256GB DDR5 ECC RDIMM kit

This 256GB kit contains two 128GB DDR5 5600 registered DIMMs with ECC and a 4Rx4 organisation. It is built for servers and workstations that require error-correcting memory and registered signal integrity. The modules operate at 1.1V with a CL46 latency. Buyers needing non-ECC or unbuffered memory for consumer platforms cannot use this kit.

Capacity and headroom at 5600 MT/s

The 256GB total capacity provides substantial headroom for virtualisation, in-memory databases and large dataset processing. Each 128GB module uses a 4Rx4 layout to reach this density at the DDR5 5600 (PC5-44800) speed rating. Workloads that exceed 256GB or demand higher frequencies than 5600 MT/s will require additional DIMM slots or faster memory beyond this specification.

Build integration with 288-pin RDIMM slots

Installation requires a motherboard with 288-pin DDR5 RDIMM slots that support registered ECC memory and the 4Rx4 rank configuration. The modules have no heat spreader, so airflow across the DIMMs must be managed by the chassis. This kit frees the builder from mixing capacities or ranks, delivering a matched pair validated for stability under load.

Questions about this item

Can I mix these 288-pin DDR5 5600 RDIMMs with other DDR5 RDIMMs already in my server?

Mixing registered DDR5 modules requires matching speed, voltage and rank configuration; these run at 5600 MT/s, 1.1 V and 4Rx4, so any existing DDR5 RDIMMs must share those specifications.

How can I confirm the kit is running at DDR5 5600 CL46 after installation?

Check the BIOS or a tool such as CPU-Z; you should see each 128 GB module reported at 5600 MT/s with CAS latency 46 and voltage at 1.1 V.

What comes in the MR44800-744K2 box and what must I source separately?

The box contains two 128 GB DDR5 5600 ECC registered RDIMMs (256 GB total); no heat spreaders or cables are included, and a compatible DDR5 RDIMM motherboard is required.
