DDR5 4800 ECC Registered Kit

This OWC kit provides 128 GB of DDR5 4800 memory in two 64 GB registered DIMMs. Each module runs at 1.1 V with CL40 latency and 2Rx4 organisation. The 288-pin RDIMMs include on-die ECC for data integrity in server and workstation environments.

For Lenovo ThinkSystem Servers

The upgrade is validated for ThinkSystem SD650 V3, SD650-I V3, SD665 V3, SD665-N V3 and SR630 V3 platforms. It will not work in standard desktop PCs or consumer motherboards. Builders who need unbuffered or load-reduced DIMMs must choose a different memory type.

JEDEC Compliant, No Heat Spreader

The modules meet JEDEC and RoHS standards for warranty-safe installation. A limited lifetime warranty and free technical support are included. The absence of a heat spreader keeps the profile low for dense server chassis, but buyers needing active cooling should verify airflow in their specific system.
