OWC 16GB DDR4 ECC Registered RDIMM

This 16GB DDR4 module runs at 2133MHz with CL15 latency and 1.2V operation. It uses a 288-pin registered DIMM design with ECC for error correction. The memory is built specifically for the Lenovo Flex System x240 M5 server platform.

Capacity and headroom for virtualised workloads

A single 16GB stick adds substantial memory headroom for virtual machines, databases and multi-user applications. The registered buffer reduces electrical load on the memory controller, allowing larger configurations. Workloads that exceed this capacity will require additional modules to scale further.

Compatibility limited to supported Lenovo servers

This module replaces Lenovo part numbers 46W0795, 46W0796, 4X70F28590, 4X70G78062 and 95Y4821. It will not work in standard desktop computers or systems requiring unbuffered memory. Mixing with non‑registered DIMMs is not supported.

商品問答

Will the 288-pin DDR4 2133MHz CL15 ECC Registered RDIMM run with my existing Lenovo Flex System x240 M5 memory?

This module is validated for the Lenovo Flex System x240 M5 (E5-2600 v3). It must not be mixed with unbuffered memory; all installed DIMMs must be ECC Registered to function correctly.

How can I verify the 16GB PC4-17000 CL15 1.2V module is detected and running at 2133MHz after installation?

Enter the server BIOS or UEFI and confirm the memory shows 16GB, DDR4-2133, CL15, 1.2V, and ECC Registered status. A successful POST with no memory errors indicates correct operation.

Does the 2R1D42R416GB package include any extra items besides the 288-pin RDIMM itself?

The box contains the single 16GB DDR4 2133MHz CL15 ECC Registered RDIMM. No cables, brackets, or additional accessories are included.
