64GB DDR3L ECC Registered Kit

This kit provides 64GB of DDR3L server memory across eight 8GB registered DIMMs. It is built for workstations, servers, NAS systems and routers that require ECC registered modules. The 240-pin form factor fits compatible DDR3L slots in enterprise hardware. OWC tests each module to meet JEDEC and RoHS standards.

Suited for registered ECC platforms only

This memory fits systems that explicitly support DDR3L 1866 CL13 registered ECC DIMMs at 1.35V. It will not work in standard desktop computers that require unbuffered non-ECC modules. It also cannot be mixed with unbuffered memory in the same platform. Buyers needing unbuffered desktop memory or non-ECC consumer DIMMs should look elsewhere.

Registered ECC with 1Rx4 organisation

The decisive specification is the registered ECC design with a single-rank 1Rx4 layout. Only motherboards and controllers qualified for registered ECC DDR3L at this speed and voltage will accept the kit. Verify your platform’s memory qualification list before ordering.

Questions about this item

Will the 240-pin DDR3L RDIMM modules fit in a standard desktop motherboard?

No, the 240-pin DDR3L RDIMM modules are keyed for registered server platforms and will not seat in desktop DIMM slots.

Do I need to populate all eight slots or can I install them in pairs for dual-channel operation?

Install the eight 8 GB modules in matched pairs per channel; the kit is validated as a dual-channel set, so populate slots in the order your server manual specifies.

How long will the 1.35 V DDR3L ECC registered modules last before they need replacement?

The modules carry a limited lifetime warranty and are built to JEDEC standards, so replacement is only required if a module fails or capacity needs increase.
