32GB DDR3L ECC Registered Kit

This OWC kit supplies 32GB of DDR3L memory in four 8GB registered DIMMs. It is built for workstations, servers, NAS devices and routers that require ECC error correction and registered buffering. The modules run at 1066MHz with CL7 latency and operate at the low 1.35V DDR3L voltage.

Who this suits and who it does not

The kit suits administrators upgrading or repairing DDR3L registered platforms that accept 240-pin ECC RDIMMs. It will not work in standard desktop computers, in systems that require unbuffered non-ECC DIMMs, or in boards that only support higher-voltage DDR3. Buyers needing different capacities, speeds or form factors should look elsewhere.

Deciding specification — 1.35V DDR3L registered ECC

The single decisive detail is the combination of 1.35V DDR3L voltage, registered buffering and ECC on a 240-pin DIMM. Only systems explicitly qualified for this exact electrical and signalling profile will recognise and run the modules reliably.

Questions about this item

Will the 1.35 V DDR3L voltage limit how long I can run the kit at full load?

The modules operate at the standard 1.35 V DDR3L level, so sustained full-load operation stays within JEDEC limits without additional voltage stress.

How much heat or noise should I expect from the four 8 GB sticks when the server runs 24/7?

No heat spreader is fitted, so the DIMMs rely on chassis airflow; they add minimal thermal load and produce no audible noise themselves.

What must my motherboard already provide for this 240-pin registered ECC kit to function?

The board needs DDR3L 240-pin slots that support registered ECC memory and a memory controller able to address 2Rx4 modules.
