Server memory upgrade

This OWC module delivers 64GB of DDR4 ECC Registered memory rated at 3200MHz with CL22 latency. It uses a 288-pin RDIMM form factor and operates at 1.2V. The part is designed for servers, workstations and compatible NAS systems that require registered ECC memory. It will not work in standard desktop computers that use unbuffered modules.

Straightforward module installation

Installation follows the usual DIMM slot procedure for registered server memory. The module is a single 64GB stick with no heat spreader, so it fits standard 288-pin slots. The main compatibility risk is mixing this registered ECC memory with unbuffered or load-reduced ECC modules, which the manufacturer highlights as unsupported. Backward compatibility with 2133MHz, 2400MHz, 2666MHz and 2933MHz speeds is stated.

For registered ECC platforms only

This memory suits administrators upgrading or repairing Dell-compatible servers and workstations that require 2Rx4 registered ECC RDIMMs. It is not for standard desktop PCs, laptops or consumer motherboards that accept only unbuffered non-ECC or unbuffered ECC memory. Buyers needing unbuffered modules, load-reduced ECC, or a different capacity should look at other products.
