OWC 64GB DDR4 3200 ECC RDIMM

This single 64GB DDR4 3200 PC4-25600 CL22 2Rx4 288-pin 1.2V ECC Registered DIMM is built for servers, workstations and NAS systems. It is not compatible with standard desktop computers.

Compatibility and configuration checks

Verify that your system accepts DDR4 ECC Registered RDIMMs and matches one of the listed Gigabyte models: G492-Z52, H242-Z10, H242-Z11, H252-3C0 or H252-Z10. Do not mix this module with unbuffered or load-reduced memory.

Thermals, noise and power

The module runs at 1.2V without a heat spreader, drawing minimal power and producing no audible noise. Passive cooling relies on chassis airflow, and JEDEC-standard operation keeps temperatures within normal server limits.
