Server Memory Upgrade

This OWC module is a 128GB DDR5 4800 ECC registered RDIMM built for Gigabyte R163-Z30, R163-Z32, R163-Z35, R183-Z90 and R183-Z91 systems. It runs at 1.1V with CL40 latency and a 4Rx4 rank configuration. The 288-pin form factor fits the validated server and workstation platforms listed by the manufacturer. No heat spreader is included.

Workstation And Server Builders

The part suits administrators expanding memory in the named Gigabyte servers or workstations that require registered ECC DDR5. It will not work in standard desktop computers, consumer motherboards or any platform that only accepts unbuffered or load-reduced DIMMs. Buyers needing non-ECC memory or a different voltage should look elsewhere.

128GB Single-Module Capacity

A single DIMM delivers 128GB of registered ECC memory, allowing maximum density per slot in the compatible Gigabyte systems. This capacity is the deciding factor when the board's slot count limits total memory and the workload demands the highest addressable space per channel. Verify the platform's qualified vendor list before purchase.

Questions about this item

Does this 288-pin DDR5 module fit the Gigabyte R163-Z30 server board?

Yes, the 128GB 288-pin DDR5 4800 CL40 ECC Registered RDIMM is validated for Gigabyte R163-Z30, R163-Z32, R163-Z35, R183-Z90 and R183-Z91 systems.

What is the correct way to seat this registered DIMM, and what mistake do installers make?

Align the single key notch with the slot, press straight down until both ejector clips click; the common error is stopping before the clips engage, leaving the module partially seated.

When will this 128GB 4Rx4 DDR5 module need replacement?

DDR5 ECC Registered RDIMMs have no scheduled replacement interval; replace only if memory diagnostics report uncorrectable errors or the server fails to POST with this module installed.
