64GB DDR5 4800 ECC Registered RDIMM

This NEMIX RAM module provides 64GB of DDR5 server memory rated at 4800MHz with a PC5-38400 designation. It operates at 1.1V with a CAS latency of 40 and uses a 2Rx4 rank configuration. The 288-pin registered DIMM includes on-die ECC for data integrity in enterprise environments.

Suited for DDR5 servers needing registered ECC

This module fits servers that require DDR5 4800MHz registered RDIMMs with ECC functionality. It is not for desktop PCs or workstations that accept only unbuffered UDIMMs. Builders needing non-ECC memory or lower-density modules should look at alternative configurations.

Registered RDIMM form factor with ECC

The 288-pin registered design with ECC support is the single specification that determines compatibility. Systems must support DDR5 registered memory with error correction to use this module. Unbuffered or non-ECC platforms will not accept this RDIMM.

Questions about this item

How can I verify the 64GB DDR5 4800 module is running at PC5-38400 with CL40 after installation?

Check the BIOS or UEFI memory information screen; it should report 4800 MT/s, CAS latency 40, 1.1 V operation and ECC registered status for the installed 64GB DIMM.

What is included with the 288-pin ECC RDIMM and what must be sourced separately?

The box contains one 64GB DDR5 4800 2Rx4 registered DIMM; no cables, brackets or additional memory modules are supplied.

Which NEMIX RAM DDR5 4800 version should I select for a server needing a single 64GB 2Rx4 registered stick?

Choose the 64GB PC5-38400 CL40 1.1 V 288-pin ECC RDIMM (part MR38400-924K1-M321R8GA0BB0-CQK-V27) — it matches those exact specifications.
