512 GB DDR5 RDIMM kit for Supermicro servers

This kit supplies four 128 GB registered DIMMs totalling 512 GB of DDR5 4800 memory. It is built for Supermicro GPU SuperServer models SYS-821GE-TNHR, SYS-821GV-TNR and SYS-421GE-TNRT where ECC registered modules are required.

Registered ECC design with 4Rx4 organisation

Each module uses a 4Rx4 layout at 1.1 V and CL40 latency, delivering error-correcting registered operation without a heat spreader. The 288-pin form factor matches the server motherboard slots specified for these systems.

Suited for IT teams expanding compatible

Buyers needing higher capacities per module or different memory speeds should look elsewhere. This kit is validated only for the listed Supermicro server models and will not fit consumer desktop boards.

Questions sur cet article

Will the 4Rx4 registered DIMMs need any firmware updates or periodic reseating after installation?

The modules are rigorously stress tested under load before shipping and carry a lifetime replacement warranty; no firmware updates or scheduled reseating are required.

What thermal limit appears first when the kit runs at DDR5 4800 continuously in a Supermicro GPU SuperServer?

The registered DDR5 4800 DIMMs operate at 1.10 V without heat spreaders, so the memory controller’s thermal throttle point is reached before the DRAM itself overheats.

How audible are the 288-pin RDIMMs and what is their power draw at 1.1 V during all-day operation?

Solid-state DRAM produces no noise; total power draw is determined by the four 128 GB modules running at the rated 1.1 V DDR5 voltage.
