OWC 32GB DDR4 ECC RDIMM for Lenovo x3550 M5 x3650 M5

This 32GB DDR4 2400MHz ECC registered DIMM is built for Lenovo System x3550 M5 (8869) and x3650 M5 (8871) servers. It operates at 1.2V with CL17 latency and a 2Rx4 rank configuration. The module replaces Lenovo part numbers 46W0832, 46W0833, 46W0835, 4X70G88320 and 4X70M09263. It is not compatible with standard desktop computers or unbuffered memory.

32GB capacity extends server memory headroom

A single 32GB module adds substantial capacity for virtualization, database caching and multi-user workloads on the supported platforms. The registered design and ECC error correction maintain data integrity under sustained load. Systems requiring larger memory footprints will need additional modules to reach maximum supported capacity.

ECC registered DDR4 288-pin form factor decides fit

This module uses the 288-pin DDR4 ECC registered form factor required by the x3550 M5 and x3650 M5. It will not work in systems that accept only unbuffered UDIMMs or a different DDR generation. Verify your server model and memory slot population rules before ordering.

Questions sur cet article

Will this 32GB DDR4 2400 CL17 ECC RDIMM work alongside my existing memory in the x3550 M5?

This module is compatible with the Lenovo System x3550 M5 (8869) and x3650 M5 (8871). It is ECC registered memory and cannot be mixed with unbuffered memory. Matching speed, voltage, and rank across all installed modules is required for stable operation.

How can I verify the module is running at 2400MHz CL17 after installation?

Enter the system BIOS or UEFI on the x3550 M5 or x3650 M5 and check the memory configuration screen; it should report DDR4 2400 (PC4-19200) with CAS latency 17 at 1.2V. Operating system tools such as dmidecode or CPU-Z will also display the rated speed and timings.

What comes in the box and do I need anything else to install it?

The box contains the 32GB 288-pin DDR4 ECC registered RDIMM (part number 2R4D42R432GB). No additional hardware is required for installation in a compatible Lenovo x3550 M5 or x3650 M5 server; the module slots directly into the DIMM sockets.
