DDR3 LRDIMM Server Memory

Key takeaways

  • 577 listings match this collection right now.
  • DDR3 LRDIMM uses the same data-buffering approach as its DDR4 successor, presenting a lighter electrical load so quad-rank modules can populate every slot on a channel at rated speed.
  • Two socket Xeon E5-2600 platforms from v1 onward are the primary users of DDR3 LRDIMM, their memory controllers built to address the higher rank count these modules carry.
  • A bank already running DDR3 RDIMM will not accept an LRDIMM addition, so the installed type has to be confirmed from an existing module before ordering more.

DDR3 LRDIMMs arrived with the Xeon E5 v2 generation to allow 32GB and 64GB modules at full slot population. Like their DDR4 successors they cannot share a system with standard RDIMMs.

How to choose server memory

DDR3, DDR4 and DDR5 modules are keyed differently and do not interchange, so the generation your platform accepts comes first. Registered (RDIMM), load-reduced (LRDIMM) and unbuffered (UDIMM) modules cannot be mixed in one system: add the type already installed, or replace the full bank. Match rank and speed to the existing modules, and read an installed part number from iDRAC or iLO when in doubt.
