Server memory kit

This NEMIX RAM kit delivers 32 GB of DDR5 4800 registered ECC memory in a matched pair of 16 GB modules. It is built for Supermicro GPU SuperServer models such as the SYS-821GE-TNHR, SYS-821GV-TNR and SYS-421GE-TNRT.

ECC and registered operation

The modules run at 1.1 V with a CAS latency of 40 and use a 1Rx8 organisation. ECC and registered buffering protect data integrity and reduce electrical load on the server memory controller.

288-pin RDIMM installation

Each stick fits a standard 288-pin DDR5 RDIMM slot; alignment keys prevent mis-insertion. Common issues arise when mixing ranks or speeds across channels, so populate identical slots per the motherboard manual.

Questions sur cet article

Will the 1Rx8 DDR5 RDIMMs need replacement under sustained server load?

The modules are rigorously stress tested under load to ensure reliability for mission‑critical environments.

What limit appears first when running DDR5 4800 at CL40 continuously?

The registered buffer and ECC logic maintain signal integrity at the rated 4800 MT/s, so the JEDEC‑defined speed and latency ceiling is the first bound.

How much heat and power do the 1.1 V modules produce all day?

Each DIMM operates at 1.10 V without a heat spreader, relying on server chassis airflow for thermal management.
