32GB DDR4 2133 ECC LRDIMM Module

This A-Tech server memory module delivers 32GB of DDR4 2133 (PC4-17000) capacity in a single 288-pin LRDIMM. It operates at 1.2V standard voltage with CL15 latency and features 4Rx4 organisation with ECC error correction. The load-reduced design helps reduce electrical load on the memory bus for dense server configurations.

Suits admins upgrading compatible IBM-Lenovo systems

This module replaces specific IBM-Lenovo part numbers including 00KH391, 03T7863, 46W0799, 46W0800, 46W0802, 47J0254, 4X70F28591 and 4X70G78059. It is not for desktop PCs or consumer motherboards that cannot use registered ECC LRDIMM modules. Buyers needing non-ECC or standard UDIMM memory should look elsewhere.

Verify your platform supports DDR4 LRDIMM

Before ordering, confirm your server or workstation accepts DDR4 2133 load-reduced ECC DIMMs with 4Rx4 ranking at 1.2V. Check the system documentation for maximum supported capacity per slot and total memory limit. Ensure the BIOS version recognises this module density and organisation.

Questions about this item

What motherboard slot does this 288-pin DDR4 LRDIMM require?

It fits a standard DDR4 DIMM slot with 288 pins; the motherboard must support load-reduced ECC memory at 1.2 V.

Can I mix this 4Rx4 CL15 module with existing 2Rx4 DDR4 2133 ECC RDIMMs?

Mixing LRDIMM and RDIMM types is not supported; all slots must use the same registered or load-reduced technology.

How do I confirm the module runs at PC4-17000 CL15 after installation?

Check the BIOS memory information or use a tool such as CPU-Z; it should report 2133 MT/s, CL15 timings and ECC LRDIMM status.
