Lenovo-compatible 32GB DDR4 ECC LRDIMM

This 32GB DDR4 2133 module is built for Lenovo servers and workstations that require ECC load-reduced memory. It operates at 1.2V with CL15 timing and a 4Rx4 organisation. The 288-pin form factor fits supported enterprise platforms.

Sustained load behaviour

ECC circuitry corrects single-bit errors during continuous operation, helping data integrity under heavy workloads. Load-reduced buffering reduces electrical load on the memory controller when multiple modules are populated. The 1.2V rating keeps power draw steady during extended runs.

Upgrade context

This module replaces non-ECC or lower-capacity DDR4 DIMMs in compatible Lenovo systems. The jump is worthwhile when workloads demand error correction and higher density per slot. It is not suited for platforms that only accept standard registered or unbuffered DDR4 memory.

Questions about this item

How much power does the 1.2 V DDR4 2133 CL15 LRDIMM draw under continuous server load?

The module is rated at 1.20 V; DDR4 LRDIMMs at this voltage typically consume a few watts per stick during sustained operation, keeping heat output low in a populated chassis.

What must the Lenovo system already provide for this 288-pin ECC LRDIMM to function?

A DDR4 LRDIMM-capable memory controller, ECC support, and an available 288-pin DIMM slot are required; the board must also accept 4Rx4 organisation and PC4-17000 speed.

Will the CL15 2133 MHz timing work alongside existing DDR4 2133 RDIMMs in the same Lenovo server?

Mixing LRDIMM and RDIMM types on one platform is not supported; all populated slots must use the same registered or load-reduced technology for the system to boot.
