32 GB DDR3-1866 ECC Registered Kit

This OWC kit supplies 32 GB of DDR3 1866 registered ECC memory across four 8 GB modules. It uses 240-pin RDIMMs rated at PC3-14900 with CL13 latency and 1.5 V operation. The modules are unbuffered-rank 1Rx4 and carry no heat spreader. They are built for workstations, servers, NAS systems and routers that require registered ECC DDR3.

Suits registered-ECC DDR3 platforms.

Buyers maintaining or expanding servers, workstations or NAS units that accept 240-pin registered ECC DDR3 will find a direct JEDEC-compliant upgrade here. Systems that need unbuffered non-ECC memory, a different DDR generation, SODIMM form factor or higher speeds cannot use this kit. Mixing these registered modules with unbuffered DIMMS is also unsupported.

Registered ECC with 1Rx4 organisation

The single specification that decides fit is the registered ECC RDIMM design with 1Rx4 rank structure. Only platforms explicitly qualified for 240-pin DDR3 1866 registered ECC memory at 1.5 V can accept this kit; all other memory controllers will reject it.

Questions about this item

Should I buy the 32GB kit as four 8GB modules or look for a different capacity?

This kit provides 32GB total across four 8GB modules, giving you four populated slots for maximum bandwidth on compatible platforms.

What does the 1866MHz speed mean for actual server workloads?

The modules run at DDR3 1866 (PC3-14900) with CL13 latency, delivering the rated throughput when the platform memory controller supports that frequency.

Will the 240-pin registered ECC interface work in my workstation?

These are 240-pin DDR3 ECC registered DIMMs at 1.5V; they require a workstation or server board that supports registered memory and cannot be mixed with unbuffered modules.
