OWC 64 GB DDR5-5600 ECC RDIMM

This OWC module delivers 64 GB of DDR5-5600 registered ECC memory in a single 288-pin RDIMM. It operates at 1.1 V with CL46 latency and a 2Rx4 organisation. The part is validated for Gigabyte R283-S91 through R283-S95 platforms.

Suited to servers and workstations needing

Buyers upgrading compatible Gigabyte R283 systems can add this module to expand capacity with error-correcting registered memory. It will not work in standard desktop boards that require unbuffered non-ECC DIMMs, nor in systems that only accept load-reduced ECC modules.

Fits DDR5 RDIMM slots in validated Gigabyte servers

The module plugs directly into 288-pin DDR5 RDIMM sockets on the listed R283 platforms. Its registered buffer reduces electrical load on the memory controller, allowing larger total capacities per channel. JEDEC and RoHS compliance ensures straightforward integration without firmware surprises.

Questions about this item

What motherboard must I have to use this 64GB DDR5 5600 ECC registered RDIMM?

This module is validated for Gigabyte R283-S91, R283-S92, R283-S93, R283-S94 and R283-S95 systems.

Can I keep my existing unbuffered ECC DIMMs and add this 2Rx4 registered module?

No. Registered memory cannot be mixed with unbuffered or load-reduced ECC modules.

How do I confirm the module is running at 5600 MT/s with CL46 after installation?

Check the BIOS memory information or a tool like CPU-Z; it should report DDR5-5600, CAS 46, 1.1 V and ECC registered operation.
