Server DDR5 ECC RDIMM kit

This 256 GB kit contains two 128 GB registered DDR5 modules built for server and workstation platforms that require ECC RDIMM memory. Each module uses a 288-pin interface and operates at the standard 1.1 V DDR5 voltage.

Quad-rank 3DS architecture

The 2S2Rx4 organisation stacks four logical ranks per module through 3DS/TSV packaging, letting a two-module kit present eight ranks to the memory controller. This density increases total capacity per channel without adding more DIMM slots.

5600 MT/s throughput headroom

Rated at DDR5 5600 (PC5-44800) with CL46 latency, the kit delivers high bandwidth for virtualisation, database and compute workloads. Systems limited to lower memory speeds or fewer ranks per channel will not be able to use the full capacity or speed.

Questions sur cet article

Will the 128 GB DDR5 modules need any firmware updates or heat-spreader additions later?

The modules have no heat spreader and run at the standard 1.1 V DDR5 voltage; no firmware updates are required for the memory itself.

What is the first limit reached when the 256 GB kit runs at DDR5 5600 continuously?

Sustained operation is limited by the CL46 latency and the quad-rank 3DS architecture, which caps maximum throughput at the rated 5600 MT/s.

How much heat and noise do the two 288-pin RDIMMs produce under all-day load?

With no heat spreader and a low 1.10 V operating voltage, the modules generate minimal heat and add no audible noise beyond the system's own cooling fans.
