Key takeaways
- 2,318 listings match this collection right now.
- Registered ECC modules are the default DDR5 type for two-socket Xeon Scalable and EPYC platforms, while unbuffered ECC modules serve single-socket boards, and the two types cannot populate one system.
- DDR5 splits each module into two independent subchannels and moves voltage regulation onto the module through an on-board PMIC, a change from DDR4 that raised the ECC design to on-die.
- DDR5 speed grades run from 4800 up through 5600, 6400 and beyond as the generation matures, and each server platform generation is validated for only part of that full range.
DDR5 is the current server memory generation, introduced with Intel Sapphire Rapids and AMD EPYC Genoa platforms. Modules run from DDR5-4800 upward, carry on-module power management, and are keyed so they cannot be fitted to a DDR4 slot.

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.
