OWC 128GB DDR5 4800 CL40 ECC Registered RDIMM 4Rx4 1.1V 288-pin Gigabyte R163-Z30 Z32 Z35 R183-Z90 Z91

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.
