Server memory kit

This OWC kit supplies 256 GB of DDR5 ECC registered memory across eight 32 GB RDIMMs. It targets workstations, servers, NAS systems and network switches that require registered error-correcting modules. Standard desktop platforms cannot use this memory.

Installation notes

Modules use the standard 288-pin DDR5 form factor and operate at 1.1 V. The kit is a dual-channel configuration; populate slots according to the system manual. Mixing with unbuffered or load-reduced ECC DIMMs is not supported and will prevent boot.

Capacity and limits

Eight ranks of 2Rx4 organisation deliver 256 GB total, suitable for virtualisation, large databases and memory-intensive workloads. The CL46 latency at 5600 MT/s meets JEDEC PC5-44800 specifications. Workloads exceeding 256 GB or requiring unbuffered memory need a different solution.

Questions about this item

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

Check the BIOS or a system utility such as CPU-Z; each of the eight 32 GB modules should report 5600 MT/s, CL46 timings, 1.1 V operation and registered ECC status.

What ships in the box and what must be sourced separately?

The package contains eight 32 GB DDR5 5600 CL46 2Rx4 288-pin registered ECC RDIMMs; no heat spreaders, cables or additional components are included.

Which capacity or version of this kit should I choose for my server?

This single SKU delivers 256 GB total via eight 32 GB registered ECC modules; select it only if your workstation or server requires registered DDR5 RDIMMs and supports 256 GB in an eight-slot configuration.
