128GB DDR5 ECC RDIMM for Gigabyte R163 servers

This 128GB DDR5 5600 CL46 module is built for Gigabyte R163-S30, R163-S32, R163-S35, R163-SG0 and R163-SG2 systems. It targets administrators who need registered ECC memory for stable server, workstation or NAS operation. The single DIMM delivers 128GB capacity in a 288-pin form factor. It is not for standard desktop computers or unbuffered memory configurations.

Installation notes and common issues

The module inserts into a standard 288-pin DDR5 slot and runs at 1.1V. Because it is a 4Rx4 registered ECC DIMM, it must not be mixed with unbuffered or load-reduced memory. Systems that require matched populations may need identical modules in specific channels. Always verify the motherboard manual for supported rank limits and population rules before installing.

Deciding specification: registered ECC

The registered ECC design with 4Rx4 organisation is the single factor that determines compatibility. Only platforms that explicitly support registered ECC RDIMMs at this rank configuration will accept the module. Buyers who need unbuffered memory, load-reduced DIMMs or a different rank structure must choose another part.

Questions about this item

How can I confirm the module is running at 5600 MT/s with CL46 after installing it in a Gigabyte R163-S30?

Enter the system BIOS or UEFI and verify the memory speed reads 5600 MT/s (PC5-44800) and the CAS latency shows 46; the registered ECC design will also report its ECC status as active.

What comes in the box with the OWC 128GB DDR5 5600 ECC RDIMM, and do I need any extra parts for a Gigabyte R163-SG2?

The package contains a single 128 GB 288-pin DDR5 5600 CL46 4Rx4 1.1 V ECC registered RDIMM; no additional components are required for the listed Gigabyte R163 models.

Which capacity and rank option should I choose for a Gigabyte R163-S35 that needs 128 GB in one slot?

This module is a single 128 GB 4Rx4 registered ECC DIMM, so one unit fills one slot with the full 128 GB capacity supported by the R163-S35.
