Server-grade ECC registered memory kit

This 256GB kit contains eight 32GB DDR4 2133MHz CL15 modules built to JEDEC PC4-17000 specifications. It targets administrators upgrading workstations, servers or NAS systems that require registered ECC RDIMMs for data-integrity workloads.

Registered ECC RDIMM form factor

The modules are 288-pin DDR4 RDIMMs with 2Rx4 organisation and on-die ECC. Standard desktop motherboards cannot use registered memory, and mixing these with unbuffered DIMMs will prevent the system from posting.

Straightforward DIMM installation

Installation follows the usual DIMM-slot procedure: align the notch, press until the latches click, and populate slots per the platform’s channel guide. The most common issue is attempting to install these in a consumer board that only accepts unbuffered non-ECC memory.
