NEMIX RAM 16GB DDR5 4800 CL40 1Rx8 1.1V ECC RDIMM Supermicro H13DSH memory upgrade

Exact-match DDR5-4800 RDIMM for Supermicro H13DSH

This 16 GB registered ECC module runs at 4800 MT/s with CL40 latency and 1.1 V. The 1Rx8 organisation and 288-pin RDIMM form factor match the board's memory-controller requirements so the system recognises the full capacity at rated speed. It is built for servers and workstations that demand error-correcting registered memory.

Upgrading from lower-capacity or slower DDR5 RDIMMs

Adding this module increases total memory bandwidth and capacity while keeping registered ECC integrity across every populated slot. The jump is worth it when your workloads hit the current memory ceiling or when the board's population rules require matched rank and voltage to run all channels at 4800 MT/s. Buyers who need more than 16 GB per slot or who run platforms that accept only unbuffered UDIMMs should look elsewhere.

Limits of the DDR5 RDIMM interface

Registered buffering lets the memory controller drive a full complement of slots, yet the electrical load still caps maximum density per channel. The 4800 MT/s data rate is the baseline DDR5 speed; higher frequencies need explicit motherboard qualification that is not guaranteed here. Systems that require SODIMM or non-ECC UDIMM form factors cannot use this module.
