Lenovo-Compatible 64GB LRDIMM

This 64GB DDR4 module uses load-reduced ECC technology to maximize memory capacity in supported Lenovo servers. The 288-pin form factor fits standard DDR4 DIMM slots. It is built for administrators who need to increase virtual-machine density or eliminate swapping on existing hardware without replacing the entire platform.

1.2V CL15 registered design

Operating at 1.20 volts with CL15 latency, the module draws less power per gigabyte than older registered DIMMs while maintaining signal integrity across four ranks. The load-reduced buffer reduces electrical load on the memory controller, allowing higher total capacity per channel. Major-brand chips from Samsung, SK Hynix or Micron ensure consistent quality.

Upgrade for memory-constrained deployments

Adding this LRDIMM extends the usable life of a Lenovo server by removing the memory bottleneck that limits virtualization and database workloads. It is not suited for systems that only accept standard RDIMMs or unbuffered DIMMs, nor for platforms limited to lower maximum capacities per slot.

Questions about this item

What DDR4 speed and PC4 rating does this 64GB LRDIMM run at?

It operates at DDR4-2133, which is the PC4-17000 data rate. The module is built to that JEDEC speed grade and will clock at 2133 MT/s when the platform supports it.

Does this 288-pin LRDIMM need any special socket or keying beyond a standard DDR4 slot?

It uses the standard 288-pin DDR4 form factor and fits any DDR4 LRDIMM-capable server slot. The only requirement is that the motherboard and CPU support load-reduced modules at this density.

How is the module installed and what step do installers often miss?

Power down the server, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until both ejector tabs click shut, then power on and verify the full 64GB appears in BIOS or the OS.
