DDR5-4800 Server Memory
Key takeaways
- 2,084 listings match this collection right now.
- Single-socket Xeon E platforms moved to DDR5 alongside two-socket Xeon Scalable and EPYC, and their unbuffered modules run at this same 4800 launch speed.
- DDR5-4800 modules run at the DDR5 generation's standard 1.1V operating voltage, lower than the 1.2V baseline DDR4 servers use, a difference that holds across every DDR5 speed grade.
- Mixing a 4800-rated module with a 5600-rated module in the same channel is supported, but the whole channel then runs at 4800, the speed of the slower module present.
DDR5-4800 (PC5-38400) is the speed grade the DDR5 server generation launched at, and the one fourth-generation Xeon Scalable and EPYC 9004 platforms run by default. Faster modules downclock to it on these systems, so 4800 remains the safe grade to buy for them.

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.
