Server memory kit

This NEMIX RAM kit provides 128GB of DDR5 ECC RDIMM capacity in two 64GB modules. It is built for servers and workstations that require registered, error-correcting memory for data integrity.

Registered ECC at 4800 MT/s

The decisive specification is the combination of registered ECC operation and a 4800 MT/s data rate with CL40 latency. Only systems designed for DDR5 RDIMM modules can use this memory.

Dual-module population

The two-module kit fills a matched pair of slots on a compatible DDR5 server motherboard, leaving remaining channels open for further expansion. It operates at 1.10V without a heat spreader, relying on system airflow for cooling.

Questions about this item

What does the 4800 MT/s rating mean when the kit is installed in a server?

The modules run at 4800 MT/s, delivering PC5-38400 bandwidth, provided the platform supports that data rate.

How does the 288-pin DDR5 RDIMM interface limit real-world performance?

The registered DDR5 interface caps throughput at the rated 4800 MT/s and adds one cycle of address latency for signal integrity.

What physical space and slot type are required to fit these two 64 GB modules?

Two standard 288-pin DDR5 RDIMM slots are needed; the modules have no heat spreader, so they fit in tight server DIMM rows.
