OWC 128GB (4x32GB) DDR5 5600 PC5-44800 CL46 2Rx4 288-pin 1.1V ECC Registered RDIMM server RAM

128GB DDR5 ECC Registered Kit

This 128GB kit contains four 32GB DDR5 5600 modules built to the PC5-44800 standard with CL46 latency. Each 288-pin RDIMM operates at 1.1V and uses a 2Rx4 organisation with on-die ECC and register buffering. The memory is designed for workstations, servers, NAS appliances and network switches that require registered ECC DDR5.

Registered ECC DDR5 Constraints

Registered ECC DDR5 modules will not function in standard desktop platforms that expect unbuffered non-ECC memory. They also cannot be mixed with unbuffered or load-reduced DIMMs in the same system. The 288-pin form factor fits only DDR5 RDIMM slots wired for registered operation. Compatibility must be verified against the platform qualified-vendor list before purchase.

128GB Capacity For Multi-Threaded Workloads

The 128GB total capacity provides headroom for virtualisation hosts, database buffers and large-file editing across multiple simultaneous tasks. Workloads that exceed this limit will require higher-density modules or additional memory channels supported by the platform. The dual-channel kit layout populates four slots, leaving further expansion dependent on the motherboard slot count and memory-controller limits.
