Capacity and kit format

This OWC kit delivers 256GB of DDR5 server memory across eight 32GB modules. It is built for workstations, NAS systems, servers and network switches that require registered ECC DIMMs.

Registered ECC requirement

The modules are 288-pin DDR5 5200 RDIMMs with CL42 latency, 2Rx4 organisation and 1.1V operation. They will not work in standard desktop boards and cannot be mixed with unbuffered or load-reduced ECC memory.

Build integration

Populating eight slots frees no additional bays but provides the full kit capacity in a single validated set. The memory is JEDEC-standard and ROHS-compliant for warranty-safe deployment in qualified platforms.

Points forts

Questions sur cet article

How does the 5200 MT/s speed translate when the kit is installed in a server?

The modules run at the JEDEC-standard 5200 MT/s rate with CL42 latency, delivering the rated PC5-41600 bandwidth as long as the platform supports DDR5-5200 registered ECC memory.

What does the PC5-41600 designation cap in practice?

PC5-41600 is the JEDEC peak transfer rate for DDR5-5200; the kit will not exceed that bandwidth, and actual throughput depends on the memory controller and channel population.

Will the 288-pin registered DIMMs fit in a standard 288-pin DDR5 server slot?

Yes, each 32 GB module uses the 288-pin RDIMM form factor with 2Rx4 organisation and requires a socket that accepts registered ECC DDR5 DIMMs.
