Lenovo 01DE975 Compatible LRDIMM
This 64GB DDR4 2666 ECC load-reduced module is built for Lenovo servers and workstations that require registered memory with error correction. It suits IT teams expanding capacity in supported platforms without mixing unbuffered or standard registered DIMMs.
Upgrade from lower-density or non-ECC DDR4
Replacing smaller LRDIMMs or non-ECC modules with this 4Rx4 64GB stick adds substantial capacity while maintaining signal integrity on loaded memory buses. The jump is worth it when the platform qualifies PC4-21300 CL19 1.2V parts and the workload demands maximum DIMM density per slot.
Tool-free DIMM installation with standard alignment
The 288-pin form factor seats in the usual DDR4 server slots; ejector clips secure the module once pressed evenly. Common issues arise when the system BIOS does not recognise the 4Rx4 organisation or when mixed-rank populations violate the platform memory population rules.

Perguntas sobre este artigo
Does the 288-pin DDR4 LRDIMM fit a standard server DIMM slot?
Yes, the 288-pin DDR4 LRDIMM form factor matches standard DDR4 server DIMM slots used in compatible Lenovo systems.
What BIOS setting or population rule is often missed when installing this 4Rx4 load-reduced module?
Load-reduced DIMMs require the memory controller to support LRDIMM protocol; verify the server BIOS is updated and the slot population order follows the Lenovo service guide for 4Rx4 modules.
Will the Samsung, Micron or Hynix DRAM chips on this module need replacement during the server's lifespan?
The DRAM chips are soldered to the PCB and are not user-replaceable; if a chip fails the entire 64GB module must be replaced.
