout?

This single 64 GB stick uses a 2Rx4 organisation, which fits servers that accept dual-rank DDR5 RDIMMs and need maximum capacity per slot.

What does the 4800 MT/s rating deliver once the module is installed?

The module runs at DDR5 4800 with CL40 latency, giving 38 400 MB/s peak bandwidth when the platform operates at the rated speed.

How does the 288-pin DDR5 RDIMM interface limit real-world use?

The 288-pin registered ECC design only works in DDR5 server motherboards that support RDIMMs; it cannot be used in desktop UDIMM or SODIMM slots.
