NEMIX RAM
16 GB DDR5-4800 ECC registered RDIMM for Dell servers, CL40 1.1 V operation
This NEMIX RAM module is a 16 GB DDR5 4800 MHz registered ECC DIMM built for Dell servers and workstations. It runs at 1.1 V with CL40 latency and uses a 288-pin form factor. Major OEM chips from Samsung, Micron or Hynix are validated under load for mission-critical stability.
Administrators who need a single 16 GB registered ECC stick for a qualified Dell platform will find this part a direct match. Builders looking for unbuffered non-ECC memory, higher frequencies, lower latencies or consumer desktop DIMMs should select a different module.
The 1Rx8 registered ECC design is the specification that determines compatibility with Dell server motherboards requiring registered DDR5. Verify your system documentation calls for a registered RDIMM before ordering.

Yes, if the existing modules are also DDR5 4800 RDIMMs with ECC and 1.10V voltage, the server can run both together at the shared speed and timing.
Enter the system BIOS or use a tool like CPU-Z to verify the memory operates at 4800 MT/s, shows CL40 timings, and reports ECC registered status.
The box contains only the single 16GB 288-pin DDR5 RDIMM module; no heat spreader or tools are included.
