  • ECC registered design protects data integrity in critical workloads
  • 256GB total capacity across four 64GB modules scales server memory
  • DDR5 5600 speed with CL46 latency delivers high-throughput performance
  • 1V operating voltage reduces power draw per module
  • JEDEC and RoHS compliant for warranty-safe upgrades

Capacity and Form Factor

This OWC kit supplies 256 GB of DDR5 server memory as four 64 GB registered DIMMs. Each module uses a 288-pin RDIMM form factor with 2Rx4 organisation and runs at 1.1 V. The kit is built for workstations, NAS systems, servers and network switches that require ECC registered memory.

Who Should Buy and Who Should Not

This memory suits administrators upgrading compatible DDR5 platforms that specifically call for registered ECC DIMMs. It will not work in standard desktop PCs, consumer laptops or any system that accepts only unbuffered or load-reduced modules. Builders needing non-ECC memory or a different pin count must choose another product.

Deciding Specification

The modules operate at DDR5 5600 with a CAS latency of CL46 and conform to the PC5-44800 JEDEC standard. Verify that your motherboard or server documentation lists DDR5 5600 registered ECC RDIMM support before purchasing.

Perguntas sobre este artigo

Does this kit fit a 288-pin DDR5 RDIMM slot?

Yes, each module is a 288-pin DDR5 ECC Registered DIMM designed for workstation and server slots.

How do I install the four 64 GB modules correctly?

Populate all four slots in the server's recommended channel order; the common mistake is mixing these registered DIMMs with unbuffered or load-reduced memory.

Will the modules need active cooling later?

No heat spreader is included, so ensure the chassis provides adequate airflow over the bare PCBs for sustained operation.
