384GB DDR4 ECC RDIMM Kit

This 384GB kit contains six 64GB DDR4 2666 ECC registered DIMMs built for servers and workstations that require error-correcting memory. The modules run at 1.20V with CL19 latency and use a 2Rx4 organisation. They are intended for IT professionals and system builders who need maximum capacity in a registered configuration.

288-Pin Registered Modules for Compatible Platforms

Each module uses the standard 288-pin RDIMM form factor and presents a registered signal to the memory controller. The kit requires a motherboard that supports DDR4 ECC registered memory and can populate six slots. It frees the builder from mixing capacities or speeds because every stick is identical and validated as a matched set.

384GB Total Capacity with Six Slots Filled

The six 64GB modules deliver 384GB of addressable memory, suitable for virtualisation hosts, database servers and large-scale compute workloads. Capacity scales only by adding more modules of the same specification; the kit itself occupies all six slots in many common server boards, leaving no room for further expansion without removing existing DIMMs.

Questions about this item

What is the sustained thermal limit of the 384GB DDR4 2666 kit when running at 1.20V all day?

The modules operate at 1.20V with no heat spreader, so sustained thermal headroom depends entirely on server chassis airflow across the 288-pin RDIMM slots.

How much fan noise or extra power draw should I expect from six 64GB 2Rx4 RDIMMs under continuous load?

Registered DDR4 RDIMMs add only milliamps per module at 1.20V; any audible noise or measurable power increase comes from the system fans responding to total platform load, not the memory itself.

Which motherboard features must already be present for this 6 x 64GB ECC RDIMM kit to function?

A server or workstation board with six DDR4 RDIMM slots, registered ECC support, and a memory controller qualified for 2Rx4 64GB density at 2666 MT/s is required.
