Capacity & Configuration

This kit delivers 384GB of DDR5 server memory across four 96GB registered DIMMs. It targets administrators scaling memory capacity for virtualization, in-memory databases or high-density compute nodes.

Build Integration

Each module uses a 288-pin RDIMM form factor with registered buffering and on-die ECC, requiring a server platform that supports DDR5 6400 registered memory. The four-module layout occupies four DIMM slots and leaves remaining channels free for further expansion.

Sustained Operation

Rated at 6400 MT/s with CAS latency 52 and 1.1 V operation, the modules maintain specified throughput under continuous server workloads. The registered design reduces electrical load on the memory controller, helping stability during prolonged, multi-threaded tasks.

Questions about this item

What CAS latency will the kit run at under sustained server workloads?

The modules are rated at CL52, so sustained operation will use that latency figure.

How much heat and power should I expect from four 96 GB RDIMMs running 24/7?

Each module operates at 1.1 V, keeping total power draw low and heat output modest for continuous server use.

What motherboard slots and CPU memory controller are required for this 288-pin DDR5 ECC registered kit?

You need a server board with DDR5 288-pin RDIMM slots and a CPU that supports registered ECC memory at 6400 MT/s.
