OWC 64GB DDR4 ECC Registered RDIMM

This OWC module provides 64GB of DDR4 server memory at 3200MHz with CL22 latency. It uses a 2Rx4 registered ECC design and operates at 1.2V. The 288-pin RDIMM is built for workstations and servers that require error-correcting registered memory.

Verify registered ECC support before ordering

This memory will not work in standard desktop computers that use unbuffered non-ECC modules. Your system must support DDR4 registered ECC RDIMMs and accept 2Rx4 rank configuration. Mixing this module with unbuffered memory is not supported.

Thermals and power in normal use

The module runs at the standard 1.2V DDR4 voltage without a heat spreader. Registered ECC operation adds minimal overhead compared to unbuffered equivalents. Expect typical power draw for a 64GB DDR4 RDIMM under normal server workloads.
