OWC 128GB DDR4 3200 ECC Load Reduced LRDIMM memory upgrade

OWC 128GB DDR4 ECC LRDIMM module

This OWC module is a 128GB DDR4 3200 ECC load-reduced DIMM built for server and workstation platforms. It operates at 1.2V with CL22 latency and a 4Rx4 rank structure on a 288-pin form factor. The part is validated for Gigabyte R162-Z11, R162-ZA0, R162-ZA1, R162-ZA2 and R181-Z90 systems. JEDEC and RoHS compliance support a warranty-safe upgrade.

Suited for servers needing high-capacity LRDIMMs

Buyers expanding memory in the listed Gigabyte servers or compatible Micron, Samsung, Hynix and Dataram part numbers will find a direct match. The module also runs at 2133, 2400, 2666 and 2933 MHz for backward-compatible deployments. It is not for standard desktop computers and cannot be mixed with unbuffered or registered ECC DIMMs. Systems without load-reduced memory controllers will not support this module.

128GB capacity per module

Each DIMM delivers 128GB in a single slot, allowing high total memory without occupying every socket. The 4Rx4 organisation and load-reduced buffering reduce electrical load on the memory bus at this density. This capacity figure is the primary specification that determines whether the module meets the target system's maximum supported memory per slot.
