64GB DDR4 3200 ECC Registered DIMM

This OWC module provides 64GB of DDR4 3200 ECC registered memory in a single 288-pin DIMM. It operates at 1.2V with CL22 latency and a 2Rx4 rank configuration. The part is designed for server and workstation platforms that require registered ECC memory.

Suits Gigabyte G152-Z12

This memory fits the listed Gigabyte server and workstation boards that support DDR4 3200 registered ECC DIMMs. It will not work in standard desktop computers that require unbuffered non-ECC modules. Builders needing unbuffered or load-reduced ECC memory should look elsewhere.

Verify registered ECC support and slot availability

Confirm your motherboard accepts 288-pin DDR4 registered ECC RDIMMs and has a free slot for a 64GB module. The board must support 1.2V operation and the 2Rx4 organisation. Check the system manual for maximum capacity per slot and total supported memory before ordering.

Questions about this item

What motherboard and processor combination is required to run this registered ECC DDR4 module?

The module is validated for Gigabyte G152-Z12, H262-Z61, H262-Z62, H262-Z63 and H262-Z66 platforms that support registered ECC DDR4 memory.

Can this 64 GB 3200 MHz RDIMM operate alongside existing 2133 MHz or 2400 MHz ECC registered modules?

Yes, backward compatibility is specified for 2133 MHz, 2400 MHz, 2666 MHz and 2933 MHz speeds; the system will run all modules at the lowest common frequency.

How can I confirm the module is running at 3200 MHz with ECC active after installation?

Enter the system BIOS or use an OS-level tool such as dmidecode to verify the reported speed of 3200 MHz and that ECC is shown as enabled.
