Capacity and configuration

This kit provides 512GB of DDR5 memory arranged as sixteen 32GB modules. It is built for Supermicro servers and workstations that require registered ECC RDIMM modules for data integrity and maximum density.

Registered ECC headroom

The 1Rx4 organisation and CL40 latency at 4800 MT/s give ample bandwidth for virtualisation, large databases and memory-intensive compute workloads. Capacity limits are reached only when the platform's maximum DIMM slots or memory-controller ceiling is exceeded.

Thermals and power

Modules operate at 1.10V without heat spreaders, relying on chassis airflow for cooling. Registered buffering adds minimal latency while keeping per-module power draw low enough for dense 16-DIMM configurations in standard server enclosures.

Questions about this item

Will these 1Rx4 CL40 288-pin DDR5 4800 modules mix with my existing DDR5 4800 ECC RDIMM?

All sixteen modules are 1Rx4 CL40 1.1 V DDR5 4800 registered DIMMs; matching rank, latency, voltage and speed avoids timing conflicts.

How do I confirm the 512 GB kit is detected at full speed on my Supermicro SSG-521E-E1CR24H?

Enter BIOS and verify all sixteen 32 GB modules show as DDR5 4800 with ECC active.

Does the MR38400-314K16 package include anything besides the sixteen 32 GB RDIMMs?

The box contains only the sixteen 288-pin DDR5 4800 ECC registered modules; no cables, tools or heat spreaders are supplied.
