Lenovo-compatible DDR4 2133 LRDIMM

This 32 GB DDR4 2133 module is built for Lenovo servers and workstations that require load-reduced ECC memory. It targets IT teams maintaining qualified platforms where registered DIMMs are mandatory and capacity per slot must stay high.

Thermals, noise and power at 1.2 V

Operating at 1.20 V, the module draws minimal power and produces no audible noise because it has no heat spreader or moving parts. Thermal output scales with the number of populated slots, so dense configurations benefit from the lower voltage.

Single specification that decides fit

The 288-pin LRDIMM form factor with 4Rx4 organisation and CL15 latency only works in motherboards qualified for load-reduced DDR4 2133; systems expecting standard RDIMM or UDIMM will not post with this module installed.

Questions about this item

How do I install the 288-pin LRDIMM in my Lenovo server, and which step is often missed?

Align the notch on the module with the slot key, press down firmly until both side clips lock automatically, then verify in BIOS that the 32GB capacity and 2133 speed are recognised.

What maintenance or replacement will this ECC LRDIMM need over its service life?

The module has no moving parts or heat spreader, so no routine maintenance is required; replacement is only necessary if a memory test reports uncorrectable ECC errors.

What limit appears first when the 4Rx4 LRDIMM runs sustained workloads at 1.2V?

The CAS latency of CL15 at 2133 MT/s sets the throughput ceiling before voltage or thermal constraints become factors.
