Server ECC RDIMM Kit

This OWC kit provides 128 GB of DDR5 memory in two 64 GB registered DIMMs. It is built for the Lenovo ThinkSystem SR950 V3 and will not work in standard desktop computers.

Build Integration

Each module uses a 288-pin DDR5 interface at 1.1 V with CL40 timing and a 2Rx4 organisation. The registered design requires a platform that supports ECC registered memory and cannot be mixed with unbuffered or load-reduced modules.

Target Buyer

Suitable for administrators expanding a ThinkSystem SR950 V3 or deploying new server builds that demand ECC registered DDR5. Not for desktop users, workstations needing unbuffered DIMMs, or systems limited to lower-density modules.

I korthet

  • 128 GB total capacity from two 64 GB modules
  • DDR5 4800 speed with CL40 latency for server workloads
  • ECC registered design detects and corrects data errors
