64GB DDR5 ECC RDIMM for Gigabyte servers

This 64GB DDR5 4800 ECC Registered RDIMM is built for Gigabyte E163-Z30, E263-Z30, E283-Z90, E283-Z91 and G293-Z20 systems. It targets administrators expanding memory in workstations, servers or NAS appliances that require registered error-correcting modules. The single-module design adds 64GB capacity in one slot.

Installation notes and common issues

The module uses a standard 288-pin DDR5 form factor and installs like any RDIMM; align the key notch and press until the latches click. It will not work in standard desktop boards that accept only unbuffered memory, and it cannot be mixed with unbuffered or load-reduced ECC modules. Systems must support registered ECC at 1.1V for the module to initialise.

Verify platform and memory rules before ordering

Confirm the exact Gigabyte model number matches the supported list above. Check the system documentation for maximum registered DIMM capacity per slot and total channel population limits. Ensure the BIOS is updated to a version that recognises DDR5 4800 registered modules. Do not combine this stick with unbuffered or load-reduced ECC memory in the same platform.

商品問答

How can I verify the module is running at DDR5 4800 CL40 with ECC registered operation after installation?

Check the BIOS or UEFI memory information screen; it should report DDR5 4800 (PC5-38400), CAS latency 40, 1.1 V and show ECC registered mode active.

What ships with the OWC 64GB DDR5 4800 ECC RDIMM and what must be purchased separately?

The box contains the single 64 GB 288-pin DDR5 ECC registered DIMM (part number 4R8D52R464GB); no additional cables, brackets or software are included.

Which OWC DDR5 ECC RDIMM capacity should I choose for a Gigabyte E283-Z90 server?

This 64 GB 2Rx4 module (4R8D52R464GB) is listed as compatible with the E283-Z90; select it when you need a single 64 GB registered DIMM for that platform.
