Capacity 512GB (8 x 64GB)

  • 512 GB total capacity from eight 64 GB modules
  • DDR4 2666 MHz speed with CL19 latency
  • ECC load-reduced design for server reliability
  • 2 V operation reduces power draw
  • Backward compatible with 2133 and 2400 MHz systems

Server Capacity

This OWC kit delivers 512GB of DDR4 server memory across eight 64GB load-reduced DIMMs. It is built for workstations, servers and NAS systems that require ECC protection and high per-slot density.

Compatibility Scope

The modules suit administrators upgrading JEDEC-compliant DDR4 platforms that accept 288-pin LRDIMMs at 1.2V. They will not work in standard desktop boards that only support unbuffered memory, nor in systems limited to lower maximum module capacities.

Deciding Specification

Each stick is a 4Rx4 ECC LRDIMM rated at 2666MHz CL19, and the kit is backward compatible with 2133MHz and 2400MHz operation. Confirm that your platform supports load-reduced registered DIMMs and 64GB single-module capacity before purchasing.

Preguntas sobre este artículo

Should I pick the 512GB kit or a smaller capacity for my server?

The kit delivers 512GB total using eight 64GB modules, ideal when your workload needs maximum capacity across all populated slots.

What does the 2666MHz rating mean once the modules are installed?

The modules run at 2666MHz CL19 at 1.2V and will down-clock to 2400MHz or 2133MHz if the platform requires it.

Is the 288-pin LRDIMM interface compatible with standard desktop DDR4?

No, the 288-pin ECC Load Reduced DIMM is built for server and workstation platforms and will not fit or function in unbuffered desktop boards.
