384GB DDR5 ECC RDIMM kit

This NEMIX RAM kit provides 384GB of DDR5 4800 memory in six 64GB registered DIMMs. It is built for Supermicro SuperWorkstation SYS-551A-T and X13SWA-TF platforms that require ECC RDIMM modules. Each module operates at 1.1V with CL40 latency and a 2Rx4 organisation.

Suited for memory-intensive server workloads

The 384GB capacity supports virtualisation, large databases and scientific computing on compatible Supermicro systems. Builders who need non-ECC memory, lower capacities or different form factors should look at other memory types.

Registered ECC with 2Rx4 organisation

The modules are 288-pin DDR5 RDIMMs with on-die ECC and registered buffering for signal integrity. The 2Rx4 rank structure is required by the target Supermicro platforms for stable operation at the rated speed.

Questions about this item

How much heat and power will the 1.1 V DDR5 RDIMM kit draw running 24/7?

Each 64 GB module operates at 1.10 V without a heat spreader, relying on chassis airflow for cooling; the registered design keeps per-module power low in sustained server workloads.

What must the host system provide for these 288-pin ECC RDIMMs to function?

A Supermicro motherboard with DDR5 RDIMM slots, registered ECC support and a memory controller qualified for 4800 MT/s CL40 2Rx4 modules — the kit is validated for the SYS-551A-T and X13SWA-TF platforms.

Will the 4800 MT/s CL40 2Rx4 modules run reliably beside slower DDR5 RDIMMs already installed?

The memory controller will down-clock all populated channels to the lowest common speed and latency; mixing ranks or speeds is not recommended for stability in registered ECC configurations.
