32GB DDR3L ECC LRDIMM Server Module

This 32GB DDR3L 1600 ECC LRDIMM module is built for servers and workstations that require load-reduced registered memory. It operates at 1.35V with a CL11 latency and uses a 4Rx4 rank configuration on a 240-pin DIMM form factor. The part replaces IBM-Lenovo 46W0675, 46W0676, 46W0678 and 47J0227.

Verify DDR3L Slot and LRDIMM Support

Before ordering, confirm that your system accepts DDR3L 1.35V memory and specifically supports load-reduced DIMMs. Standard registered or unbuffered DDR3 modules are not interchangeable with this LRDIMM design. Check the motherboard or server documentation for the qualified vendor list and maximum supported capacity per slot.

Upgrade From Lower-Capacity DDR3L RDIMMs

This module replaces lower-density DDR3L registered DIMMs when the platform supports LRDIMM technology and 4Rx4 organisation. The jump is worthwhile when the memory controller can address the higher rank count and the workload benefits from the increased 32GB density per slot. It does not fit systems limited to standard RDIMM or UDIMM populations.

Questions about this item

Does the single 32 GB DDR3L 1600 module ship alone or with extra parts?

The listing describes one 32 GB DDR3L 1600 ECC LRDIMM; no additional components are mentioned.

How do I choose between the listed IBM-Lenovo part numbers 46W0675, 46W0676, 46W0678 and 47J0227?

All four part numbers reference the same 32 GB DDR3L 1600 ECC LRDIMM specification; select the one that matches your system's documented part number.

What does the CL11 1.35 V rating mean for real-world server performance?

CL11 at 1.35 V indicates standard DDR3L 1600 latency and low-voltage operation for compatible ECC LRDIMM server platforms.
