High-capacity DDR5 server kit

This NEMIX RAM kit delivers 384 GB of DDR5 memory across twelve 32 GB modules. It is built for enterprise servers and workstations that run virtualisation, large databases or memory-intensive analytics. The registered ECC design adds error correction and signal buffering for stable operation in multi-socket platforms.

Sustained-load behaviour

Each module operates at 5600 MT/s with a CAS latency of CL46 and a low 1.10 V supply. The 2Rx4 organisation spreads accesses across two ranks per DIMM, helping maintain throughput during prolonged compute jobs. Registered buffering reduces electrical load on the memory controller, supporting consistent performance when all twelve slots are populated.

Upgrade context

The kit replaces smaller DDR5 RDIMM sets or mixed-capacity configurations that limit total system memory. It is not suited for desktop boards that accept only unbuffered UDIMMs or for platforms restricted to lower maximum capacities. The jump is worthwhile when the workload demands the full 384 GB address space and the motherboard qualifies twelve registered DIMMs.

Questions about this item

How much power do the twelve 32 GB DDR5 5600 registered ECC modules draw at the rated 1.1 V?

Each module operates at 1.10 V, so the kit’s total power scales with twelve 2Rx4 RDIMMs running at DDR5 5600 CL46; actual wattage depends on workload and motherboard voltage regulation.

What motherboard features are required to run this 12 x 32 GB DDR5 5600 CL46 ECC RDIMM kit?

The board must provide twelve 288-pin DDR5 RDIMM slots, support registered ECC memory at 5600 MT/s, and accept 2Rx4 modules at 1.10 V.

Will these 5600 CL46 registered ECC modules down-clock if installed alongside slower DDR5 RDIMMs already in the server?

Yes, the memory controller will negotiate a common speed and latency; all modules then run at the lowest supported frequency and timing across the populated slots.
