OWC 64GB DDR5 ECC RDIMM

This 64GB DDR5 ECC Registered DIMM is built for Gigabyte H223-Z10, H233-Z80, H253-Z10, H273-Z80 and H273-Z81 servers and workstations. It delivers error-correcting memory for workloads that require data integrity. Buyers upgrading standard desktop PCs cannot use this module.

Capacity and headroom for DDR5 4800 systems

The single 64GB module runs at DDR5 4800 with CL40 latency and 1.1V operation, providing substantial headroom for virtualisation, large datasets and multi-user services. Workloads that exceed 64GB per slot will need additional populated channels.

Upgrade path for compatible Gigabyte platforms

It replaces lower-capacity DDR5 ECC RDIMMs in the listed Gigabyte models, letting administrators scale memory without mixing registered and unbuffered types. The jump is worth it when current modules limit container density or database caching.

Questions about this item

Will the 64GB DDR5 4800 CL40 2Rx4 288-pin 1.1V ECC RDIMM run alongside existing registered ECC modules in my Gigabyte H223-Z10?

Yes, it will operate with other DDR5 ECC registered DIMMs at the same 4800 speed and 1.1V voltage; do not mix with unbuffered or load-reduced memory.

How can I confirm the 64GB DDR5 4800 CL40 2Rx4 288-pin 1.1V ECC RDIMM is working correctly after installation?

Check the system BIOS or UEFI to verify the module is detected at 4800 MT/s with ECC active, then run a memory diagnostic to confirm error-correction operation.

What ships with the OWC 64GB DDR5 4800 CL40 2Rx4 288-pin 1.1V ECC RDIMM and what must I source separately?

The box contains the single 64GB registered DIMM; no heat spreader, cables or additional modules are included.
