Server memory upgrade

The OWC 64GB DDR4 3200 ECC Registered RDIMM is a single 288-pin module built for Gigabyte G242-Z12, G262-ZO0, G292-Z40, G292-Z42 and G292-Z43 systems. It targets administrators upgrading workstations, servers or NAS units that require registered ECC memory.

Compatibility check

Verify that your platform supports DDR4 ECC Registered DIMMs and cannot accept unbuffered or load-reduced modules. The module runs at 1.2V with CL22 timings and is backward compatible with 2133, 2400, 2666 and 2933MHz bus speeds.

Thermals and power

The module operates at the standard 1.2V DDR4 voltage without a heat spreader. Registered buffering adds minimal electrical load, so power draw stays within typical DDR4 limits and acoustic impact is negligible in normal server airflow.

Questions about this item

Does the 288-pin DDR4 3200 ECC Registered RDIMM arrive as a single 64 GB module, or must I buy additional sticks?

The upgrade consists of one 64 GB 2Rx4 registered DIMM; no extra modules are included.

Should I choose this 64 GB 3200 MHz CL22 kit or a lower-capacity alternative for my Gigabyte G292-Z42?

This single 64 GB stick runs at 3200 MHz with CL22 latency and is validated for the G292-Z42; select it when you need maximum capacity per slot.

What does the 3200 MHz rating mean once the module is installed in a server that only supports 2666 MHz?

The DIMM will down-clock to 2666 MHz automatically while keeping ECC registered operation intact.
