Single 128GB DDR5 ECC Registered Module

This OWC module delivers 128GB of DDR5 4800 memory in a single 288-pin RDIMM. It operates at 1.1V with CL40 latency and uses a 4Rx4 organisation. The registered buffer and on-die ECC protect data integrity in multi-module configurations. It is validated for the Gigabyte H223-Z10, H233-Z80, H253-Z10, H273-Z80 and H273-Z81 platforms.

For Workstation and Server Upgrades Only

This memory suits administrators expanding compatible Gigabyte workstations, NAS units or servers that require registered ECC DDR5. It will not function in standard desktop motherboards or consumer laptops. Builders needing unbuffered non-ECC DDR5 or load-reduced DIMMs must select a different module type.

Registered ECC DDR5 Form Factor

The 288-pin registered ECC RDIMM form factor is the sole physical and electrical interface that determines fit. Only systems designed for DDR5 registered ECC modules can accept this part.
