32GB DDR3L ECC RDIMM kit

This OWC kit provides 32GB of DDR3L 1866 memory across four 8GB registered DIMMs. It targets administrators upgrading compatible workstations, servers or NAS systems that require ECC registered modules. The CL13 latency and 1.35V operation match the JEDEC PC3L-14900 standard for these platforms.

Suits ECC registered platforms only

The modules are built for systems that specifically accept 240-pin DDR3L ECC registered RDIMMs in a 1Rx4 configuration. They will not work in standard desktop computers that use unbuffered memory, nor in platforms that require load-reduced or unregistered ECC DIMMs. Mixing with unbuffered memory is not supported.

Registered ECC decides compatibility

The single specification that determines fit is the registered ECC design combined with the DDR3L 1866 CL13 1.35V 240-pin form factor. Only systems qualified for this exact module type can use the kit; all others must select different memory.

Questions about this item

How much power does the 1.35V DDR3L kit draw when the server runs all day?

Each module operates at 1.35V, lower than standard DDR3, reducing heat and power draw during continuous workloads.

What must the system already have to accept these 240-pin registered DIMMs?

A workstation or server motherboard with DDR3L RDIMM slots that supports ECC registered memory; standard desktop boards will not work.

Can I add this CL13 1866MHz kit beside older DDR3L modules already installed?

Only if the existing modules are also ECC registered DDR3L at 1.35V; mixing with unbuffered or different-voltage DIMMs is not supported.
