Server-grade DDR5 module

This NEMIX RAM module provides 24GB of DDR5 memory rated at 6400MHz PC5-51200 with ECC and registered operation. It is built for servers and workstations that require error-correcting, buffered DIMMs running at 1.1V. The 288-pin RDIMM form factor fits compatible enterprise platforms only. It is not suitable for standard desktop or laptop computers.

Upgrading from slower DDR5 or smaller capacity

The jump to 6400MHz with CAS latency 52 benefits workloads that move large datasets through memory bandwidth-limited paths. Adding a 24GB 2Rx8 module increases total capacity while maintaining registered signal integrity for multi-DIMM configurations. The upgrade is worth it when your platform supports DDR5 6400 registered ECC and the application scales with both bandwidth and capacity.

Sustained load behaviour

Registered buffering and on-die ECC keep data integrity stable during continuous read-write cycles typical of virtualization, database or compute clusters. The 1.1V operating voltage helps limit thermal output per module under prolonged utilisation. Performance remains consistent as long as the server chassis provides adequate airflow for the memory subsystem.

Questions about this item

Does the 288-PIN DDR5 RDIMM fit a standard server DIMM slot?

The module uses the 288-PIN DDR5 RDIMM form factor, which matches standard registered server DIMM sockets.

What BIOS setting is often missed when installing this 6400MHz ECC RDIMM?

Enable the DDR5 6400 speed profile in BIOS; otherwise the module may default to a lower JEDEC frequency.

How do I know when the Samsung, Micron or Hynix chips on this 24GB kit need replacement?

Run periodic memory diagnostics; uncorrectable ECC errors logged by the OS indicate a module should be swapped.
