Server Workstation Memory Kit

This OWC kit supplies 256 GB of DDR5 ECC registered memory across four 64 GB modules. It is built for workstations, NAS systems, servers and network switches that require registered DIMMs with error correction.

Verify Platform Compatibility

Your motherboard must support 288-pin DDR5 RDIMMs at 1.1 V and accept 2Rx4 registered modules. This memory will not work in standard desktop boards and cannot be mixed with unbuffered or load-reduced ECC DIMMs.

Build Integration Notes

The four-module kit populates dual-channel configurations in compatible servers. No heat spreaders are included, so ensure your chassis airflow meets the platform's thermal requirements for registered memory.

Questions sur cet article

Does the kit contain everything needed for installation or are extra components required?

The kit includes four 64 GB DDR5 5200 CL42 2Rx4 288-pin 1.1 V ECC registered RDIMM modules; no additional memory parts are required for a full 256 GB upgrade.

How do I decide between the available capacity options for this server memory?

This kit provides 256 GB total in a matched set of four 64 GB modules; choose it when your workstation or server needs that exact capacity and your board supports quad-channel population.

What does the 5200 MT/s rating mean for actual system performance?

The modules run at DDR5 5200 (PC5-41600) with CL42 latency, delivering JEDEC-standard bandwidth and error correction for compatible workstations, NAS units and servers.
