NEMIX RAM DDR5 4800 ECC RDIMM 256GB Kit

This 256GB kit contains eight 32GB DDR5 4800 Registered ECC RDIMMs built for the Supermicro H14SSF motherboard. Each module runs at 1.1V with CL40 latency and a 2Rx8 organisation. The registered buffer lets the memory controller drive every slot at the rated speed without signal degradation.

Ideal for H14SSF servers needing maximum

Administrators populating all DIMM slots on a Supermicro H14SSF board will match the board's population rules exactly. Builders using desktop boards, workstations that require unbuffered UDIMMs, or systems limited to lower densities should look elsewhere.

2Rx8 registered ECC at DDR5 4800 1.1V

The dual-rank 2Rx8 registered ECC design at 1.1V is the single specification that determines whether the H14SSF memory controller will initialise the kit at full 256GB capacity and 4800 MT/s. If your platform requires a different rank structure, voltage or unbuffered modules, this kit will not function.

Perguntas sobre este artigo

Will the Samsung, Micron or Hynix chips on these modules need replacement before the server reaches end of life?

The DRAM chips are rated for continuous server operation and the kit carries a lifetime replacement warranty, so no scheduled chip replacement is expected.

What limits sustained throughput first — the CL40 latency or the 4800 MT/s data rate?

At DDR5-4800 the 4800 MT/s transfer ceiling is reached before CL40 latency becomes the bottleneck in typical server workloads.

How much power do the eight 32 GB registered DIMMs draw at 1.1 V when fully populated?

Eight modules at 1.1 V stay within the DDR5 RDIMM power envelope, and the registered design reduces electrical load on the memory controller during all-day operation.
