Server ECC RDIMM upgrade

This OWC module provides 64GB of DDR4 3200 registered ECC memory for specific Gigabyte server platforms. It operates at 1.2V with CL22 latency and a 2Rx4 rank configuration. The 288-pin RDIMM is designed for workstation and server environments requiring error correction.

Not for desktop or unbuffered systems

This memory will not work in standard desktop computers or consumer motherboards. It cannot be mixed with unbuffered or load-reduced ECC modules. Buyers needing non-ECC memory or laptop SODIMMs should look elsewhere.

Registered ECC with 2Rx4 organization

The registered buffer and ECC functionality are the decisive specifications for compatibility with the listed Gigabyte R272-Z34, R281-Z91, R281-Z92, R281-Z94 and R282-2O0 systems.

Questions about this item

Will the 2Rx4 ECC registered DIMM need replacement if a rank fails?

A single 64 GB 2Rx4 module contains two ranks; if one rank fails the whole DIMM must be replaced because ECC registered memory does not allow per-rank repair.

What speed ceiling appears first when this module runs continuously in a Gigabyte R281-Z92?

The module is rated for 3200 MHz CL22 at 1.2 V; sustained loads will hit that JEDEC speed limit before any higher frequency can be reached.

How much heat does the 1.2 V registered DIMM produce during all-day server use?

Operating at 1.2 V with no heat spreader, the 64 GB DDR4 RDIMM draws standard registered-DIMM power and relies on chassis airflow for cooling.
