Server ECC RDIMM upgrade

This OWC kit provides 128 GB of DDR4 ECC Registered memory in a matched pair of 64 GB modules. It is built for workstations and servers that require error-correcting registered DIMMs and will not operate in standard desktop computers or alongside unbuffered memory.

128 GB dual-channel capacity

Two 64 GB sticks run at DDR4 3200 (PC4-25600) with CL22 latency and a 2Rx4 organisation, giving ample headroom for virtualisation, large databases and multi-application workloads. The registered buffer adds a small command-cycle overhead that limits peak bandwidth compared with unbuffered equivalents.

Low-voltage thermal profile

Modules operate at 1.2 V without heat spreaders, relying on chassis airflow for cooling. Power draw stays modest under typical server loads, and the absence of tall heatsinks avoids clearance issues in dense 288-pin DIMM slots.

Questions sur cet article

Will this DDR4 3200MHz CL22 2Rx4 ECC registered kit run alongside my existing DDR4 3200MHz CL22 2Rx4 ECC registered RDIMMs?

Mixing modules of identical speed, latency, rank, voltage and ECC type is the recommended practice; this kit is 3200MHz CL22 2Rx4 at 1.2V and registered.

How can I verify the 128GB dual-channel kit is detected at 3200MHz with ECC active after installation?

Enter the server BIOS or UEFI and confirm total capacity shows 128GB, speed reads 3200MT/s, and ECC status is enabled for each DIMM slot.

Does the package contain only the two 64GB 288-pin RDIMMs, or are any brackets, cables or tools included?

The box holds the two 64GB DDR4 3200MHz PC4-25600 CL22 2Rx4 ECC registered RDIMMs; no heat spreaders, brackets, cables or installation tools are supplied.
