32GB DDR5 Server Memory

Key takeaways

  • 855 listings match this collection right now.
  • 32GB DDR5 modules exist as both single-rank and dual-rank builds, the single-rank version using higher-density 16Gb dies and the dual-rank version using 8Gb dies instead.
  • An eight channel Xeon Scalable socket reaches 256GB with a 32GB module in every channel, and a twelve channel EPYC socket reaches 384GB the same way.
  • Populating two 32GB modules per channel instead of one can lower the speed grade the platform runs at, a tradeoff that comes with doubling capacity per channel.

32GB is the mainstream DDR5 module capacity for two-socket servers, where eight or sixteen slots per socket are populated evenly. Registered ECC modules (RDIMM) fit Xeon Scalable and EPYC platforms; unbuffered ECC modules (UDIMM) fit single-socket Xeon E and workstation boards. The two are not interchangeable, so check the module type the system already carries.

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.
