Lenovo-Compatible 32 GB DDR4 ECC LRDIMM

This 32 GB DDR4 2133 module is built for Lenovo servers and workstations that require load-reduced ECC memory. It operates at PC4-17000 speed with CL15 latency and 1.2 V power draw. The 288-pin 4Rx4 design targets enterprise platforms needing maximum capacity per slot.

4Rx4 Load-Reduced Architecture

The 4Rx4 organisation and load-reduced buffering lower electrical load on the memory controller, allowing higher densities than standard registered DIMMs. ECC circuitry corrects single-bit errors to protect data integrity in mission-critical workloads. Major OEM DRAM from Samsung, Micron or Hynix is used under rigorous stress testing.

Suited for Lenovo Server Upgrades

Ideal for administrators expanding memory in qualified Lenovo systems using part number 4X70G78059. Not suitable for consumer desktops, laptops or non-ECC platforms that cannot accept 288-pin LRDIMMs. Builders needing unbuffered SODIMMs or higher-frequency modules should look elsewhere.

Questions about this item

Will the 4Rx4 ECC LRDIMM modules need any firmware updates or rank-spare replacements during their service life?

No firmware updates or rank-spare replacements are required; the 4Rx4 ECC LRDIMM modules are validated for continuous server operation without scheduled maintenance.

At what point does the CL15 latency become the bottleneck during sustained memory-intensive workloads?

The CL15 latency is the first limiting factor when the memory controller issues back-to-back random accesses faster than the 15-cycle response window can sustain.

How much heat does the 1.20 V LRDIMM generate when running at 2133 MT/s all day?

At 1.20 V and 2133 MT/s the LRDIMM operates within standard server thermal limits without a heat spreader, relying on chassis airflow for cooling.
