OWC 128GB DDR5 5600 CL46 4Rx4 288-pin 1.1V ECC Reg RDIMM memory upgrade

128GB DDR5 ECC RDIMM for Gigabyte servers

This 128GB DDR5 5600 CL46 registered DIMM is built for Gigabyte G593 and H223 server platforms. It delivers ECC error correction and registered signalling required by workstation and server motherboards. The single module format simplifies capacity scaling in qualified systems. It will not function in standard desktop computers or alongside unbuffered memory.

Sustained load behaviour

Registered buffering and on-die ECC maintain data integrity during continuous multi-threaded workloads typical of virtualisation and database tasks. The 1.1V operating voltage keeps power draw predictable across fully populated channels. JEDEC-standard timings ensure stable operation without manual tuning. Heat spreaders are absent, so airflow across the DIMMs must be managed by the chassis design.

4Rx4 rank architecture

The quad-rank 4Rx4 organisation packs 128GB into one 288-pin slot, maximising density per channel on compatible Gigabyte boards. This rank structure is the decisive factor for memory-controller compatibility and total system capacity limits. Verify the platform qualified-vendor list before purchase, as mixing with load-reduced or unbuffered DIMMs is not supported.
