64GB DDR3L ECC Registered Kit

This OWC kit supplies 64GB of DDR3L 1600 CL11 ECC registered memory in eight 8GB modules. It is built for workstations, servers, NAS systems and routers that require 240-pin DDR3L RDIMMs with 1.35V operation and 1Rx4 organisation.

Verify 240-pin DDR3L RDIMM support

Before ordering, confirm that your platform accepts 240-pin DDR3L ECC registered DIMMs at 1.35V and that it can populate eight slots in a dual-channel configuration. Registered modules will not work in systems that only support unbuffered memory, and they cannot be mixed with unbuffered DIMMs.

Replaces lower-capacity DDR3L RDIMM sets

The kit replaces smaller DDR3L registered kits when the platform has eight available slots and the workload benefits from 64GB of ECC-protected memory. The upgrade is worthwhile when the existing modules are slower, fewer in number, or lack error correction.
