384GB DDR5 ECC RDIMM kit for Supermicro servers

This 384GB kit contains twelve 32GB DDR5 4800 registered DIMMs with ECC and a CAS latency of CL40. It is built for Supermicro Storage SuperServer models SSG-521E-E1CR24H, SSG-521E-E1CR24L and X13SEDW that require registered memory. The modules operate at 1.1V and use a 1Rx4 organisation.

Registered ECC modules with 1Rx4 layout

Registered buffering and on-die ECC protect data integrity in multi-socket server workloads. The 1Rx4 rank structure lets the memory controller address all twelve modules efficiently across the supported Supermicro platforms. No heat spreaders are fitted, so airflow in the server chassis handles cooling.

Verify slot count and qualified vendor list

Confirm the target server has twelve free DDR5 RDIMM slots and that the system BIOS supports 384GB total capacity with 1Rx4 modules. Cross-reference the part number MR38400-314K12 against the Supermicro qualified vendor list for the exact model before ordering.

Questions about this item

Will the twelve 1Rx4 DDR5 RDIMMs need any firmware updates or periodic reseating during their service life?

No firmware updates are required for these registered DIMMs; they are validated for the Supermicro Storage SuperServer SSG-521E-E1CR24H and SSG-521E-E1CR24L platforms and only need reseating if the system is physically moved.

What limit appears first when the kit runs at DDR5 4800 CL40 continuously — thermal throttling or memory-controller bandwidth?

The memory controller on the X13SEDW platform reaches its sustained bandwidth ceiling before the passive 1.1V modules hit any thermal limit.

How much extra heat and fan noise do the twelve 288-pin registered modules add when the server runs 24/7?

The 1.1V RDIMMs operate without heat spreaders and contribute minimal thermal load; system fan speed remains governed by CPU and chassis sensors, not by the memory kit.
