OWC 128GB (8x16GB) DDR5 5600 PC5-44800 CL46 1Rx4 288-pin 1.1V ECC Registered RDIMM Server RAM

OWC 128GB DDR5 5600 ECC RDIMM Kit

This kit provides 128GB of DDR5 5600 registered ECC memory in eight 16GB modules. It is built for workstations and servers that require 288-pin RDIMM modules with error correction. The memory operates at 1.1V and meets JEDEC PC5-44800 specifications. Standard desktop systems cannot use this registered ECC memory.

Capacity and headroom for virtualization workloads

Eight 16GB modules deliver 128GB total capacity for multi-VM environments and large dataset handling. CL46 latency at 5600 MT/s supports sustained throughput in dual-channel configurations. The 1Rx4 organization fits dense memory slots without exceeding rank limits. Systems needing more than 128GB or unbuffered memory must choose a different kit.

Thermals noise and power at 1.1V

Modules run at the JEDEC standard 1.1V without a heat spreader, relying on chassis airflow for cooling. Low voltage reduces power draw per DIMM in populated server boards. Passive operation adds no fan noise to the system. Dense 8-module populations need adequate case ventilation to maintain stable temperatures.
